Technical Field
[0001] This invention relates to the field of pharmaceutical technology, specifically to a method for constructing characteristic spectra or fingerprint spectra of a tonifying and blood-activating preparation or intermediate, and its application. Background Technology
[0002] Chronic liver disease is a long and complex condition, but from a Traditional Chinese Medicine (TCM) perspective, it is mainly caused by the body's infection with pathogenic factors, leading to a struggle between the body's resistance and the pathogenic factors. If the body's resistance is weak, it cannot expel the pathogenic factors, resulting in a prolonged and intractable disease. The basic pathogenesis is a coexistence of deficiency and excess. The deficiency mainly involves both Qi and Yin deficiency, while the excess involves heat accumulation and dampness, blood stasis and obstruction of the collaterals, resulting in Qi and Yin deficiency and the retention of damp-heat and pathogenic factors internally. From a Western medical perspective, liver fibrosis refers to the pathological process of abnormal proliferation of fibrous connective tissue in the liver when hepatocytes undergo necrosis and inflammation. The vast majority of chronic liver diseases involve liver fibrosis, which is the most important pathological feature of chronic liver disease. Liver fibrosis and cirrhosis are related but distinct. Pathologically, diffuse fibrosis alone is called liver fibrosis, while diffuse liver fibrosis accompanied by destruction of the liver lobule structure is cirrhosis. From a pathogenesis perspective, liver fibrosis is a pre-cirrhotic lesion and is reversible, while cirrhosis is the result of further development of liver fibrosis. Clinical observations show that liver fibrosis and cirrhosis are a continuous process. Liver fibrosis generally does not lead to liver dysfunction, but it can cause portal hypertension. Liver fibrosis is a repair process following liver injury, causing changes in the amount and composition of the liver's extracellular matrix (ECM).
[0003] Liver fibrosis is an inevitable pathological process in the progression of various chronic liver diseases to cirrhosis. Finding drugs to prevent, delay, or even reverse liver fibrosis is an urgent problem to be solved in liver disease research. For a long time, traditional Chinese medicine has played an important role in combating liver fibrosis. Traditional Chinese medicine believes that liver fibrosis involves both blood stasis and deficiency of vital energy; therefore, strengthening the body's resistance and removing blood stasis is an important treatment principle. Fuzheng Huayu Capsules (tablets) are specifically formulated to address the "internal stagnation of blood and deficiency of vital energy" in chronic hepatitis, liver fibrosis, and cirrhosis. Based on repeated pharmacological studies, the formula is composed of drugs that invigorate blood circulation, remove blood stasis, and nourish essence and replenish deficiency. Among them, Danshen (Salvia miltiorrhiza) invigorates blood circulation and removes blood stasis, serving as the principal drug; Cordyceps mycelium nourishes deficiency and replenishes essence; Peach kernel removes blood stasis and breaks up stagnation, serving as the assistant drug; Pine pollen nourishes and disperses liver stagnation; Gynostemma pentaphyllum clears heat and detoxifies, serving as the adjuvant drug; and Schisandra chinensis, with its sour and warm properties, nourishes the liver, serving as the guiding drug. Pharmacological experiments have shown that this compound preparation has the effects of anti-liver fibrosis, reducing portal pressure, protecting hepatocytes, reducing lipid peroxidation damage, regulating immune function, and reducing liver inflammation. Clinical trials have verified that this tonifying and stasis-removing preparation can achieve a liver fibrosis stage transformation rate of 52%–58.3%, therefore, it has a significant therapeutic effect on decompensated liver cirrhosis.
[0004] Fuzheng Huayu preparations are composed of six herbs: Danshen, fermented Cordyceps militaris powder, peach kernel, pine pollen, Gynostemma pentaphyllum, and Schisandra chinensis. They have the effect of treating liver, lung, and kidney fibrosis. Currently, there are two dosage forms on the market: (1) Fuzheng Huayu capsules: obtained the National New Drug Certificate of China in 2002 (National Drug Certificate No. Z20020053) and approved the National Drug Standard WS3-459(Z-79)-2005(Z); (2) Fuzheng Huayu tablets: obtained the National New Drug Certificate of China in 2005 (National Drug Certificate No. Z20050564) and approved the National Drug Standard YBZ19332005-2009Z. The preparations for strengthening the body and removing blood stasis are mainly used for hepatitis B liver fibrosis belonging to the syndrome of blood stasis obstructing the collaterals and liver and kidney deficiency. Symptoms include lumps under the ribs, pain in the ribs, sallow complexion, or red streaks of erythema, soreness and weakness of the waist and knees, fatigue, dizziness and blurred vision, dark red tongue or ecchymosis, thin or slightly yellow coating, and wiry and thready pulse.
[0005] Currently, there are no literature reports on a comprehensive analysis of the chemical composition of Fuzheng Huayu dry paste powder, or on the study of its characteristic spectral or fingerprint spectral characteristics. Summary of the Invention

[0226] 2.1 Selection of Indicator Peaks
[0227] Based on the chemical composition analysis results of the Fuzheng Huayu dry paste powder using liquid chromatography-mass spectrometry (LC-MS), and considering the peak area and specificity of each component, compounds with good absorption under ultraviolet light were prioritized while also taking into account the attribution of all chromatographic peaks. Twelve index peaks for method development were selected, as shown in Table 2.

[0230] 2.2 Preparation method of test solution - Selection of extraction solvent
[0231] Different extraction solvents (water, methanol, 50% methanol, 80% methanol, 50% ethanol, 70% ethanol, anhydrous ethanol) were investigated. Two samples were prepared in parallel for each extraction solvent. The number of chromatographic peaks at 210 nm and the peak area / sample weight value of the index peak were calculated. The samples were prepared according to the following method:
[0232] Take approximately 0.5g of the powder, accurately weigh it, and place it in a 50ml stoppered conical flask. Accurately add 25ml of different extraction solvents, seal tightly, weigh, and sonicate (300W power, 40kHz frequency) for 30 minutes. Cool, weigh again, and replenish the lost weight with the corresponding solvent. Shake well, centrifuge at 12000rpm for 5 minutes, and take the supernatant.
[0233] Accurately pipette 1 μl of the test solution and inject it into the liquid chromatograph for determination.
[0234] The experimental results and analysis show that the number of peaks at 210 nm from anhydrous ethanol extraction is significantly lower than that from other solvent extractions, while there is no significant difference in the number of peaks at 210 nm among the other six solvents. The peak area of the index peaks from anhydrous ethanol extraction is significantly lower than that from other solvent extractions, so it is not considered. The peak areas of index peaks 11 and 12 from water extraction are significantly lower than those from the other five extraction solvents, so they are not considered. The peak area of index peak 5 from methanol extraction is significantly lower than that from the other four extraction solvents, so it is not considered. The total peak areas of the index peaks from 70% ethanol, 50% ethanol, 80% methanol, and 50% methanol extractions are roughly the same. Considering the overall profile and peak shape of some chromatographic peaks from 50% methanol extraction (e.g., RT = 2–6 min), 50% methanol is selected as the extraction solvent for preparing the test solution of the Fuzheng Huayu dry paste powder.
[0235] 2.3 Preparation method of test solution - Selection of extraction method
[0236] The extraction methods (heating reflux, ultrasonic extraction, and warm maceration) were investigated. Two samples were prepared in parallel for each extraction method. The number of chromatographic peaks at 210 nm and the peak area / sample weight value of the index peak were calculated. The samples were prepared as follows:
[0237] Heating under reflux: Weigh approximately 0.5g of the powder accurately and place it in a 100ml round-bottom flask. Add 25ml of 50% methanol accurately, seal tightly, weigh, and heat under reflux for 1 hour. Cool, replenish the lost weight with 50% methanol solution, shake well, centrifuge at 12000rpm for 5 minutes, and collect the supernatant.
[0238] Ultrasonic extraction: Weigh approximately 0.5g of the powder accurately and place it in a 50ml stoppered conical flask. Add 25ml of 50% methanol accurately, seal tightly, weigh, and ultrasonically extract for 1 hour. Cool, replenish the lost weight with 50% methanol solution, shake well, centrifuge at 12000rpm for 5 minutes, and collect the supernatant.
[0239] Warm soaking: Weigh approximately 0.5g of the powder accurately and place it in a 50ml stoppered conical flask. Add 25ml of 50% methanol accurately, seal tightly, weigh, and soak in a 50℃ water bath for 4 hours. Cool, replenish the lost weight with 50% methanol solution, shake well, centrifuge at 12000rpm for 5 minutes, and collect the supernatant.
[0240] Accurately pipette 1 μl of the test solution and inject it into the liquid chromatograph for determination.
[0241] Experimental results showed no significant difference in the number of peaks and peak area of the index peaks at 210 nm when using different extraction methods. Considering all factors, ultrasonic extraction was chosen as the extraction method for the test sample.
[0242] 2.4 Preparation method of test solution - Selection of extraction time
[0243] The extraction times were examined (15 min, 30 min, 45 min, 60 min). Two samples were prepared in parallel for each extraction time. The number of chromatographic peaks at 210 nm and the peak area / sample weight value of the index peak were calculated. The samples were prepared according to the following method:
[0244] Accurately weigh approximately 0.5g of the powder and place it in a 50ml stoppered conical flask. Accurately add 25ml of 50% methanol, seal tightly, and weigh. Extract using ultrasound (300W power, 40kHz frequency) for different times (15min, 30min, 45min, 60min). Cool, replenish the lost weight with 50% methanol, shake well, centrifuge at 12000rpm for 5min, and collect the supernatant.
[0245] The results showed no significant difference in the number of peaks and peak area at 210 nm when different extraction times were used. Considering all factors, 15 min was selected as the extraction time for the test sample.
[0246] 2.5. Preparation method of test solution - Investigation of solid-liquid ratio
[0247] The material-liquid ratios (1:100, 1:50, 1:20) were investigated. Two samples were prepared in parallel for each material-liquid ratio. The peak area of the index at 210 nm was calculated as a percentage of the sample weight. The samples were prepared according to the following method:
[0248] Material-to-liquid ratio 1:100: Weigh approximately 0.25g of the powder accurately and place it in a 50ml stoppered conical flask. Accurately add 25ml of 50% methanol, seal tightly, weigh, and extract ultrasonically (300W power, 40kHz frequency) for 15min. Cool, replenish the lost weight with 50% methanol, shake well, centrifuge at 12000rpm for 5min, and collect the supernatant.
[0249] Material-liquid ratio 1:50: Take about 0.5g of the powder, accurately weigh it, and put it into a 50ml stoppered conical flask. Accurately add 25ml of 50% methanol, seal tightly, weigh, and extract ultrasonically (power 300W, frequency 40kHz) for 15min. Cool, replenish the lost weight with 50% methanol, shake well, centrifuge at 12000rpm for 5min, and take the supernatant.
[0250] Material-to-liquid ratio 1:20: Weigh approximately 1.25g of the powder accurately and place it in a 50ml stoppered conical flask. Accurately add 25ml of 50% methanol, seal tightly, weigh, and extract ultrasonically (300W power, 40kHz frequency) for 15min. Cool, replenish the lost weight with 50% methanol, shake well, centrifuge at 12000rpm for 5min, and collect the supernatant.
[0251] Accurately pipette 1 μl of the test solution and inject it into the liquid chromatograph for determination.
[0252] Experimental results showed no significant difference in extraction efficiency between different solid-liquid ratios, indicating that the extraction solvent was not saturated with the main compounds in the sample. Therefore, a solid-liquid ratio of 1:50 was ultimately selected as the optimal extraction ratio for the test sample.
[0253] 2.6 Test Solution Preparation Method—Filtration Method Investigation
[0254] Different filtration methods were investigated (high-speed centrifugation, filtration with microporous membranes of different pore sizes: 0.22 μm and 0.45 μm). Two samples were prepared in parallel for each filtration method. The number of chromatographic peaks at 210 nm, the peak area / sample weight ratio, resolution, tailing factor, and theoretical plate number were calculated. The samples were prepared according to the following method:
[0255] Accurately weigh approximately 0.5g of the powder and place it in a 50ml stoppered conical flask. Accurately add 25ml of 50% methanol, seal tightly, weigh, and extract using ultrasonic extraction (300W power, 40kHz frequency) for 15 minutes. Cool, replenish the lost weight with 50% methanol, shake well, and use three different filtration methods (high-speed centrifugation, 0.22μm and 0.45μm filter membranes). Collect the supernatant / filtrate to obtain the product.
[0256] Accurately pipette 1 μl of the test solution and inject it into the liquid chromatograph for determination.
[0257] Experimental results showed that under the same conditions, there was no significant difference in the number of peaks obtained by the three filtration methods. There was also no significant difference in the resolution, tailing factor, and theoretical plate number. However, considering that the filter membrane has a certain adsorption effect on the index peaks 5, 6, 7 and 8, centrifugation was finally chosen as the filtration method for the test solution of the Fuzheng Huayu dry paste powder.
[0258] 2.7 Determination of the preparation method for the test solution
[0259] Through optimization of the above-mentioned test sample solution preparation method, the final determined test sample solution preparation method is as follows:
[0260] Take approximately 0.5 g of the test sample, accurately weigh it, and place it in a 50 ml stoppered conical flask. Accurately add 25 ml of 50% methanol, seal the flask tightly, weigh it, and extract it by sonication (300 W power, 40 kHz frequency) for 15 min. Cool the flask, replenish the lost weight with 50% methanol, shake well, centrifuge at 12000 rpm for 5 min, and collect the supernatant.
[0261] 2.8 Optimization of Chromatographic Conditions - Wavelength Selection
[0262] Prepare the test solution according to the method for preparing the test solution, and examine the wavelengths (254nm, 210nm, 280nm, 330nm), and calculate the number of chromatographic peaks and the peak area / sample weight value of the index peak.
[0263] The results showed that the number of chromatographic peaks was highest and the overall peak response was highest at 210 nm. The number of chromatographic peaks of the test sample was significantly less at 330 nm than at the other three wavelengths; the number of chromatographic peaks was roughly the same at 254 nm and 280 nm, but the overall response was lower than that at 210 nm. Considering all factors, 210 nm was selected as the wavelength for optimizing the chromatographic conditions of the fingerprint spectrum of the Fuzheng Huayu dry paste powder.
[0264] 2.9 Optimization of Chromatographic Conditions—Column Investigation
[0265] Different chromatographic columns were examined, with column numbers and models shown in Table 4. Two samples were prepared for each column in parallel, and the number of peaks, peak area / sample weight of the index peak, resolution, tailing factor, and theoretical plate number were calculated. The results are shown in Tables 5 to 9.
[0266] Because some chromatographic columns cannot tolerate pure aqueous phase, the mobile phase gradient was appropriately modified, as shown in Table 3.

[0283]
[0284] Experimental results showed that under the same conditions, column 4 had poor peak shape at RT = 30–32 min and was not considered. Because some of the index peaks had low responses, to prevent low reproducibility, peak selection should focus on these components. Index peak 7 had low responses in columns 2 and 6 and was not considered. Columns 1, 3, and 5 showed little difference under these analytical conditions, but considering the poor peak shape and resolution of highly polar components with earlier retention times, columns with good resistance to aqueous phases should be selected; therefore, column 5 was not considered. Taking all factors into account, Waters ACQUITY was chosen. HSS T3 (column 1) and Waters Further investigation was conducted using column T3 (column 3). The results are shown in Tables 10 to 14.

[0296]
[0297] The results show that, under the same conditions, Waters ACQUITY HSS T3 (column 1) and Waters There was no significant difference in the number of peaks at T3 (column 3); further considering the low responses of peaks 3, 4, 7, and 8, and taking into account the reproducibility of the method, a column with a higher response was selected; taking into account resolution, tailing factor, theoretical plate number, and overall peak shape, Waters ACQUITY was ultimately chosen. HSS T3 (column 1) is a column with optimized chromatographic conditions for fingerprinting.
[0298] 2.10 Optimization of Chromatographic Conditions—Investigation of Mobile Phase System
[0299] Different mobile phase systems (methanol-water, acetonitrile-water system) were investigated. Two samples were prepared in parallel for each mobile phase system, and the overall peak shape, retention time and other factors of the chromatograms were compared.
[0300] Experimental results show that the elution capacity is stronger in the acetonitrile system, and the cutoff wavelength of acetonitrile is lower than that of methanol. Since 210 nm was used as the fingerprint spectrum acquisition wavelength in this study, the acetonitrile-water system was selected as the mobile phase system for fingerprint chromatographic conditions.
[0301] 2.11 Optimization of Chromatographic Conditions—Investigation of Mobile Phase Additives
[0302] Different mobile phase additives (formic acid, acetic acid, phosphoric acid, ammonium formate) were investigated. The types of mobile phase additives are shown in Table 15. Two samples were prepared for each mobile phase additive, and the number of peaks at 210 nm, peak area / sample weight, resolution, tailing factor, and theoretical plate number were calculated. The results are shown in Tables 16 to 20.

[0315]
[0316]
[0317] Experimental results show that, under the same conditions, there is no significant difference in the number of peaks among different mobile phase additives. When ammonium formate is used as an additive, the peak areas of indexes 5, 6, and 7 are lower than those of the other three additives, so they are not considered. When acetic acid and phosphoric acid are used as mobile phase additives, indexes 1 and 5 are significantly higher than those of the other two additives. Considering that formic acid and acetic acid are prone to causing uneven baselines when used as additives, phosphoric acid is selected as the mobile phase additive after comprehensive consideration.
[0318] 2.12 Optimization of Chromatographic Conditions—Investigation of Mobile Phase Additive Concentration
[0319] Different mobile phase additive concentrations (0.02% phosphoric acid-water, 0.05% phosphoric acid-water, 0.1% phosphoric acid-water) were investigated. Two samples were prepared in parallel for each mobile phase additive concentration. The number of peaks at 210 nm and the peak area / sample weight value, resolution, tailing factor, and theoretical plate number were calculated.
[0320] Experimental results showed that, under the same conditions, there was no significant difference in the number and area of peaks with different concentrations of additives. Considering the pH tolerance of the chromatographic column, 0.05% phosphoric acid was selected as the mobile phase additive.
[0321] 2.13 Optimization of Chromatographic Conditions—Column Temperature Study
[0322] The study investigated different column temperatures (25℃, 30℃, 35℃), with two samples prepared in parallel at each column temperature. The number of peaks at 210 nm and the peak area / sample weight, resolution, tailing factor, and theoretical plate number were calculated.
[0323] Experimental results showed that under the same conditions, there was no significant difference in the number of peaks at the three column temperatures. By comparing factors such as resolution, tailing factor, theoretical plate number, and peak shape, 30℃ was selected as the optimal column temperature for fingerprint chromatographic conditions.
[0324] 2.14 Optimization of Chromatographic Conditions—Flow Rate Investigation
[0325] Different flow rates (0.30 ml / min, 0.35 ml / min, 0.40 ml / min) were investigated. Two samples were prepared in parallel for each flow rate. The number of peaks at 210 nm and the peak area / sample weight, resolution, tailing factor, and theoretical plate number were calculated.
[0326] Experimental results showed that there was no significant difference in the number of peaks at different flow rates; the sum of peak areas was largest at 0.30 ml / min. Considering factors such as resolution, tailing factor, and theoretical plate number, 0.30 ml / min was selected as the flow rate for fingerprint chromatographic conditions.
[0327] 2.15. Optimization of Chromatographic Conditions—Injection Volume Investigation
[0328] Different injection volumes (0.5 μl, 1 μl, 2 μl, 5 μl) were investigated. Two samples were prepared in parallel for each injection volume. The number of peaks at 210 nm and the peak area / sample volume, resolution, tailing factor, and theoretical plate number were calculated.
[0329] Experimental results show that, under the same conditions, some index peaks have low responses at an injection volume of 0.5 μl, so they are not considered; the baseline is uneven at RT = 13-16 min when the injection volume is 2 μl and 5 μl; and the first index peak is saturated at an injection volume of 5 μl. By comparing the resolution, tailing factor, theoretical plate number, and overall peak shape, 1 μl was finally selected as the injection volume for the fingerprint chromatographic conditions.

[0338]
[0339] Experimental results show that, under the same conditions, when using mobile phase gradient 1, the chromatographic peaks are not completely eluted, which may affect the next injection, and the chromatographic peak resolution is poor. When using mobile phase gradient 2, the baseline is uneven from RT to 14 to 16 min, and the chromatographic peak resolution is poor. When using mobile phase gradient 3, the baseline is more stable from RT to 13 to 16 min, and the chromatographic peak resolution is good. Furthermore, by comparing the overall peak shape, the peak shape of mobile phase gradient 3 is significantly better than that of mobile phase gradients 1 and 2. Finally, mobile phase gradient 3 was selected as the elution gradient for the fingerprint chromatographic conditions.

[0346] 3.2 Fingerprint Similarity Evaluation
[0347] The 2012 version of the "Traditional Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System" software was used to import data from 27 batches of Fuzheng Huayu dry paste powder test samples into the software. The data processing time range was set to 1-42 minutes, and the parameters were set as follows: the reference chromatogram number was S14, the reference chromatogram generation method was the mean method, and the time window width was 0.1 minutes.
[0348] A common peak refers to a chromatographic peak that has the same relative retention time within a certain comparison time window. After peak position correction to match the chromatographic peaks, 18 common peaks were selected based on the chromatographic data of the Fuzheng Huayu dry paste powder test sample. The results of the common peak identification are shown in Table 24.
[0349] Finally, the fingerprint spectrum (R) of the Fuzheng Huayu dry ointment powder was obtained (e.g.) Figure 2 As shown in the figure, 18 common peaks were marked in the control fingerprint spectrum. The similarity between each batch of Fuzheng Huayu dry powder and the control fingerprint spectrum was calculated using software. The results showed that the similarity was greater than 0.90, which is good and meets the technical requirements of fingerprint spectrum.
