Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine, and in particular to a method, a device and a storage medium for identifying the leaf-down ratio grade of a moxibustion material. Background Art

[0002] The light and heat stimulation of moxibustion, mainly the physiological changes caused by heat, is the key factor in exerting its clinical therapeutic effect. Therefore, the good heat release performance of moxa burning is the basic guarantee for its therapeutic effect and an important basis for the evaluation of moxa quality. In previous research reports, the research on moxa has focused on the microstructure identification of the composition of moxa substances and the research on indicators such as smoke composition, temperature, and heat. For example, the "Qi moxa grading quality standard" uses the non-main component of moxa 0.14mm 2 The number of leaf pulp fragments under the moxa is divided into three grades, lacking the quality evaluation of the non-glandular hairs that are the main components of moxa. Peng Zheng et al. used nitrogen content as an evaluation index and believed that the higher the grade of moxa, the lower the nitrogen content. Zhang Yuan used TG / DSC, TG-FTIR and IR to study and found that the infrared wavelength of infrared radiation released by moxa is basically consistent with the wavelength of human radiation. The ignition, burnout and comprehensive combustion performance of moxa are close to woody and better than herbs. Its combustion heat release parameters are closely related to the content of cellulose, hemicellulose and lignin; CAO et al. used TG to study and found that the ignition temperatures of lignin, hemicellulose and cellulose are 405℃, 370℃ and 410℃ respectively. Although these studies have focused on the intrinsic thermal properties of moxa, they have not conducted in-depth discussions on the quality control evaluation methods of moxa with different specifications and grades of leaf velvet. In other words, in the prior art, there is no scientific quality identification method that can clarify the scientific connotation of the quality composition and heat production of moxibustion velvet, that is, the leaf velvet ratio grade identification method.

[0047] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present invention. Brief Description of the Drawings

[0054] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are only examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0055] Example 1

[0056] Figure 1 is a schematic flowchart of a method for identifying the leaf - fluff ratio grade of a moxibustion material shown according to an exemplary embodiment. As Figure 1 shown, the method includes:

[0057] S1. Obtain the cellulose content of the moxa fluff with an unknown leaf - fluff ratio by the differential weight method;

[0058] S2. Obtain the microscopic image of mature non - glandular hairs through a microscope, and obtain the length of non - glandular hairs by performing image analysis on the microscopic image;

[0059] S3. Comprehensively obtain the leaf - fluff ratio of the moxa fluff according to which preset standard value range of cellulose content of the leaf - fluff ratio the cellulose content is closest to or within, and according to which preset standard value range of the length of non - glandular hairs of the leaf - fluff ratio the length of non - glandular hairs is closest to or within;

[0060] It can be understood that TG / DSC is an effective technical method for studying thermal decomposition, which can quantitatively measure thermal analysis parameters such as mass loss, decomposition rate, sample heat flow change, combustion peak temperature (Tp), maximum mass loss rate (Rp), heat, etc. during the combustion and pyrolysis process. Professional image analysis software can observe the two - dimensional and three - dimensional stereoscopic structures of non - glandular hairs in moxa fluff. The combination of the two for analysis can elaborate the correlation between the microscopic morphology, geometric features of the sample and the macroscopic thermal analysis parameters, which helps to reveal the scientific connotation of heat release during the combustion of moxa fluff of different specifications and grades. Therefore, this application conducts research on the heat - release quality of the microscopic and macroscopic aspects of the main source of moxa fluff - non - glandular hairs. It intends to analyze the variation law of the length of non - glandular hairs of moxa fluff with different leaf - fluff ratios by using a microscope and professional image analysis software, and study the changes in the contents of cellulose, hemicellulose and lignin in moxa fluff by the Van Soest method. Use thermogravimetry / differential scanning calorimetry (TG / DSC) to conduct a correlation study to characterize the combustion pyrolysis parameters of moxa fluff with different leaf - fluff ratios. Finally, use the Pearson correlation coefficient method to conduct a correlation analysis on the parameters studied above, aiming to reveal the correlation and influence relationship and quality change law between the microscopic quality composition of non - glandular hairs of moxa fluff with different leaf - fluff ratios and moxibustion heat, clarify the scientific connotation of the quality composition and heat generation of moxa fluff, and establish a new objective and controllable quality evaluation method;

[0061] The cellulose content of the moxa fluff with an unknown leaf - fluff ratio is obtained by the differential weight method. It should be noted that for how to obtain the cellulose content by the differential weight method, it is already a quite mature existing technology, and this application will not elaborate too much on it. Then, the microscopic image of mature non - glandular hairs is obtained through a microscope, and the length of non - glandular hairs is obtained by performing image analysis on the microscopic image. It should be noted that the microscopic identification methods for mature and complete non - glandular hairs include:

[0062] A physical adhesion method for observing the maturity of epidermal hairs of moxibustion materials: The plastic transparent tape is a common type of tape, cut into 1 cm × 1 cm rectangular pieces with scissors. Use tweezers to gently adhere the 1 cm × 1 cm rectangular piece to the back of the leaf, so that the non-glandular hairs are adhered to the rectangular piece, make a specimen, and observe with a microscope;

[0063] A physical separation method for observing the maturity of epidermal hairs of moxibustion materials: Take different Artemisia argyi samples, clean and dry them in the shade, put them into self-sealing bags and seal for later use. Weigh the dried Artemisia argyi with an electronic balance respectively, and then use a multi-functional crusher to crush each Artemisia argyi sample 3 times at intervals. After each crushing for 2 minutes, sieve through a No. 1 sieve once, then crush and sieve again. The last time, sieve through a No. 2 sieve. Take a small amount of moxibustion material, put it into a plastic test tube, and then add a small amount of dilute glycerol (prepared by taking 33 ml of glycerol and distilled water and configuring with a 100 ml volumetric flask). After checking that the centrifuge tube is sealed well, physically shake it for 3 min - 15 min. Use a pipette to suck a small amount of liquid, drop it on a clean glass slide, and cover it with a cover slip. Measure the length and width at different magnifications of the microscope. When taking points, try to ensure that as many complete non-glandular hairs as possible can be measured when measuring the length, and use image analysis software to calculate and measure the geometric data (length and width) of the non-glandular hairs. Generally, the length of mature non-glandular hairs is 500 - 1500 μm, and the width is 1 - 15 μm;

[0064] It should be emphasized that in the above process, the moxibustion material is the moxibustion material after being crushed by a multi-functional crusher; The non-glandular hair density of Artemisia argyi is relatively large. Take a small amount of moxa floss and add dilute glycerol, and physically shake it for about 5 min - 20 min; The non-glandular hair density of Herba Diclipterae is relatively small, and the sampling amount is 2 times that of Artemisia argyi floss. Add dilute glycerol and physically shake it for about 5 - 20 min; The preparation of dilute glycerol requires preparation and use immediately to reduce the occurrence of reagent contamination;

[0065] After obtaining the length of the non-glandular hairs and the content of microelements of the moxa floss with an unknown leaf-floss ratio through the above method, compare them with the standard value range of cellulose of the preset leaf-floss ratio and the standard value range of the length of non-glandular hairs of the preset leaf-floss ratio, so as to determine the leaf-floss ratio of the moxa floss.

[0066] Preferably,

[0067] The acquisition of the standard value range of cellulose of the preset leaf-floss ratio and the standard value range of the length of non-glandular hairs of the preset leaf-floss ratio includes:

[0068] Obtain the contents of cellulose, hemicellulose and lignin of moxa floss with different known leaf-floss ratios by the differential weight method respectively;

[0069] Microscopic images of mature non-glandular hairs of moxa floss with known different leaf fluff ratios are obtained through a microscope. By performing image analysis on the microscopic images, the lengths and widths of the non-glandular hairs of moxa floss with different leaf fluff ratios are obtained;

[0070] The moxa floss with known different leaf fluff ratios is burned, and various combustion indexes of the moxa floss with different leaf fluff ratios are obtained by acquiring combustion data;

[0071] Calculate the comprehensive contribution rates of the contents of cellulose, hemicellulose, and lignin, the lengths and widths of non-glandular hairs of the moxa floss with known different leaf fluff ratios to various combustion indexes. According to the comprehensive contribution rates, it is obtained that the comprehensive contribution degrees of the lengths of non-glandular hairs and the content of cellulose of the moxa floss with different leaf fluff ratios to various combustion indexes are the highest;

[0072] According to the lengths of non-glandular hairs and the content of cellulose of the moxa floss with known different leaf fluff ratios, the standard value ranges of the lengths of non-glandular hairs with different leaf fluff ratios and the standard value ranges of cellulose with different leaf fluff ratios are obtained;

[0073] It can be understood that the process of obtaining the standard value range of cellulose with a preset leaf fluff ratio and the standard value range of the length of non-glandular hairs with a preset leaf fluff ratio includes:

[0074] The moxa floss with known different leaf fluff ratios, in this embodiment, taking Artemisia argyi and Artemisia stolonifera (Jilin) as examples, is as follows in the table:

[0075]

[0076]

[0077] Artemisia argyi:

[0078] Accurately weigh 60.0 grams of dry leaves, put them into a pulverizer for pulverization, sieve once every 1 minute during pulverization, weigh and record the experimental data. Process and prepare moxa floss with different leaf fluff ratios of 3:1, 5:1, 10:1, and 15:1 in this way. In the same way, prepare 3 samples for each leaf fluff ratio. Use professional image analysis software to measure the lengths and widths of non-glandular hairs, and measure the lengths and widths of natural non-glandular hairs at leaf fluff ratios of 3:1, 5:1, 10:1, and 15:1 respectively. The results are as follows in the table:

[0079] Microscopic characteristics of non-glandular hairs of each grade of Artemisia argyi moxa floss (N = 300)

[0080]

[0081] According to the Van Soest method in the literature, the neutral detergent fiber, acid detergent fiber, acid-insoluble lignin and ash of moxa floss with different leaf fluff ratios were determined, and the cellulose, hemicellulose and lignin contents were calculated by the differential weight method, as shown in the following table:

[0082] Physicochemical property indexes of graded Qiai floss

[0083]

[0084]

[0085] Weigh about 7 mg of moxa floss and put it into an Al2O3 crucible of a synchronous thermal analyzer (TG / DSC). Set the programmed temperature range from 28 to 900 °C, the heating rate is 10 °C / min, the reaction gas is oxygen, and the flow rate is 20 mL / min. The combustion parameters of the sample are calculated as shown in the following table:

[0086] Combustion parameter property indexes of graded Qiai floss

[0087]

[0088] DSC combustion parameter property indexes of graded Qiai floss

[0089]

[0090]

[0091] The experimental research results show that the cellulose content of moxa floss and the length-width ratio of non-glandular hairs (1-20) are both significantly positively correlated with the ignition temperature (Ti), ignition time (ti), and heat (J2), while the cellulose content is significantly negatively correlated with the peak temperature (Tp) and peak time (tp) of combustion, and the length-width ratio of non-glandular hairs (20-40) is significantly negatively correlated with the burnout temperature (Tb), burnout time (tb), and total heat of combustion (J). The above results indicate that as the leaf fluff ratio increases, the spatial skeleton of non-glandular hairs in moxa floss becomes shorter, the cellulose content increases, and there is a close correlation between combustion dynamic parameters, which can provide a new evaluation method for the quality evaluation of moxa floss with different leaf fluff ratios;

[0092] As attached Figure 2As shown in the figure, through the identification method of "non-glandular hair - cellulose - TG / DSC", it is found that the Artemisia argyi floss with different leaf - fluff ratios has the following changing rules. The lengths of non - glandular hairs with leaf - fluff ratios between 3:1, 5:1, 10:1, and 15:1 are 542.46, 303.24, 291.18, 220.69, and 170.61 μm respectively. The cellulose contents with leaf - fluff ratios between 3:1, 5:1, 10:1, and 15:1 are 19.37, 30.40, 38.94, 45.38, and 49.40% respectively. The ignition index (Di), combustibility index (C), burnout index (Db), and comprehensive combustion index (S) of TG / DSC between leaf - fluff ratios of 3:1, 5:1, 10:1, and 15:1 show a significant increasing trend, which can provide a new "non - glandular hair - cellulose - TG / DSC" evaluation method for the quality evaluation of Artemisia argyi floss with different leaf - fluff ratios;

[0093] Then, Artemisia stolonifera is used to verify the above conclusion:

[0094] Accurately weigh 60.0 grams of dry leaves of Artemisia stolonifera, put them into a pulverizer for pulverization, sieve once every 1 minute of pulverization, weigh and record the experimental data, and process and prepare Artemisia argyi floss with different leaf - fluff ratios of 3:1, 5:1, 10:1, and 15:1 in this way. For each leaf - fluff ratio sample, 3 copies are prepared in the same way. Measure the length of non - glandular hairs with professional image - analysis software, and measure the length and width of non - glandular hairs of Artemisia argyi floss with leaf - fluff ratios of 3:1, 5:1, 10:1, and 15:1 respectively. As shown in the following table:

[0095] Microscopic characteristics of non - glandular hairs of each grade of Artemisia stolonifera floss (N = 300)

[0096]

[0097] According to the Van Soest method in the literature, determine the neutral detergent fiber, acid detergent fiber, acid - insoluble lignin, and ash of Artemisia argyi floss with different leaf - fluff ratios, and calculate the contents of cellulose, hemicellulose, and lignin by the difference - weight method. As shown in the following table:

[0098] Physicochemical property indexes for grading Artemisia stolonifera floss

[0099]

[0100]

[0101] Weigh about 7 mg of Artemisia argyi floss (Artemisia stolonifera), put it into an Al2O3 crucible of a synchronous thermal analyzer (TG / DSC), set the programmed temperature - rising range from 28 to 900 °C, the heating rate is 10 °C / min, the reaction gas is oxygen, and the flow rate is 20 mL / min. Calculate the combustion parameters of the sample. As shown in the following table:

[0103]

[0104] Combustion Parameter Property Indexes of Artemisia stolonifera (Matsum.) H. Lév. (Moxa Floss)

[0105]

[0106]

[0107] As shown in the Figure 3 appendix, through the identification method of "non-glandular hair - cellulose - TG / DSC", it is found that Artemisia stolonifera moxa floss with different leaf fluff ratios also has the following variation rules. The natural non-glandular hairs on the leaves, and the lengths of non-glandular hairs between the leaf fluff ratios of 3:1, 5:1, 10:1, and 15:1 are 812.45, 461.92, 293.83, 249.38, and 197.22 μm respectively. The cellulose contents between the leaves, 3:1, 5:1, 10:1, and 15:1 leaf fluff ratios are 15.82, 28.16, 32.95, 43.14, and 47.36% respectively. The ignition index (Di), combustibility index (C), burnout index (Db), and comprehensive combustion index (S) of TG / DSC between the leaf fluff ratios of 3:1, 5:1, 10:1, and 15:1 also show an increasing trend;

[0108] Based on the above data, for the lengths, length-width ratios, cellulose, hemicellulose, and lignin of non-glandular hairs of moxa floss with different leaf fluff ratios, SPSS is used to calculate the cumulative variance contribution rates of each factor to the ignition index (Di), combustibility index (C), burnout index (Db), and comprehensive combustion index (S). The results show that the contribution degree of the non-glandular hair length is 44.7%, and the contribution degree of cellulose is 26.0%. It shows that the main influencing factors for the thermal quality combustion of moxa floss are the non-glandular hair length and cellulose;

[0109] That is to say, for Artemisia argyi Lévl. var. argyi, the standard value ranges of the lengths of non-glandular hairs at each leaf fluff ratio level are as follows:

[0110] (Leaf fluff ratio 3:1): 303.24 ± 14.99, (Leaf fluff ratio 5:1): 291.18 ± 14.99, (Leaf fluff ratio 10:1): 220.69 ± 7.21, (Leaf fluff ratio 15:1): 170.61 ± 7.10;

[0111] For Artemisia argyi Lévl. var. argyi, the standard value ranges of the cellulose contents at each leaf fluff ratio level are as follows:

[0112] (Leaf-fuzz ratio 3:1): 30.40 ± 4.07, (Leaf-fuzz ratio 5:1): 38.94 ± 5.64, (Leaf-fuzz ratio 10:1): 45.38 ± 5.56, (Leaf-fuzz ratio 15:1): 49.40 ± 0.93;

[0113] For Artemisia brachyphylla, the standard value ranges of the lengths of non-glandular hairs at each leaf-fuzz ratio level are as follows:

[0114] (Leaf-fuzz ratio 3:1): 461.92 ± 23.52, (Leaf-fuzz ratio 5:1): 293.82 ± 21.10, (Leaf-fuzz ratio 10:1): 249.38 ± 16.90, (Leaf-fuzz ratio 15:1): 197.22 ± 14.08;

[0115] For Artemisia brachyphylla, the standard value ranges of the cellulose contents at each leaf-fuzz ratio level are as follows:

[0116] (Leaf-fuzz ratio 3:1): 28.16 ± 2.98, (Leaf-fuzz ratio 5:1): 32.95 ± 4.44, (Leaf-fuzz ratio 10:1): 43.14 ± 8.68, (Leaf-fuzz ratio 15:1): 47.36 ± 9.49;

[0117] After obtaining the standard value ranges of the lengths of non-glandular hairs and the cellulose contents at each level of various moxa fuzzes, it is possible to determine the leaf-fuzz ratio of moxa fuzz with an unknown leaf-fuzz ratio:

[0118] Taking Qiai with an unknown leaf-fuzz ratio as an example:

[0119] Using the physical separation method, observe the length of non-glandular hairs under a microscope, and use professional image analysis software to calculate its length distribution range of 123.70 - 150.70 μm; according to the Van Soest method in the literature, determine the neutral detergent fiber, acid detergent fiber, acid-insoluble lignin, and ash of the Qiai fuzz with this unknown leaf-fuzz ratio, and use the difference weight method to calculate the cellulose content, which is 54.9%.
