[0176] Allium Macrostemonis Solution 4: 4 g of Allium Macrostemonis powder (YF210101) was dissolved in 100 ml of water, 1 ml of n-hexane was added to the volatile oil extractor and heated to reflux for 30 minutes, the n-hexane liquid was collected and used as the Allium Macrostemonis solution 4.

[0178] Ten microliters of Allium Macrostemonis Solution 1, Test Solution 1 and Allium Macrostemonis Solution 2 were spotted on the same silica gel G thin layer plate, developed with n-hexane-ethyl acetate (10:1), taken out, dried, sprayed with 10% sulfuric acid ethanol solution, heated at 105°C until the spots were clearly colored, and observed under daylight and ultraviolet light (365 nm).
[0179] The results are shown in Figure 3 , Figure 3 The left and right graphs are the results of observing the three samples under daylight (left graph) and ultraviolet light (right graph). Figure 3 In the left and right graphs, from left to right, the samples are Allium Macrostemonis Solution 1, Test Solution 1 and Allium Macrostemonis Solution 2.
[0180] Take 10 μl of each of the five solutions, Baijiangliangqie medicinal material solution ②, test solution ②, Baijiangliangqie medicinal material solution ③, Baijiangliangqie medicinal material solution ④, Baijiangliangqie medicinal material solution ⑤, and spot them on the same silica gel G thin layer plate. Use n-hexane-ethyl acetate (10:1) as the developing agent, develop, take out, dry, spray with 10% sulfuric acid ethanol solution, heat at 105°C until the spots develop clearly, and observe under daylight and ultraviolet light 365 nm.
[0181] The results are shown in Figure 4 , Figure 4 The results of observing the five samples under daylight (left graph) and ultraviolet light (right graph) are shown in the following figures. Figure 4 In the left and right graphs, the samples from left to right are Baijiangliangqie medicinal material solution ②, test solution ②, Baijiangliangqie medicinal material solution ③, Baijiangliangqie medicinal material solution ④, and Baijiangliangqie medicinal material solution ⑤.
[0182] From Figure 3 and Figure 4 , it can be seen that in the treatment method provided by Comparative Example 2, the treatment process of Baijiangliangqie medicinal material solution ② reproduces the method of the Pharmacopoeia, and using the identification method of the Pharmacopoeia can obtain fluorescent spots, indicating that there is no error in the experiment. The Baijiangliangqie components in test solution ② and Baijiangliangqie medicinal material solution ③ are water decoction components, i.e. water-soluble components, and using the identification method of the Pharmacopoeia does not find the expected fluorescent spots; Baijiangliangqie medicinal material solution ④ is a distillated volatile lipid-soluble component, and using the identification method of the Pharmacopoeia also does not find the expected fluorescent spots; Baijiangliangqie medicinal material solution ⑤ is the residue after water decoction of Baijiangliangqie medicinal material, and using the treatment and identification method of the Pharmacopoeia can obtain the expected fluorescent spots.
[0183] From the experiment of the treatment method provided by Comparative Example 2, it can be seen that the identification method of Baijiangliangqie medicinal material in the Pharmacopoeia identifies lipid-soluble components, while the water decoction process of Chinese patent medicines containing Baijiangliangqie medicinal material and single decoction preparations cannot identify the lipid-soluble components, which remain in the residue of Baijiangliangqie medicinal material and are not extracted by the water decoction process. Therefore, the Pharmacopoeia method cannot identify the water-soluble components in Baijiangliangqie.

[0187] Negative Solution 2 for Zhishi Xiebai Guizhi Decoction lacking Xiebai: Take 100ml of negative sample (21030805) of Zhishi Xiebai Guizhi Decoction lacking Xiebai, extract it twice with ethyl acetate, 30ml each time, discard the ethyl acetate solution, extract the aqueous solution twice with n-butanol, 30ml each time, combine the n-butanol solutions, evaporate to dryness, add 1ml of methanol to dissolve the residue, and use it as negative solution 2 for Zhishi Xiebai Guizhi Decoction lacking Xiebai (referred to as "Negative 2").
[0188] Test solution 1 of Zhishi Xiebai Guizhi Decoction: Take 100ml of Zhishi Xiebai Guizhi Decoction (21031601), extract it twice with ether (30ml each time), discard the ether solution, extract the aqueous solution twice with n-butanol (30ml each time), combine the n-butanol solutions, evaporate to dryness, dissolve the residue in 1ml of methanol, and use this as test solution 1 of Zhishi Xiebai Guizhi Decoction (referred to as "Decoction 1").
[0189] Test solution 2 of Zhishi Xiebai Guizhi Decoction: Take 100ml of Zhishi Xiebai Guizhi Decoction (21031601), extract it twice with ethyl acetate, 30ml each time, discard the ethyl acetate solution, extract the aqueous solution twice with n-butanol, 30ml each time, combine the n-butanol solutions, evaporate to dryness, dissolve the residue in 1ml of methanol, and use it as test solution 2 of Zhishi Xiebai Guizhi Decoction (hereinafter referred to as "Decoction 2").
[0190] Test solution 3 of Zhishi Xiebai Guizhi Decoction: Take 100ml of Zhishi Xiebai Guizhi Decoction (21031601), extract it twice with n-butanol, 30ml each time, combine the n-butanol solutions, evaporate to dryness, dissolve the residue in 1ml of methanol, and use it as test solution 3 of Zhishi Xiebai Guizhi Decoction (hereinafter referred to as "Decoction 3").
[0191] Take 10 μl of each of the six solutions, namely "Allium macrostemon", "Anion 1", "Anion 2", "Soup 1", "Soup 2" and "Soup 3", and spot them separately on the same silica gel G thin-layer plate. Use ethyl acetate-glacial acetic acid-formic acid-water (15:1:1:2) as the developing solvent, develop, remove, air dry, spray with 10% sulfuric acid ethanol solution, heat at 105℃ until the spots are clearly visible, and examine under sunlight and ultraviolet light at 365 nm.
[0192] See results Figure 5 , Figure 5 The chromatogram obtained by the processing method provided for Comparative Example 3. Figure 5 In the middle, from left to right, the samples are "Allium macrostemon" solution, "Antagon 1" solution, "Antagon 2" solution, "Soup 1" solution, "Soup 2" solution, and "Soup 3" solution.
[0193] Depend on Figure 5 It is known that *Allium macrostemon* mainly contains saponins, and n-butanol is most suitable for extracting saponins from the decoction. Therefore, the preparation method for the test sample was to use n-butanol-water liquid-liquid extraction. For solutions "Soup 1" and "Soup 2," ether and ethyl acetate were used respectively for impurity removal to remove some lipid-soluble impurities from the aqueous solution. Solution "Soup 3" was not pre-treated for impurity removal. Figure 5 It can be seen that in the n-butanol extract of the decoction of Allium macrostemon ("Allium macrostemon" solution), there are several well-separated fluorescent spots, one of which is brighter, indicating that the method (sample processing method, silica gel G thin-layer plate, developing solvent, colorimetric reagent, 365 UV light) can be used to identify the water-soluble components of Allium macrostemon. From the chromatograms of "Antagonist 1", "Antagonist 2", "Decoction 1", "Decoction 2", and "Decoction 3", it can be seen that both the negative solution and the sample solution contain a large number of components that interfere with the fluorescent spots in the "Allium macrostemon" solution.

In the chromatogram, the Allium macrostemon solution shows a bright fluorescent spot, but the sample solution contains too many interfering components, which interfere with the development of these secondary components.

[0271] From Figure 14 it can be seen that the elution effect of a single packing chromatography column is not good.

[0315] Depend on Figure 18 It can be seen that the processing method provided in Comparative Example 13 failed the methodological verification and contained a lot of impurities, which affected the fluorescent spots of Allium macrostemon.
[0316] Comparative Example 14
[0317] Allium macrostemon ether extract solution: Take 4g of Allium macrostemon powder (YF210101), add 100ml of water, boil for 10 minutes, cool, filter, and extract the filtrate twice with 20ml of ether each time. Combine the ether extracts, evaporate to dryness, and dissolve the residue in 1ml of ethyl acetate to obtain the Allium macrostemon ether extract solution (hereinafter referred to as "ether extract" solution). Collect the aqueous solution for later use.
[0318] Residual solution of the ether extract of Baihe Rhizoma Allii Macrostemonis: The residual water solution of the ether extract was evaporated on a water bath, and the residue was dissolved in 2 ml of methanol to obtain the residual solution of the ether extract of Baihe Rhizoma Allii Macrostemonis (referred to as "ether residual" solution).
[0319] Ethyl acetate extract solution of Baihe Rhizoma Allii Macrostemonis: 4 g of Baihe Rhizoma Allii Macrostemonis powder (YF210101) was added to 100 ml of water, boiled for 10 minutes, cooled, filtered, and the filtrate was extracted with ethyl acetate twice, 20 ml each time. The ethyl acetate extract solution was combined, evaporated, and the residue was dissolved in 1 ml of ethyl acetate to obtain the ethyl acetate extract solution of Baihe Rhizoma Allii Macrostemonis (referred to as "ethyl acetate extract" solution). The water solution was collected for later use.
[0320] Residual solution of the ethyl acetate extract of Baihe Rhizoma Allii Macrostemonis: The residual water solution of the ethyl acetate extract was evaporated on a water bath, and the residue was dissolved in 2 ml of methanol to obtain the residual solution of the ethyl acetate extract of Baihe Rhizoma Allii Macrostemonis (referred to as "ethyl acetate residual" solution).
[0321] n-Butanol extract solution of Baihe Rhizoma Allii Macrostemonis: 4 g of Baihe Rhizoma Allii Macrostemonis powder (YF210101) was added to 100 ml of water, boiled for 10 minutes, cooled, filtered, and the filtrate was extracted with n-butanol twice, 20 ml each time. The n-butanol extract solution was combined, evaporated, and the residue was dissolved in 1 ml of methanol to obtain the n-butanol extract solution of Baihe Rhizoma Allii Macrostemonis (referred to as "n-butanol extract" solution). The water solution was collected for later use.
[0322] Residual solution of the n-butanol extract of Baihe Rhizoma Allii Macrostemonis: The residual water solution of the n-butanol extract was evaporated on a water bath, and the residue was dissolved in 2 ml of methanol to obtain the residual solution of the n-butanol extract of Baihe Rhizoma Allii Macrostemonis (referred to as "n-butanol residual" solution).
[0323] Ten microliters of each of the "ether extract" solution, the "ethyl acetate extract" solution, the "n-butanol extract" solution, the "ether residual" solution, the "ethyl acetate residual" solution, and the "n-butanol residual" solution were taken and spotted on the same silica gel G thin layer plate. Ethyl acetate-methanol (1:1) was used as the developing agent, and the plate was developed, taken out, dried, sprayed with 10% sulfuric acid ethanol solution, heated at 105°C until the spots were clearly colored, and observed under daylight and ultraviolet light (365 nm).
[0324] The results are shown in Figure 19 , Figure 19 The chromatogram obtained by using the developing agent ethyl acetate-methanol (1:1) provided for Comparative Example 14. Figure 19 In the figure, the left graph is the chromatogram under daylight, and the right graph is the chromatogram under ultraviolet (365 nm) observation. Among them, from left to right, the samples are the "ether extract" solution, the "ethyl acetate extract" solution, the "n-butanol extract" solution, the "ether residual" solution, the "ethyl acetate residual" solution, and the "n-butanol residual" solution.
[0325] Depend on Figure 19 It can be seen that among the six Allium macrostemon solutions, the n-butanol-extracted solution showed more fluorescent components, but the developing solvent ethyl acetate-methanol (1:1) did not separate these components well.
[0326] Take 10 μl of each of the following six solutions: "ether extract", "ethyl acetate extract", "n-butanol extract", "ether residue", "ethyl acetate residue", and "n-butanol residue", and spot them separately on the same silica gel G thin-layer plate. Develop the plate using n-hexane-ethyl acetate (1:1) as the developing solvent. Remove the plate, air dry it, spray it with 10% sulfuric acid ethanol solution, and heat it at 105℃ until the spots are clearly visible. Examine the plate under sunlight and ultraviolet light at 365 nm.
[0327] See results Figure 20 , Figure 20 The chromatogram obtained using the developing solvent n-hexane-ethyl acetate (1:1) provided for Comparative Example 14. Figure 20 The left image shows the chromatogram under sunlight, and the right image shows the chromatogram under ultraviolet (365nm) examination. From left to right, the samples are: ether extract, ethyl acetate extract, n-butanol extract, ether residue, ethyl acetate residue, and n-butanol residue.
[0328] Depend on Figure 20 It can be seen that among the six Allium macrostemon solutions, only the n-butanol-extracted solution had a single fluorescent spot, but this spot was too close to the starting point.
[0329] Comparative Example 15
[0330] The sample was obtained using the same sample processing method as Comparative Example 14.
[0331] Take 10 μl each of the following six solutions: ether extract, ethyl acetate extract, n-butanol extract, residual ether extract, residual ethyl acetate extract, and residual n-butanol extract. Spot each solution onto the same silica gel G thin-layer plate. Develop the plate using ethyl acetate as the developing solvent. Remove the plate, air dry it, spray it with 10% sulfuric acid ethanol solution, and heat it at 105°C until the spots are clearly visible. Examine the plate under sunlight and ultraviolet light at 365 nm.
[0332] See results Figure 21 , Figure 21 The chromatogram obtained using ethyl acetate as the developing solvent for Comparative Example 15. Figure 21 The left image shows the chromatogram under sunlight, and the right image shows the chromatogram under ultraviolet (365nm) examination. From left to right, the samples are: ether extract, ethyl acetate extract, n-butanol extract, ether residue, ethyl acetate residue, and n-butanol residue.
[0333] It can be seen that the first three solutions have fluorescent spots, which are in a suitable position, but the spots are relatively blurred. Figure 21
[0334] Comparative Example 16
[0335] The sample was obtained according to the sample processing method of Comparative Example 14.
[0336] Ten μl of each of the "ethyl ether extract" solution, the "ethyl acetate extract" solution, the "n-butanol extract" solution, the "ethyl ether residue" solution, the "ethyl acetate residue" solution and the "n-butanol residue" solution was spotted on the same silica gel G thin layer plate, and developed with methanol as the developing agent. After taking out, air-drying, spraying with 10% sulfuric acid ethanol solution and heating at 105°C until the spots were clearly colored, the plate was observed under daylight and ultraviolet light 365 nm.
[0337] The results are shown in Figure 22 , Figure 22 The chromatogram obtained by using methanol as the developing agent for Comparative Example 16. Figure 22 The left graph is the chromatogram under daylight, and the right graph is the chromatogram under ultraviolet (365 nm) observation. Among them, from left to right, the samples are the "ethyl ether extract" solution, the "ethyl acetate extract" solution, the "n-butanol extract" solution, the "ethyl ether residue" solution, the "ethyl acetate residue" solution and the "n-butanol residue" solution.
[0338] It can be seen that the last four solutions all have fluorescent spots, but the spots are too close to the front, and the developing agent needs to be further adjusted. Figure 22
[0339] Comparative Example 17
[0340] The sample was obtained according to the sample processing method of Comparative Example 14.
[0341] Ten μl of each of the "ethyl ether extract" solution, the "ethyl acetate extract" solution, the "n-butanol extract" solution, the "ethyl ether residue" solution, the "ethyl acetate residue" solution and the "n-butanol residue" solution was spotted on the same silica gel G thin layer plate, and developed with ethyl acetate-glacial acetic acid-formic acid-water (15:1:1:2) as the developing agent. After taking out, air-drying, spraying with 10% sulfuric acid ethanol solution and heating at 105°C until the spots were clearly colored, the plate was observed under daylight and ultraviolet light 365 nm.
[0342] The results are shown in Figure 23 , Figure 23 The chromatogram obtained by using ethyl acetate-glacial acetic acid-formic acid-water (15:1:1:2) as the developing agent for Comparative Example 17. Figure 23 The left image shows the chromatogram under sunlight, and the right image shows the chromatogram under ultraviolet (365nm) examination. From left to right, the samples are: ether extract, ethyl acetate extract, n-butanol extract, ether residue, ethyl acetate residue, and n-butanol residue.
[0343] Depend on Figure 23 It can be seen that there are many fluorescent spots in the "ethyl acetate extract" solution and the separation is good, indicating that the developing solvent ethyl acetate-glacial acetic acid-formic acid-water (15:1:1:2) is good for separating the Allium macrostemon herb solution.
[0344] Comparative Example 18
[0345] The sample was obtained using the same sample processing method as in Comparative Example 8.
[0346] Take 5 μl of each of the three solutions, namely "Xie-Yang-1", "An-Yang-1" and "Tang-Yang-1", and spot them separately on the same silica gel G thin-layer plate. Use ethyl acetate-methanol-water (15:4:2) as the developing solvent, develop, remove, air dry, spray with 10% sulfuric acid ethanol solution, and heat at 105℃ until the spots are clearly visible. Examine under sunlight and ultraviolet light at 365 nm.
[0347] See Figure 24 , Figure 24 The chromatogram obtained using the developing solvent ethyl acetate-methanol-water (15:4:2) provided for Comparative Example 18. Figure 24 In the image, the left image shows the chromatogram under sunlight, and the right image shows the chromatogram under ultraviolet (365nm) examination. From left to right, the samples are "Allium-Oxygen-1" solution, "Anion-Oxygen-1" solution, and "Ton-Oxygen-1" solution.
[0348] Depend on Figure 24 It can be seen that the developing solvent ethyl acetate-methanol-water (15:4:2) is not good at separating the Allium macrostemon component in the decoction of Citrus aurantium, Allium macrostemon and Cinnamomum cassia.
[0349] Take 5 μl of each of the three solutions, namely "Xan-O-1", "An-O-1" and "Tang-O-1", and spot them separately on the same silica gel G thin-layer plate. Use ethyl acetate-methanol-0.1% sodium hydroxide (15:4:2) as the developing solvent, develop, remove, air dry, spray with 10% sulfuric acid ethanol solution, and heat at 105℃ until the spots are clearly visible. Examine under sunlight and ultraviolet light at 365 nm.
[0350] See Figure 25 , Figure 25 The chromatogram obtained using the developing solvent ethyl acetate-methanol-0.1% sodium hydroxide (15:4:2) provided for Comparative Example 17. Figure 25In the image, the left image shows the chromatogram under sunlight, and the right image shows the chromatogram under ultraviolet (365nm) examination. From left to right, the samples are "Allium-Oxygen-1" solution, "Anion-Oxygen-1" solution, and "Ton-Oxygen-1" solution.
[0351] Depend on Figure 25 It can be seen that the developing solvent ethyl acetate-methanol-0.1% sodium hydroxide (15:4:2) is not good at separating the Allium macrostemon component in the Zhishi Xiebai Guizhi Decoction.
[0352] Comparative Example 19
[0353] Samples were obtained according to the sample preparation methods of Example 1 and Comparative Example 12.
[0354] Four solutions (10 μl each) were taken from the method validation specificity test: Allium macrostemon control herb solution (121130-202107, batch number of Allium macrostemon control herb: 121130-202107), negative solution for Allium macrostemon lacking in Zhishi Allium macrostemon and Cinnamon Twig Decoction (21042802), test solution 21031601 (i.e. decoction of Zhishi Allium macrostemon and Cinnamon Twig Decoction (21031601)), and "Decoction 2" solution. They were spotted onto the same silica gel G thin-layer plate. Three plates were spotted using the same method. The developing solvents were ethyl acetate-methanol-water (15:4:2), ethyl acetate-methanol-10% acetic acid (15:4:2), and ethyl acetate-methanol-0.1% sodium hydroxide (15:4:2), respectively. After development, the plates were removed, dried, sprayed with 10% sulfuric acid ethanol solution, and heated at 105℃ until the spots were clearly visible. The spots were then examined under a UV lamp at 365 nm.
[0355] See Figure 26 , Figure 26 Chromatograms obtained using three different developing solvents provided for Comparative Example 19. Figure 26 In the figures, the developing solvent in the left figure is ethyl acetate-methanol-water, the developing solvent in the middle figure is ethyl acetate-methanol-10% acetic acid, and the developing solvent in the right figure is ethyl acetate-methanol-0.1% sodium hydroxide. From left to right, the samples in the figures are: Allium macrostemon control solution, Allium macrostemon negative solution, test solution 21031601, and "Tang 2" solution.
[0356] Depend on Figure 26 It can be seen that the developing solvent ethyl acetate-methanol-water (15:4:2) did not develop the target spot. The developing solvent ethyl acetate-methanol-10% acetic acid (15:4:2) separated the Allium macrostemon component in the Zhi Shi Xie Bai Gui Zhi Tang decoction in the sample relatively well, but it was too close to the impurity spots, indicating room for improvement. The two test solutions of Zhi Shi Xie Bai Gui Zhi Tang decoction with the developing solvent ethyl acetate-methanol-0.1% sodium hydroxide (15:4:2) did not show the target fluorescent spot due to uneven spraying of the developing solvent.
[0357] Comparative Example 20
[0358] The sample was prepared according to the sample preparation method of Example 1 and Comparative Example 12.
[0359] Ten μl of the Allium tuberosum control drug material solution (121130-202107), the negative solution without Allium tuberosum in the Allium tuberosum, Fructus Aurantii and Ramulus Cinnamomi Decoction, the test sample solution 21031601, the "Decoction 1" solution and the "Decoction 2" solution were taken and spotted on the same silica gel G thin layer plate. Two plates were spotted in the same way and developed with ethyl acetate-methanol-0.1% sodium hydroxide (15:4:2) and ethyl acetate-methanol-water (15:4:2) respectively. The developed plates were taken out, dried, sprayed with 10% sulfuric acid ethanol solution and heated at 105°C until the spots were clearly colored. The plates were observed under ultraviolet light at 365 nm.
[0360] Reference is made to Figure 27 , Figure 27 The chromatograms obtained using two different developing agents provided for Comparative Example 20. Figure 27 In the figure, the developing agent for the left plate is ethyl acetate-methanol-0.1% sodium hydroxide and the developing agent for the right plate is ethyl acetate-methanol-water. From left to right in the figure, the samples are the Allium tuberosum control drug material solution, the negative solution without Allium tuberosum, the test sample solution 21031601 and the "Decoction 2" solution.
[0361] As can be seen from Figure 27 , both developing agents are suitable. There is no fluorescent spot of the Allium tuberosum component in the "Decoction 1" solution. The test sample solution (21031601) and the "Decoction 2" solution both have fluorescent spots of the Allium tuberosum component. However, the separation of the test sample solution (21031601) is obviously better and the spots are brighter, while the spots in the "Decoction 2" solution are dimmer, possibly interfered by impurity components.
[0362] Comparative Example 21
[0363] The sample was prepared according to the sample preparation method of Comparative Example 12.
[0364] Ten μl of the "Decoction 2" solution was taken and spotted on a silica gel G thin layer plate. Three plates were spotted in the same way and developed with ethyl acetate-methanol-formic acid-water (8:1:1:1), toluene-glacial acetic acid-water (7.5:10:0.3) and n-butanol-ethanol-glacial acetic acid-water (4:1:2:1) respectively. The developed plates were taken out, dried, sprayed with 10% sulfuric acid ethanol solution and heated at 105°C until the spots were clearly colored. The plates were observed under ultraviolet light at 365 nm.
[0365] Reference is made to Figure 28 , Figure 28 The chromatograms obtained using three different developing agents provided for Comparative Example 21. Figure 28The developing agent of the left picture is ethyl acetate-methanol-formic acid-water, the developing agent of the middle picture is toluene-glacial acetic acid-water, and the developing agent of the right picture is n-butanol-ethanol-glacial acetic acid-water.
[0366] It can be seen that the three developing agents above cannot separate the components of the "Tang 2" solution. Figure 28
[0367] Comparative Example 22
[0368] The sample was prepared according to the sample preparation method of Comparative Example 12.
[0369] 10 μl of the "Tang 2" solution was taken and spotted on a silica gel G thin layer plate, and three plates were spotted in the same way. The lower layer solution was developed with chloroform-ethyl acetate-methanol-water (15:40:22:10) at 10°C below, the upper layer solution was developed with n-butanol-ethyl acetate-water (4:1:5), and the upper layer solution was developed with n-butanol-acetic acid-water (3:2:1). After development, the plate was taken out, dried, sprayed with 10% sulfuric acid ethanol solution, heated at 105°C until the spots were clearly colored, and observed under a UV light lamp at 365 nm.
[0370] Reference is made to Figure 29 , Figure 29 The chromatograms obtained by the three different developing agents provided for Comparative Example 22. Figure 29 The developing agent of the left picture is chloroform-ethyl acetate-methanol-water, the developing agent of the middle picture is n-butanol-ethyl acetate-water, and the developing agent of the right picture is n-butanol-acetic acid-water.
[0371] It can be seen that the three developing agents above cannot separate the components of the "Tang 2" solution. Figure 29
[0372] Comparative Example 23
[0373] The sample was prepared according to the sample preparation method of Example 1 and Comparative Example 12.
[0374] 10 μl of each of the Baijiangqian Guizhi Tang solution without Baijiangqian (21042802), the test sample solution (21031601), the "Tang 2" solution, and the Baijiangqian control drug material solution (121130-202107) in the method validation specificity were taken and spotted on the same silica gel G thin layer plate. The developing agent was chloroform-ethyl acetate-methanol-water (15:40:22:10). After development, the plate was taken out, dried, sprayed with 10% sulfuric acid ethanol solution, heated at 105°C until the spots were clearly colored, and observed under a UV light lamp at 365 nm.
[0375] Reference is made to Figure 30 , Figure 30 The chromatogram obtained using the developing solvent chloroform-ethyl acetate-methanol-water (15:40:22:10) provided for Comparative Example 23. Figure 30 In the middle, from left to right, the samples are: Allium macrostemon control solution, Allium macrostemon negative solution, test sample solution (21031601), and "Tang 2" solution.
[0376] Depend on Figure 30 It can be seen that the developing solvent chloroform-ethyl acetate-methanol-water (15:40:22:10) is not good at separating the Allium macrostemon components in Zhishi Xiebai Guizhi Decoction.
[0377] Comparative Example 24
[0378] Samples were obtained according to the sample preparation methods of Example 1 and Comparative Example 12.
[0379] Take 10 μl of each of the following four solutions from the method validation specificity test: Allium macrostemon control solution (121130-202107), negative solution for Allium macrostemon lacking in Zhishi Xiebai Guizhi Decoction (21042802), test solution (21031601), and "Tang 2" solution. Spot them on the same silica gel G thin-layer plate. Spot three plates in the same way. Use ethyl acetate-methanol-water (10:2:1), ethyl acetate-methanol-0.1% sodium hydroxide (10:2:1), and ethyl acetate-methanol-10% acetic acid (10:2:1) as developing solvents, respectively. Remove the plates, air dry them, spray them with 10% sulfuric acid ethanol solution, heat them at 105℃ until the spots are clearly visible, and examine them under a UV lamp at 365 nm.
[0380] See Figure 31 , Figure 31 Chromatograms obtained using the three developing solvents provided in Comparative Example 24. Figure 31 In the diagram, the left image shows ethyl acetate-methanol-water, the middle image shows ethyl acetate-methanol-0.1% sodium hydroxide, and the right image shows ethyl acetate-methanol-10% acetic acid. Figure 31 In the middle, from left to right, the samples are: Allium macrostemon control solution, Allium macrostemon negative solution, Zhishi Allium macrostemon and Cinnamon Twig Decoction (21031601), and "Decoction 2" solution.
[0381] Depend on Figure 31 It can be seen that the developing solvents ethyl acetate-methanol-water (10:2:1) and ethyl acetate-methanol-0.1% sodium hydroxide (10:2:1) are good at separating the Allium macrostemon components in Zhishi Xiebai Guizhi Decoction, while the developing solvent ethyl acetate-methanol-10% acetic acid (10:2:1) is poor at separation.
[0382] Comparative Example 25
[0383] The sample was obtained according to the sample preparation method of Comparative Example 13.

Spot them separately on the same 0.1% sodium hydroxide silica gel G thin-layer plate. Develop the plate with ethyl acetate-methanol-water (10:2:1). Remove the plate, air dry it, spray it with 10% sulfuric acid ethanol solution, and heat it at 105℃ until the spots are clearly visible. Examine the plate under a UV lamp at 365 nm.
[0385] See Figure 32 , Figure 32 The chromatogram obtained using the developing solvent ethyl acetate-methanol-water (10:2:1) provided for Comparative Example 25. Figure 32 In the middle, from left to right, the samples are blank solution, Allium macrostemon control solution, Allium macrostemon positive solution, Zhishi Allium macrostemon and Cinnamon Twig Decoction without Allium macrostemon negative solution, and Zhishi Allium macrostemon and Cinnamon Twig Decoction decoction (21060201, 21060202, 21060203).
[0386] Depend on Figure 32 It can be seen that the developing solvent ethyl acetate-methanol-water (10:2:1) is not good at separating the Allium macrostemon components in Zhishi Xiebai Guizhi Decoction.
[0387] Comparative Example 26
[0388] The sample was obtained according to the sample preparation method of Comparative Example 13.
[0389] Take 10 μl of each of the following seven solutions: blank solution, Allium macrostemon control solution (121130-202107), Allium macrostemon positive solution, Zhishi Xiebai Guizhi Tang (Zhishi Xiebai Guizhi Tang) negative solution (21042802), and Zhishi Xiebai Guizhi Tang decoction (21060201, 21060202, 21060203), and spot them on the same silica gel G thin-layer plate. Develop the plate using ethyl acetate-methanol-ammonia water (10:2:1) as the developing solvent. Remove the plate, air dry it, spray it with 10% sulfuric acid ethanol solution, and heat it at 105℃ until the spots are clearly visible. Examine the plate under a UV lamp at 365 nm.
[0390] See Figure 33 , Figure 33 The chromatogram obtained using the developing solvent ethyl acetate-methanol-ammonia (10:2:1) provided for Comparative Example 26. Figure 33 In the middle, from left to right, the samples are blank solution, Allium macrostemon control solution, Allium macrostemon positive solution, Zhishi Allium macrostemon and Cinnamon Twig Decoction without Allium macrostemon negative solution, and Zhishi Allium macrostemon and Cinnamon Twig Decoction decoction (21060201, 21060202, 21060203).
[0391] Depend on Figure 33It can be seen that the developing solvent ethyl acetate-methanol-ammonia (10:2:1) is not good at separating the Allium macrostemon components in Zhishi Xiebai Guizhi Decoction.
[0392] Comparative Example 27
[0393] The sample was obtained according to the sample preparation method of Comparative Example 13.
[0394] Take 10 μl of each of the following seven solutions: blank solution, Allium macrostemon control solution (121130-202107), Allium macrostemon positive solution, Zhi Shi Xie Bai Gui Zhi Tang (Zhi Shi Xie Bai Gui Zhi Tang) negative solution (21042802), and Zhi Shi Xie Bai Gui Zhi Tang decoction (21060201, 21060202, 21060203). Spot each solution onto the same silica gel G thin-layer plate. Spot three plates using the same method. Develop the plates using ethyl acetate-methanol-water (10:2:1), ethyl acetate-methanol-0.1% sodium hydroxide (10:2:1), and ethyl formate-methanol-water-ammonia (10:2:1:0.1), respectively. Remove the plates, air dry them, spray them with 10% sulfuric acid ethanol solution, and heat them at 105℃ until the spots are clearly visible. Examine them under a UV lamp at 365 nm.
[0395] See Figure 34 , Figure 34 Chromatograms obtained using the three developing solvents provided in Comparative Example 27. Figure 34 In the middle figure, the developing solvent in the left figure is ethyl acetate-methanol-water, the developing solvent in the middle figure is ethyl acetate-methanol-0.1% sodium hydroxide, and the developing solvent in the right figure is ethyl formate-methanol-water-ammonia.

[0396] Depend on Figure 34 It can be seen that the developing solvent ethyl acetate-methanol-water (10:2:1) separates the components of Allium macrostemon well, but the negative solution has fluorescent spots of the same color at the target spot position. The other two developing solvents have poor development effects.
[0397] Comparative Example 28

[0470] The following samples were tested using the proposed thin-layer chromatography method under different spotting conditions: Allium macrostemon reference material solution (121130-202107), negative sample solution of Zhishi Allium macrostemon and Cinnamon Twig Decoction (21042802), and decoction of Zhishi Allium macrostemon and Cinnamon Twig Decoction (21031601, 21042801, 21051001). The results for 5 μl and 15 μl samples are as follows.
[0471] See results Figure 54 , Figure 54 Chromatograms of different spotting amounts provided in Example 2. Figure 54 In the middle, from left to right, are the Allium macrostemon control solution, negative solution, and decoction of Citrus aurantium, Allium macrostemon and Cinnamomum cassia (21031601, 21042801, 21051001) (all 5 μl); Allium macrostemon control solution, negative solution, and decoction of Citrus aurantium, Allium macrostemon and Cinnamomum cassia (21031601, 21042801, 21051001) (all 15 μl).
[0472] The results showed that when the sample volume was 10 μl, the fluorescent spots of the reference solution and the test solution on the silica gel G plate were clearly visible, while when the sample volume was 5 μl, the fluorescent spots of the test solution on the silica gel G plate were dimmer and difficult to observe.
[0473] Example 3 - Validation of Thin-Layer Chromatography Identification Method (Method 1)
[0474] Method 1: The thin-layer chromatographic identification method for the decoction of Zhi Shi Xie Bai Gui Zhi Tang is as follows:
[0475] Take 100 ml of sample and extract twice with n-butanol, 30 ml each time. Combine the n-butanol extracts, evaporate to dryness, dissolve the residue in 5 ml of methanol, and pass the solution through a neutral alumina column (100-200 mesh, 3 g, inner diameter 1.5 cm). Elute with 20 ml of methanol, discard the eluent, and then elute with 25 ml of water. Collect the eluent and pass it through a D101 macroporous adsorption resin column (inner diameter 1.5 cm, column length 10 cm). Elute sequentially with 25 ml of water, 25 ml of 10% methanol, 25 ml of 50% methanol, and 25 ml of methanol. Collect the methanol eluent, recover the solvent to dryness, and dissolve the residue in 1 ml of methanol to obtain the sample solution.
[0476] According to the above thin-layer chromatography method (General Chapter 0502 of the Chinese Pharmacopoeia), 10 μl of the above solution was applied separately to the same silica gel G thin-layer plate. Ethyl acetate-formic acid-glacial acetic acid-water (15:1:1:2) was used as the developing solvent. The plate was developed, removed, and dried. It was then sprayed with 10% sulfuric acid ethanol solution and heated at 105°C until the spots were clearly visible. The plates were then examined under ultraviolet light (365 nm).
[0477] In accordance with the relevant requirements of the "Guiding Principles for Validation of Analytical Methods for Drug Quality Standards" in General Chapter 9101 of the Chinese Pharmacopoeia, the thin-layer chromatography identification method 1 for Allium macrostemon in the reference sample of Zhishi Xiebai Guizhi Decoction was validated. Specificity and robustness tests showed that this method is robust to thin-layer identification using Allium macrostemon as a reference standard.
[0478] 1. Exclusivity
[0479] Allium macrostemon decoction (positive sample, batch number: 21042803), Allium macrostemon and Cinnamomum cassia decoction (negative sample lacking Allium macrostemon, batch number: 21042802), and Allium macrostemon and Cinnamomum cassia decoction (reference sample, batch numbers: 21031601, 21042801, 21051001) were prepared according to the standard decoction process.
[0480] Take appropriate amounts of pure water (blank sample), reference sample, negative sample, positive sample, and Allium macrostemon (batch number: 121130-202107) as reference materials, and prepare the test solution and control solution according to the thin-layer chromatography method described in Method 1 above. Take the above solutions and perform identification experiments according to the proposed thin-layer identification method. The results are shown in [Figure 1]. Figure 55 .
[0481] Figure 55 This is a specificity result diagram provided for Example 3. Figure 55 In the middle, from left to right, are: blank, Allium macrostemon control material (batch number: 121130-202107), negative sample of Zhi Shi Xie Bai Gui Zhi Tang without Allium macrostemon (batch number: 21042802), Allium macrostemon decoction (positive sample, batch number: 21042803), and Zhi Shi Xie Bai Gui Zhi Tang decoction (reference samples: 21031601, 21042801, 21051001).
[0482] The results showed that the control sample, the positive sample, and the three batches of reference samples all had a fluorescent spot of the same color at the same location. The blank solution did not have a fluorescent spot of the same color at this location, and the negative solution did not have a significant fluorescent spot of the same color at this location. This indicates that the method has good specificity for identifying reference samples.
[0483] 2. Durability
[0484] (1) Thin-layer boards from different manufacturers
[0485] Thin-layer chromatography plates produced by Qingdao Hailang Silica Gel Desiccant Co., Ltd. and Qingdao Ocean Chemical Plant Branch (see specificity results figure) were used. After activation treatment, the following samples were taken: Allium macrostemon reference solution (121130-202107), negative sample of Zhishi Allium macrostemon and Cinnamon Twig Decoction lacking Allium macrostemon (batch number: 21042802), and decoction of Zhishi Allium macrostemon and Cinnamon Twig Decoction (reference samples, batch numbers: 21031601, 21042801, 21051001). The results of Qingdao Hailang plates are shown in the figure. Figure 56 .
[0486] Figure 56 Images showing the results of thin-layer laminates from different manufacturers. Figure 56 In the middle, from left to right, are the control material of Allium macrostemon, the negative solution, and the decoction of Citrus aurantium, Allium macrostemon and Cinnamomum cassia (reference samples: 21031601, 21042801, 21051001).
[0487] The results showed that different brands of silica gel G plate did not show significant difference in the identification of the method, indicating that the method was suitable for different brands of silica gel plate.
[0488] (2) Different humidity
[0489] Considering that the results of thin-layer identification experiments are often affected by temperature and humidity, the humidity conditions that may occur in the laboratory in different seasons were investigated. Relative humidity of 32%, 65%, and 88% were selected for research. The Baijiang decoction of Fructus Aurantii, Bulbus Allii Macrostemonis, and Ramulus Cinnamomi (reference samples: 21031601, 21042801, 21051001) were investigated under the proposed thin-layer chromatography at three different humidity conditions, and the results are shown in Figure 57 .
[0490] Figure 57 The thin-layer chromatography identification results under different relative humidity. Figure 57 In the above figures, from left to right are Baijiang decoction of Fructus Aurantii, Bulbus Allii Macrostemonis, and Ramulus Cinnamomi (reference samples: 21031601, 21042801, 21051001). Figure 57
[0491] The results showed that the thin-layer identification results under different humidity conditions could be reproduced, indicating that the method was not sensitive to humidity and had good environmental humidity resistance.
[0492] (3) Temperature
[0493] The study continued to investigate the temperature that may occur in the laboratory in different seasons, and refrigerators (about 5°C) and room temperature (about 25°C, see specificity chromatogram) were selected for research. Baijiang decoction of Fructus Aurantii, Bulbus Allii Macrostemonis, and Ramulus Cinnamomi (reference samples: 21031601, 21042801, 21051001) were investigated under the proposed thin-layer chromatography at different temperature conditions, and the low-temperature development results are shown in Figure 58 .
[0494] Figure 58 The thin-layer chromatography identification results under low-temperature temperature. Figure 58 In the above figures, from left to right are Baijiang decoction of Fructus Aurantii, Bulbus Allii Macrostemonis, and Ramulus Cinnamomi (reference samples: 21031601, 21042801, 21051001).
[0495] The results showed that the thin layer identification results at different temperatures had no difference, and the reproducibility was good, indicating that the method had good temperature tolerance.
[0496] (4) Spotting volume
[0497] The specific method can be seen in Example 2. The results showed that a spotting volume of 10 μl could ensure that the fluorescence spots in the chromatogram were clear and distinguishable, so the spotting volume of the Allium bakeri component thin layer chromatography identification was selected to be 10 μl.
[0498] In the robustness experiment, the effects of different brands of silica gel G plates, different temperatures, humidities and different spotting volumes on the identification results were investigated. The comparison test of different spotting volumes determined that the optimal spotting volume was 10 μl. It was found that other factors had good reproducibility, and the reference sample test solution showed the same colored spots at the corresponding positions of the Allium bakeri control drug material chromatogram, indicating that the method had good robustness.
[0499] Example 4 - Methodology verification (Method 2)
[0500] According to the relevant requirements of the "Guiding Principles for the Verification of Analysis Methods for Drug Quality Standards" of the Chinese Pharmacopoeia 9101, the Allium bakeri component thin layer chromatography identification method 2 of the reference sample of Zhishixi Allium bakeri Guizhi Decoction was verified. The specificity and robustness test showed that the method had poor specificity and robustness for thin layer identification using Allium bakeri control drug material as the control drug material.
[0501] The specific verification process is as follows:
[0502] Method 2 is as follows:
[0503] Take 100 ml of sample solution and pass it through a D101 macroporous adsorption resin column (inner diameter 1.5 cm, column length 10 cm). Elute with water 100 ml, 10% methanol 50 ml, 50% methanol 100 ml and methanol 50 ml, respectively. Collect the methanol eluate, recover the solvent to dryness, add 1 ml of methanol to dissolve the residue, and use it as the sample solution.
[0504] According to the thin layer chromatography method (Chinese Pharmacopoeia General 0502), take 10 μl of the above solution and spot it on the same silica gel G thin layer plate. Use ethyl acetate-methanol-ammonia water-water (10:2:0.02:1) as the developing agent, develop, take out, air dry, spray with 10% sulfuric acid ethanol solution, heat at 105°C until the spots are clearly colored, and observe under ultraviolet light (365 nm).
[0505] 1 Specificity
[0506] The Baijiu decoction (positive sample, batch number: 21060301), negative decoction of Ciguizhi decoction without Baijiu (negative sample, batch number: 21042802), and Ciguizhi decoction (reference sample, batch numbers: 21060201, 21060202, and 21060203) were prepared according to the standard decoction process. Appropriate amounts of water, reference sample, negative sample, positive sample, and Baijiu control medicinal materials (batch number: 121130-202107) were taken to prepare the test sample solution and control solution according to the proposed thin layer chromatography method. The above solutions were taken and subjected to identification experiments according to the proposed thin layer identification method. The results are shown in Figure 59 .
[0507] Figure 59 The specificity results of Example 4 are shown in the figure. Figure 59 From left to right in the figure are blank, Baijiu control medicinal materials, positive solution, negative solution, and Ciguizhi decoction (reference samples 21060201, 21060202, and 21060203).
[0508] The results show that the Baijiu control medicinal materials, Baijiu positive sample, and 3 batches of reference samples have a fluorescent spot of the same color at the same position. The blank solution has no fluorescent spot of the same color at this position, and the negative solution has no obvious fluorescent spot of the same color at this position. However, the negative sample has a relatively obvious fluorescent band with background color from the starting point to the solvent front. This indicates that the method has poor specificity for identifying reference samples.
[0509] 2. Durability
[0510] (1) Thin layer plates from different manufacturers
[0511] Thin layer chromatography plates produced by Qingdao Hailang Silica Gel Drier Co., Ltd. and Qingdao Marine Chemical Factory Branch (see the specificity results figure) were selected and activated. Baijiu control medicinal materials, negative solution, and Ciguizhi decoction (reference samples: 21060201, 21060202, and 21060203) were determined according to the proposed thin layer chromatography method. The results of Qingdao Hailang plates are shown in Figure 59 . Figure 59 The chromatogram of the thin layer plate is a Qingdao Hailang plate. Figure 59 From left to right in the figure are Baijiu control medicinal materials, negative solution, and Ciguizhi decoction (reference samples: 21060201, 21060202, and 21060203).
[0512] (2) Different humidity
[0513] Considering that the results of thin-layer identification experiments are often affected by temperature and humidity, the humidity conditions that may occur in the laboratory in different seasons were investigated, and relative humidity of 32%, 65%, and 88% were selected for research. The Baihe reference materials, negative solution, and Zhishixie Baihe Guizhi Decoction (benchmark samples: 21060201, 21060202, and 21060203) were investigated under the proposed thin-layer chromatography at three different humidity conditions, and the results are shown in Figure 60 and Figure 61 , Figure 60 and Figure 61 are the thin-layer chromatography identification results under different relative humidity. Among them, Figure 60 and Figure 61 are two repeated tests, Figure 61 is the retest result. Figure 60 and Figure 61 , the left graph is the thin-layer chromatography identification result under relative humidity of 88%, the middle graph is the thin-layer chromatography identification result under relative humidity of 65%, and the right graph is the thin-layer chromatography identification result under relative humidity of 32%. Figure 60 and Figure 61 In each graph, from left to right are Baihe reference materials, negative solution, and Zhishixie Baihe Guizhi Decoction (benchmark samples: 21031601, 21042801, and 21051001).
[0514] The results show that the thin-layer identification results under different humidity environments cannot be reproduced, indicating that this method is not suitable for humidity investigation.
[0515] (3) Temperature
[0516] The study continued to investigate the temperature that may occur in the laboratory in different seasons, and the refrigerator (about 5°C) and room temperature (about 25°C, see specificity chromatogram) were selected for research. The Baihe reference materials, negative solution, and Zhishixie Baihe Guizhi Decoction (benchmark samples: 21060201, 21060202, and 21060203) were investigated under the proposed thin-layer chromatography at different temperature conditions, and the low-temperature development results are shown in Figure 62 . Figure 62 is the thin-layer chromatography identification result under low temperature. Figure 62 In the graph, from left to right are Baihe reference materials, negative solution, and Zhishixie Baihe Guizhi Decoction (benchmark samples: 21060201, 21060202, and 21060203).
[0517] The results show that under low temperature, the test solution does not show the same color fluorescent spots at the same position as the Baihe reference material solution, indicating that the method is not suitable for low temperature conditions.
[0518] (4) Sample size
[0519] Comparing different sample application amounts, 5 μl, 10 μl and 15 μl were selected for comparative study (10 μl see the specificity chromatogram). The Baijianggui Decoction (reference samples: 21060201, 21060202 and 21060203) was taken as the sample, and the negative solution and the control Allium bakeri were taken as the samples. The Baijianggui Decoction (reference samples: 21060201, 21060202 and 21060203) was taken as the sample, and the negative solution and the control Allium bakeri were taken as the samples. The results of 5 μl and 15 μl are shown in Figure 63 . Figure 63 The identification results of different sample application amounts of thin layer chromatography. Figure 63 In the above figures, the left graph is the identification result of 5 μl sample application amount of thin layer chromatography, and the right graph is the identification result of 15 μl sample application amount of thin layer chromatography. Figure 63 In the above figures, the left graph is the identification result of 5 μl sample application amount of thin layer chromatography, and the right graph is the identification result of 15 μl sample application amount of thin layer chromatography.
[0520] In the durability experiment, the effects of different brands of silica gel G plates, different temperatures, humidities and different sample application amounts on the identification results were investigated. The comparative test of different sample application amounts determined that the optimal sample application amount was 10 μl. It was found that other factor tests could not reproduce the method, indicating that the method had poor durability.
[0521] Comparative Example 36
[0522] 1. Preparation of sample
[0523] 1.1 Preparation of the Baijianggui Decoction test solution: 50 ml of the Baijianggui Decoction extract (21060203) (equivalent to 1.7 g of Allium bakeri) was taken, 3 ml of hydrochloric acid was added, heated for reflux for 1 hour, cooled, and extracted with ethyl acetate twice, 30 ml each time. The ethyl acetate liquid was combined and concentrated to 5 ml to serve as the Baijianggui Decoction test solution.
[0524] 1.2 Preparation of the Allium bakeri test solution: 1.5 g of Allium bakeri (YF210101) was taken, finely ground, 50 ml of water and 3 ml of hydrochloric acid were added, heated for reflux for 1 hour, cooled, and extracted with ethyl acetate twice, 30 ml each time. The ethyl acetate liquid was combined and concentrated to 5 ml to serve as the Allium bakeri test solution.
[0525] 1.3 Preparation of the Allium bakeri control solution: 1.5 g of the Allium bakeri control (121130-202107) was taken, finely ground, 50 ml of water and 3 ml of hydrochloric acid were added, heated for reflux for 1 hour, cooled, and extracted with ethyl acetate twice, 30 ml each time. The ethyl acetate liquid was combined and concentrated to 5 ml to serve as the Allium bakeri control solution.
[0526] 2. Process of thin layer identification:
[0527] 2 μl of the test sample solution and 1 μl of the control medicinal material were spotted on the same silica gel G thin layer plate, developed with petroleum ether (60-90 °C)-ethyl acetate-dichloromethane-formic acid (5:3.5:1:0.8) as the developing agent, taken out, dried, and observed under a 365 nm ultraviolet light.
[0528] 3 Results and analysis
[0529] See Figure 64 , Figure 64 The chromatogram obtained by the detection method provided for Comparative Example 36. It can be seen from Figure 64 that the Baishu medicinal material and the Baishu control medicinal material have a same color fluorescent spot at the same position, indicating that the patent is suitable for identifying the Baishu medicinal material. The Zhishibaibaiguizhitou decoction and the Baishu control medicinal material have a spot at the same position of the main fluorescent spot, but the color of the spot is lighter, and the brightness of the main fluorescent spot of the Baishu control medicinal material is too different, and it is not easy to distinguish whether the spot is the same yellow-green color as the main fluorescent spot. Therefore, the thin layer chromatography identification of the Zhishibaibaiguizhitou decoction Baishu medicinal flavor in Comparative Example 36 is not practical.
[0530] The above only describes the preferred embodiments of the present application, and it should be noted that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the protection scope of the present application.
