Description

Quality detection method of lung-clearing and toxin-expelling soup established based on thin-layer identification method

Technical Field

The invention relates to a preparation process of lung-clearing and toxin-expelling soup and a method for detecting or monitoring the quality of a preparation, in particular to a quality control method for identifying traditional Chinese medicinal materials, controlling process parameters and analyzing the quality of a finished product for the preparation process and the preparation of the lung-clearing and toxin-expelling soup, and a method for producing the lung-clearing and toxin-expelling soup according to the quality control method.

Background

The lung-heat clearing and toxin expelling soup is prepared from traditional Chinese medicine classic formulas, and comprises Maxingshigan soup, blackberry lily ephedra soup, Xiaochaihu soup and Wuling powder, and has mild nature and taste. The main medicine components of the prescription are as follows: 9g of ephedra, 6g of honey-fried licorice root, 9g of almond, 15-30 g of gypsum (decocted first), 9g of cassia twig, 9g of rhizoma alismatis, 9g of polyporus umbellatus, 9g of bighead atractylodes rhizome, 15g of poria cocos, 16g of radix bupleuri, 6g of scutellaria baicalensis, 9g of ginger processed pinellia tuber, 9g of ginger, 9g of aster, 9g of flos farfarae, 9g of blackberry lily, 6g of asarum, 12g of Chinese yam, 6g of immature bitter orange, 6g of dried orange peel and 9g of wrinkled gianthyssop herb.

In order to effectively monitor the quality of the traditional Chinese medicine components, the identification and effective content determination of the components of the raw materials are required. The thin layer identification method is a common method in the establishment of a medicine quality standard, a proper stationary phase is coated on a glass plate, plastic or an aluminum sheet during identification so as to form a uniform thin layer, and the thin layer is developed and then compared with a chromatogram ratio shift value (Rf) obtained by a proper reference substance according to the same method so as to complete the identification and the content determination of the medicine.

The Chinese pharmacopoeia stipulates that when thin-layer identification is carried out, a test drug and a standard reference substance are respectively absorbed, respectively spotted on the same silica gel G thin-layer plate, developed on a corresponding identification developing agent, taken out, dried in the air and then sprayed with a color developing agent. Only when the same color spot appears in the test product chromatogram at the position corresponding to the control product chromatogram, the corresponding pharmaceutical active ingredient is identified as being contained in the test product.

For example, in the prepared Chinese medicinal granule, the identification of herba Ephedrae component is regulated by Chinese pharmacopoeia using chloroform-methanol-concentrated ammonia water (20: 5: 0.5) as developing agent. However, in the existing literature, Zhanghua (determination of ephedrine in the formula of sisal hemp by thin-layer scanning method, 2007) reports that chloroform-methanol-concentrated ammonia water (10: 2: 0.1) has a good development effect, the Rf value of ephedrine is 0.35, and the separation is good. Zhang Jun ('wind-cold common cold granule ephedra thin layer chromatography identification method research', 2011) reports that methanol, ethyl acetate and ammonia water (5: 15: 2) are used as developing agents.

The identification of immature bitter orange ingredient is regulated in Chinese pharmacopoeia, and n-butyl alcohol-glacial acetic acid-water (4: 1: 5) is used as a developing agent. However, in the existing literature, liu zhen hua (thin layer chromatography identification of immature bitter orange masses removing pill, 2010) reports that cyclohexane: acetone =10:3 as developing solvent.

The identification of the radix scutellariae component is regulated in Chinese pharmacopoeia, and toluene-ethyl acetate-methanol-formic acid (10: 3:1: 2) is used as a developing agent. However, in the existing literature, Jiangyu (thin-layer identification of scutellaria baicalensis in Huanglian Shangqing tablets and content determination of baicalin, 2018) reports that ethyl acetate-butanone-formic acid-water (10: 7: 1) is used as a developing agent.

The ginger ingredient is identified according to the regulations of Chinese pharmacopoeia, and petroleum ether (60-90 ℃) -trichloromethane-ethyl acetate (2: 1:1) is used as a developing agent. However, in the existing literature (thin-layer scanning method for simultaneously measuring 6-gingerol and 6-gingerol in ginger, in the division of botanical drug in foreign medicine, 2008), n-hexane-diethyl ether (4:6, v/v) can be used as a developing agent, and Li (thin-layer scanning method for measuring the content of 6-gingerol in ginger, 2004) can also be used as a developing agent.

The method for identifying the asarum component is specified in Chinese pharmacopoeia and adopts petroleum ether (II) -ethyl acetate (3: 1) as a developing agent. However, in the existing literature, it is reported that plum blossom (thin layer identification of pseudo-ginseng and erigeron breviscapus in tongshu tablets, 2006) can also use ethyl acetate-butanone-formic acid-water (5:3:1:1) as a developing agent. In the Chinese medicinal preparation, thin-layer chromatography identification of herba Erigerontis (2011) reports that toluene-ethyl acetate-formic acid (1: 7: 1) can also be used as developing solvent.

The identification of the blackberry lily components is regulated in Chinese pharmacopoeia, and trichloromethane-butanone-methanol (3: 1:1) is used as a developing agent. However, in the existing literature, onghao (thin-layer identification of iris tectorum, belamcanda chinensis and its confounders, 1996) also reports that benzene: ethyl acetate (8: 5) as a developing solvent; huangming Sheng (rhizoma Belamcandae, and rhizoma Belamcandae thin layer chromatography and content determination research, 1997) reported that chloroform-methanol-formic acid (10: 1: 0.1) can also be used as developing agent.

The cassia twig component is identified by stipulation of Chinese pharmacopoeia, petroleum ether (60-90 ℃) and ethyl acetate (17: 3) are used as developing agents. However, in the existing literature, the yuanhui (thin layer chromatography identification of cassia twig and poria cocos in wuling tablets, 2010) reports that cyclohexane-ethyl ether-glacial acetic acid (5: 5: 0.1) can be used as a developing agent.

The method for identifying the components of the common coltsfoot flower is specified in Chinese pharmacopoeia and takes petroleum ether (60-90 ℃) and acetone (6: 1) as developing agents. However, in the existing literature, it is reported that petroleum ether (60-90 ℃) and ethyl acetate (4: 1, v/v) can be selected as a new development system; and compared with petroleum ether-acetone (6: 1, v/v) development system provided by pharmacopoeia, wherein the former is single development, and the latter is equidirectional secondary development.

The identification of the dried orange peel component is carried out by taking ethyl acetate-methanol-water (100: 17: 13) as a developing agent, spreading to 3cm, taking out, drying, taking an upper layer solution of toluene-ethyl acetate-formic acid-water (20: 10:1: 1) as a developing agent, spreading for the second time to 8cm.

The identification of the aster components is regulated in Chinese pharmacopoeia, and petroleum ether (60-90 ℃) and ethyl acetate (9: 1) are used as developing agents. However, in the existing literature, buthan (morphological and thin layer chromatography identification research of 3 sources of aster tataricus medicinal materials, 2015) reports that 95% ethanol-formic acid-water (2: 0.15: 1) is used as a developing agent. Wangshouzhong (thin-layer chromatography identification of ephedra, liquorice, aster and radix ophiopogonis in a mixture for clearing heat and relieving sore throat, 2006) reports that petroleum ether (60-90 e) -ethyl acetate (9: 1) is used as a developing agent.

The method for identifying Alismatis rhizoma component adopts cyclohexane-ethyl acetate (1: 1) as developing agent. However, in the existing literature, Wangxuiqin (a thin-layer identification method research on the traditional Chinese patent medicine Alisma orientale in the pill of rehmannia, 2018) reports that trichloromethane-ethyl acetate-formic acid (12: 7: 1) or cyclohexane-ethyl acetate (1: 1) is used as a developing agent. Scleimna (Alisma orientale thin layer chromatography identification research, 2006) reports cyclohexane-ethyl acetate-acetone (4:2:1) as a developing agent.

The identification of the liquorice component is regulated in Chinese pharmacopoeia, and ethyl acetate-formic acid-glacial acetic acid-water (15: 1: 1: 2) is used as a developing agent. However, in the existing documents, ethyl acetate-formic acid-glacial acetic acid-water (15: 1: 1: 2) is reported as a developing solvent in plum sensitivity (2015) and plum-Yuping (2015) which are thin layer identification method for liquorice in all seasons cold tablets).

The identification of bupleurum components is regulated in Chinese pharmacopoeia by taking ethyl acetate-ethanol-water (8: 2:1) as a developing agent. However, in the existing literature, the qualitative identification of bupleurum and liquorice in bupleurum tenue granules by thin layer chromatography reports that chloroform-methanol-water (80:25:2) is used as a developing agent. Liyunjing (thin-layer chromatography identification of bupleurum in the capsule for resolving depression and soothing nerves, 2017) reports that the ratio of ethyl acetate to ethanol to water is (9: 2:1) as a developing agent.

The identification of the components of the bighead atractylodes rhizome is regulated in Chinese pharmacopoeia, and petroleum ether (60-90 ℃) and ethyl acetate (50: 1) are used as developing agents. However, in the existing literature, europahodene (an improvement of a thin-layer identification method of bighead atractylodes rhizome, 2019) reports that cyclohexane: isopropanol (20: 1, v/v), european pharmacopoeia for ethyl acetate: heptane (5: 95, v/v) was used as developing solvent.

The identification of bitter almond components specified in Chinese pharmacopoeia uses chloroform-ethyl acetate-methanol-water (15: 40: 22: 10) as a developing agent, and a lower layer solution is placed at 5-10 ℃ for 12 hours. However, in the literature, it is reported that liquiritigenin (thin-layer scanning assay of amygdalin in bitter apricot kernels and peach kernels, 1992) is prepared by dissolving in water-saturated chloroform: methanol (2: 1) is used as a developing agent. The study of measuring the content of amygdalin in the ephedra decoction granules by a thin-layer scanning method reports that n-butyl alcohol: acetic acid: water (95: 5: 25) is the developing solvent.

It can be seen that, in addition to the gypsum components that do not require thin layer analysis, most of the components are identified one by one because the developing agent used in the thin layer identification method is different in either composition or content.

However, the lung clearing and toxin expelling soup is prepared by combining and adjusting 4 ancient prescriptions, wherein the medicinal taste is more than 20. If the different medicinal components in the finished granules are identified one by one, thin-layer identification tests are carried out for almost 20 times, which obviously does not facilitate the requirements of quickly producing the anti-epidemic medicines and simultaneously monitoring the product quality.

In addition, as the lung-clearing and toxin-expelling soup belongs to a newly found and determined prescription and has no uniform production standard temporarily, the production processes are different from each other due to the fact that various manufacturers produce the soup according to actual conditions, which may bring certain adverse effects on the standardized production of the traditional Chinese medicine preparation.

Therefore, a method for quickly and simply monitoring the quality of the lung-clearing and toxin-expelling soup product and a standardized production method based on the quality monitoring method are needed.

Decocting the raw materials twice with water for 1 hour each time, filtering, mixing decoctions, concentrating the filtrate under reduced pressure to obtain fluid extract with relative density of 1.03-1.05 (70 ℃), adding an appropriate amount of maltodextrin, and drying or pulverizing to obtain 1000g of granules.

Further, 10 times of water is added for the first time, and the mixture is soaked for 0.5 hour and decocted for 1.0 hour; adding 10 times of water for the second time, decocting for 1.0 hr, mixing decoctions, and filtering;

further, concentrating the filtrate at 75 +/-5 ℃ under reduced pressure to obtain clear paste with the density of 1.03-1.05 (70 ℃), and centrifuging at 10000 rpm/min;

further, taking the centrifuged clear paste, adding a proper amount of maltodextrin (the total amount of each prescription is 40g, and the solid content of the centrifuged clear paste is about 10.5 percent of the prescription), dissolving, uniformly mixing, and spray drying to obtain extract powder;

further, taking extract powder, adding a proper amount of adhesive (water), boiling and granulating, and granulating to obtain 1000g of granules;

further, the granules are subpackaged into 10 g/bag and packaged by a composite film.

Further, the quality monitoring comprises detecting and evaluating the quality of the product, judging whether the product quality is qualified or not, thereby determining whether to continue or interrupt the production process of the product, and guiding the product to carry out standardized production.

The first principle of the invention lies in that on the basis of thin-layer identification developing agents of various traditional Chinese medicine components published in Chinese pharmacopoeia, a great exploration attempt is carried out, the quality monitoring of partial components which do not need or have small influence on the product quality is omitted, and various developing agents of main ephedra, bitter apricot seed, honey-fried licorice root, cassia twig, rhizoma alismatis, rhizoma atractylodis macrocephalae, radix bupleuri, radix scutellariae, ginger, radix asteris, coltsfoot flower, blackberry lily, asarum, immature bitter orange, dried orange peel, wrinkled gianthyssop herb and other components are combined and tested, so that a plurality of traditional Chinese medicine components can be simultaneously detected by a few identification developing agent groups, and the process of optimizing and simply monitoring the quality is carried out on the basis of ensuring the identification effect.

The second principle of the invention is that under the condition of determining and identifying the developing agent group, the technological parameters such as reagent extraction parameters and the like are further adjusted and optimized, and the stability and the repeatability of the optimized developing agent are verified under different quality control environments (such as high temperature, low temperature, high humidity and low humidity and the like).

The third principle of the invention is that the result of the quality monitoring determined above is introduced into the production of the lung-clearing and toxin-expelling soup, thereby providing a standardized production method which can meet the product quality.

Compared with the prior art, the invention has the following advantages:

the invention refers to the standards of main medicinal materials in a prescription recorded in Chinese pharmacopoeia, the relevant standards of relevant Chinese medicinal preparations and literature data, carries out a great exploration attempt, omits the quality monitoring of partial components which do not need or have little influence on the product quality, selects a standard method different from the recommended Chinese pharmacopoeia, carries out combination test on various developing agents of main ephedra, bitter apricot seed, honey-fried licorice root, cassia twig, rhizoma alismatis, rhizoma atractylodis macrocephalae, radix bupleuri, radix scutellariae, ginger, aster, coltsfoot flower, blackberry lily, asarum, immature bitter orange, dried orange peel, wrinkled gianthyssop herb and other components, realizes that a few identifying developing agent groups can simultaneously detect a plurality of Chinese medicinal components, and optimizes and simply monitors the quality on the basis of ensuring the identifying effect.

At present, no report about the quality of TLC detection of the complex synthesis is available, so the invention is the first invention research on systematic TLC detection quality in China.

Although the TLC method is a mature method for detecting the quality of the traditional Chinese medicine, the detection means is conventional, but in the face of a quality control method which has so many medicines to be detected and needs major research and breakthrough in a short time, the method still pays a large amount of time and substances, and creatively performs grouped thin-layer chromatography test, so the method has high technical prospect.

The invention proves that the standard method of Chinese pharmacopoeia is not suitable for thin layer analysis for detecting the multi-component composition through a large amount of test data, so that the thin layer analysis needs to be searched and verified one by one. Therefore, the inventors conducted a large number of experimental screens using the following research approaches:

the existing developing agent is still used for individual medicinal flavors, but the medicinal flavor (such as radix scutellariae) is creatively combined with other medicinal flavors, and the technical effect that the same developing agent can be used for simultaneously distinguishing a plurality of medicinal flavors is obtained through screening through a research mode;

for the components of asarum, blackberry lily, cassia twig, coltsfoot flower, dried orange peel and aster, the invention unexpectedly discovers that a secondary developing solvent system can be selected to clearly detect the components through a large number of experiments. Tests show that the secondary developing solvent system can analyze and detect 6 components at one time, and the components do not interfere with each other, so that the detection time and cost are effectively saved;

for some components which have similar components and are difficult to analyze in the same developing solvent, the invention respectively applies different developing solvents to perform chromatographic identification (such as dried orange peel and immature bitter orange) through experiments or under the condition of not adding extra developing solvent combinations, or the components are proved to have high similarity of isomers through the experiments, so that the identification can be completed only by selecting one with the best separation effect (such as aster and bighead atractylodes rhizome);

for the developing solvent and the chromatography method which are recommended by Chinese pharmacopoeia, such as rhizoma alismatis, and the like, through tests, the invention finds that different developing solvents are selected and matched with improved test samples, and a better detection effect can be obtained.

Through the creative screening thought and a large number of comparison tests, the invention can omit unnecessary chromatographic separation components and can realize accurate quantitative and qualitative analysis of all components. The developing agent system has good repeatability, high stability in high-temperature and low-temperature environments, high detection quality, saved detection cost and time, and can obtain stable quality detection effect.

In addition, in the quality detection method, a large number of specific detection data point values are involved, so that although the protection range is narrower, unqualified products with poor or insufficient effects are eliminated through various specific detection data point values, and the quality detection method is very suitable for establishing a stable quality control standard and meets the requirements of traditional Chinese medicine production.

The invention abandons the detection of gypsum and the components of largehead atractylodes rhizome, wrinkled gianthyssop herb, almond and the like, and provides only 5 developing agent groups, namely, the quality monitoring and evaluation can be carried out on 13 components, and a quality standard monitoring method which is enough to evaluate 20 components of the lung-clearing and toxin-expelling soup is established, thereby effectively improving the production process.

Example 3 analysis of different thin layer identification spreaders

Referring to the identification items of liquorice, scutellaria, dried ginger, immature bitter orange, bitter apricot seed, blackberry lily, asarum, dried orange peel, cablin potchouli herb, bupleurum capsule and the like in the first edition of Chinese pharmacopoeia 2015, the following existing developing agents are researched in a mode:

(1) "Licorice" identification developing agent: ethyl acetate-formic acid-glacial acetic acid-water (15: 1: 1: 2);

(9) the identification developing agent of the bupleurum tenue capsule comprises the following components: chloroform-methanol-water (13: 6: 1).

Packet embodiments

Example 3.1 identifying developing agent with "licorice", selecting each test sample and sample, developing with ethyl acetate-formic acid-glacial acetic acid-water (15: 1: 1: 2), the development result on Merck precast slab is shown in figure 1, wherein A is under undeveloped 365 nm; b is 10% sulfuric acid ethanol for visualization under 365 nm; c is 10% sulfuric acid ethanol color development under natural light, T: 25 ℃, RH: 60 percent.

Each strip shows schematically:

1. cassia twig 2, dried orange peel 3, asarum herb 4, blackberry lily 5, licorice root 6, white atractylodes rhizome 7, baikal skullcap root 8, bitter apricot seed 9, alisma rhizome 10, aster

11. Flos farfarae 12, herba agastaches 13, fructus aurantii immaturus 14, herba ephedrae 15, ginger 16, radix bupleuri 17, test solution 418 and test solution 5;

the analysis shows that:

firstly, bright blue fluorescent spots of the bighead atractylodes rhizome, the aster and the immature bitter orange before developing under 365nm ultraviolet interfere with each other, and the immature bitter orange and the ephedra have one blue fluorescent spot respectively without interference.

Secondly, under the condition of natural light color development of ethanol sulfate, each component has a serious trailing interference band, bright blue fluorescent spots of liquorice, bighead atractylodes rhizome, aster and immature bitter orange after color development under 365nm ultraviolet interfere with each other, 1 blue fluorescent spot of the immature bitter orange does not interfere with the immature bitter orange, and 2 yellow fluorescent spots of the liquorice do not interfere with the immature bitter orange.

In summary, the conventional licorice identification developer is not suitable as a developer for combined detection because it cannot be used for TLC analysis of not only licorice components but also other drugs.

Example 3.2 using a ginger identification developing agent, petroleum ether (60-90 ℃) -chloroform-ethyl acetate (2: 1:1) for development,

as shown in FIG. 1, A is an undeveloped 254nm inspection; b is an undeveloped view at 365 nm; c is 5% vanillin sulfuric acid color development.

Strip shows that:

1. cassia twig 2, dried orange peel 3, asarum herb 4, belamcanda rhizome 5, licorice root 6, bighead atractylodes rhizome 7, scutellaria root 8, bitter apricot seed 9, alisma rhizome 10, aster 11, coltsfoot flower 12, wrinkled gianthyssop 13, immature bitter orange 14, ephedra herb 15, ginger 16, bupleurum root 17, test solution 418, test solution 5

Analysis shows that:

firstly, the blackberry lily has a spot under 254nm without interference, the test solution 1 should be selected as the test solution, and other medicinal materials cannot be identified.

② ginger does not show any result under 254nm and 365nm, and the color development is clearer only in vanillin.

③ the radix scutellariae shows more obvious single bands under 254nm and 365nm, and can clearly separate a plurality of interference bands without tailing under the condition of vanillin development.

In conclusion, although the developing agent can identify ginger under the condition of vanillin development, it does not show any result at 254nm and 365nm, which shows no indication effect on the final vanillin. Meanwhile, other herbs are either heavy or not prominent in a single band.

However, unexpectedly, the developing agent can identify ginger and scutellaria simultaneously under the condition of vanillin development, and it is predicted that the same developing agent can be used for the two components. As shown in fig. 2.

Example 3.3 identification of developing agent with "Scutellaria baicalensis Georgi", development with toluene-Ethyl acetate-methanol-formic acid (10: 3:1: 2)

According to the results of example (2) and fig. 2, scutellaria baicalensis and ginger were tested using a scutellaria baicalensis identification developer, while citrus peel, almond and wrinkled gianthyssop ingredients were tested. The development results of the Merck precast slab are shown in FIG. 3, where A is observed at 254nm without developing color; b is an inspection under the condition of no color development of 365 nm; c is 5% vanillin sulfuric acid color development sunlight inspection, T: 25 ℃, RH: 60 percent.

Strip schematic:

1. scutellariae radix control 2, rhizoma Zingiberis recens control 3, pericarpium Citri Tangerinae control 4, and test solution 1

5. Sample solution 26, bitter apricot seed drug contrast 7, wrinkled gianthyssop drug contrast

Analysis shows that:

the scutellaria baicalensis and the ginger can be identified and can be basically separated, wherein the ginger shows a clear single strip in the 5 percent vanillin sulfuric acid color development sunlight.

Secondly, the background interference of the test sample is large, and the treatment of the test sample needs to be further optimized.

Thirdly, the dried orange peel, the bitter apricot kernel and the wrinkled giant hyssop have a large number of trailing interference bands, and the unfolding system cannot be adopted.

Therefore, considering that the developing agents of the examples (2) to (3) have better developing effects on the ginger and the radix scutellariae, and are more consistent with the inventive concept of reducing the combination of the developing agents, the developing agent of the ginger is determined not to use the developing agent recommended by pharmacopoeia, but to use the developing agent of the radix scutellariae.

Example 3.4 identification of developing agents with "immature bitter orange": n-butanol-glacial acetic acid-water (4: 1: 5) development

The chromatographic results of the 16 flavors and the two test solutions are shown in FIG. 4-1, wherein A is observed under the condition of non-color development at 254 nm; b is an undeveloped visual field at 365nm, T: 25 ℃, RH: 60 percent.

Each strip shows schematically:

Analysis shows that:

under 254nm, fructus Aurantii Immaturus and Scutellariae radix are clear, and have few interference bands, but other medicinal components are fuzzy and difficult to separate

② 365nm, the observation shows that the Chinese ephedra has very clear bands and no interference band, but the immature bitter orange has more interference bands and the radix scutellariae has serious tailing, which indicates that the developing agent is not suitable.

Therefore, the immature bitter orange needs to be subjected to ninhydrin ethanol color development and recheck, and meanwhile, the recheck effect of the ephedra herb component is analyzed.

The results are shown in FIG. 4-2.

Each strip shows schematically:

1. immature bitter orange 1 (extracting with ammonia water and n-butanol) 2. immature bitter orange 2 (extracting with ammonia water and ethyl acetate)

3. Herba Ephedrae 1 (extracted with n-butanol and ammonia) 4. herba Ephedrae 2 (extracted with ethyl acetate and ammonia)

5. Test article (chloroform extraction with ammonia) 6. test article (ethyl acetate extraction with ammonia)

7. Sample 28 sample (adding aqueous ammonia n-butanol extraction)

Wherein A is the detection under the condition of developing no color at 254 nm; b is 0.5% ninhydrin ethanol coloration natural light, T: 25 ℃, RH: 60 percent.

Analysis shows that:

ninhydrin ethanol color development, compared with the extraction with ammonia water and ethyl acetate, the chromatographic results of the immature bitter orange and the ephedra herb extracted by the ammonia water and the n-butyl alcohol are clearer, and the results are all superior to the comparison results of the test samples extracted by the ammonia water and ethyl acetate or the ammonia water and the n-butyl alcohol

② the ninhydrin ethanol color development result of the ephedra is unexpectedly superior to the ninhydrin ethanol color development result of the immature bitter orange.

Therefore, immature bitter orange developing agent can be selected, meanwhile, the ephedra is developed and analyzed, and ninhydrin ethanol color development is recommended to be used as a final chromatographic analysis means.

Example 3.5 "belamcanda" identification development agent: trichloromethane-butanone-methanol (3: 1:1)

The results are shown in FIG. 5, where A is observed at 254nm without coloration; b is an undeveloped visual field at 365nm, T: 25 ℃, RH: 60 percent.

Each strip shows schematically:

1. cassia twig 2, dried orange peel 3, asarum herb 4, belamcanda rhizome 5, licorice root 6, white atractylodes rhizome 7, baikal skullcap root 8, bitter apricot seed 9, alisma orientale

10. Aster 11, coltsfoot flower 12, wrinkled gianthyssop 13, immature bitter orange 14, ephedra 15, ginger 16 and bupleurum

17. Test solution 118 test solution 2

Analysis shows that:

firstly, at 254nm, only blackberry lily and immature bitter orange can be detected, and other components are seriously interfered or cannot be displayed.

② at 365nm, only Atractylodes macrocephala and Aster tataricus can be detected, but the evidence of the existence of them at 254nm is lacked.

In summary, the tectonic agent of the blackberry lily does not meet the inventive concept of reducing the combination of the tectonic agent, so the tectonic agent of the blackberry lily is determined not to use the development agent recommended by the pharmacopoeia.

Example 3.6 "asarum" identification development reagent: petroleum ether (II) -acetic acid ethyl ester (3: 1)

The results are shown in FIG. 6, where A is observed at 254nm without coloration; b is inspection under 365 nm; c is vanillin development, T: 25 ℃, RH: 60 percent.

Each strip shows:

1. test solution 12, cassia twig 3, dried orange peel 4, asarum 5, blackberry lily 6, bighead atractylodes rhizome 7, test solution 1

8. Alisma orientale 9, aster 10, coltsfoot flower 11, wrinkled gianthyssop 12, immature bitter orange 13 and test solution 1

Analysis shows that:

at 254nm, only asarum can be detected, and other components are seriously interfered or gather together and are not separated forward to form independent bands.

② at 365nm, the asarum, cassia twig, test solution 1 and aster appear separate independent bands, but other components are seriously interfered or gather together and do not separate forward to form independent bands.

③ under the condition of vanillin display, the isolated bands of asarum are not clear, but the other components have almost no visible isolated bands.

In conclusion, the spreading agent of asarum is not in line with the inventive concept of reducing the combination of spreading agents, and thus it was determined that the spreading agent of asarum does not use the spreading agent recommended by pharmacopoeia.

Example 3.7 for the remaining ingredients of undetermined developing solvent, "orange peel" was chosen to identify the developing solvent: spreading to 3cm with ethyl acetate-methanol-water (100: 17: 13) as developing agent, taking out, air drying, spreading to 8cm with upper solution of toluene-ethyl acetate-formic acid-water (20: 10:1: 1) as developing agent.

The results are shown in FIG. 7-1, where A is observed at 254nm without coloration; b is a visual inspection at 365nm, T: 25 ℃, RH: 60 percent.

Analysis shows that:

the asarum, the blackberrylily rhizome and the common coltsfoot flower under 254nm are clearly displayed, and basically have no interference.

② the asarum, the coltsfoot flower and the cassia twig under 365nm are clearly displayed, basically have no interference and can be used as an identification method.

In conclusion, the first development with ethyl acetate-methanol-water (10: 17: 13) can distinguish asarum, blackberry lily, coltsfoot flower and cassia twig, which preliminarily predicts to find a chromatography mode in accordance with the reduction of the combination of the developing agent.

Therefore, the second expansion is considered. The results are shown in FIG. 7-2, where A is observed at 254nm without coloration; b is an undeveloped view at 365 nm; c is the visual observation of aluminium trichloride test solution under the condition of 365nm of color development, T: 25 ℃, RH: 60 percent.

Strip schematic:

Analysis shows that:

7-2A and 7-2B as a comparison test under the condition of a secondary developing solvent, the results are the same as those of 7-1A and 7-1B, and the developing effects of the secondary developing solvent at 254nm and 365nm are the same as those of the primary developing solvent.

In FIG. 7-2C, although the Aster tataricus band has a certain tailing under the condition of 365nm of color development of the aluminum trichloride test solution, the main band is very prominent and separated and has no tailing, so that the secondary developing agent is very suitable for the secondary developing agent.

Thirdly, in the figure 7-2C, the cassia twig, the dried orange peel, the asarum and the blackberry lily have no trailing interference band and have good separation effect. Although the coltsfoot flower has a certain tail, the main belt is very protruding and separated and has no tail, so the coltsfoot flower is very suitable for the secondary developing agent.

In FIGS. 7-2C, although the white atractylodes rhizome has clear separation bands, it is likely to interfere with the results of Aster tataricus, and it is necessary to analyze the thin layer chromatography behavior of the interfering components of the white atractylodes rhizome and the Aster tataricus.

In fig. 7-2B and 7-2C, the orange peel and the immature bitter orange have similar results because of the same components such as hesperidin, and the same developing agent is not easy to use. However, in the developing agent, compared with immature bitter orange, the tangerine peel has clear separated bands and no tailing interference bands, so that the developing agent can be selected for analyzing the tangerine peel.

Example 3.8 chromatographic behavior study of Aster tataricus and Atractylodes macrocephala interfering components

According to the results of example (7), the chromatographic behavior of interfering components of Aster tataricus and Atractylodes macrocephala was analyzed, and an appropriate developing agent and a component to be tested were determined.

The results are shown in FIG. 8, where 8-A is petroleum ether (II) -ethyl acetate (3: 1); 8-B is ethyl acetate-methanol-water (100: 17: 13); 8-C is toluene-ethyl acetate-formic acid-water (20: 10:1: 1) (secondary development); 8-D is trichloromethane-butanone-methanol (3: 1: 1).

Analysis shows that: selecting 4 kinds of thin layer development conditions, wherein the main spots of the aster and the white atractylodes rhizome are coincided in three ranges of Rf0.1-0.3, Rf0.4-0.6 and Rf0.7-0.9, but the fluorescence intensities of the aster and the white atractylodes rhizome are different, considering that the aster and the white atractylodes rhizome may be isomers,

therefore, both Aster and Atractylodes cannot be detected simultaneously by the same system of developing agent.

Combining the results of example (7) and fig. 7, it was confirmed that the selected aster was suitable for the secondary spreading agent system because the band of aster was more prominent and separable than that of atractylodes macrocephala.

In conclusion, it was determined that asarum herb, blackberry lily, cassia twig, tussilago farfara, dried orange peel and aster root were developed for the first time by using ethyl acetate-methanol-water (100: 17: 13) as a developing solvent, and then developed for the second time by using an upper solution of toluene-ethyl acetate-formic acid-water (20: 10:1: 1) as a developing solvent.

Example 3.9 identification of "patchouli" developing agents: petroleum ether (I) -Ethyl acetate-glacial acetic acid (95: 5: 0.2)

The results are shown in FIG. 9, where A is observed at 365nm without coloration; b is the observation under the developing sunlight of ferric trichloride, T: 25 ℃, RH: 60 percent.

Strip schematic:

8. Alisma orientale 9, aster 10, coltsfoot flower 11, patchouli 12, immature bitter orange 13 and test solution 1

Analysis shows that:

under 365nm, only cassia twig and test solution 1 present clear separation bands, and other components are agglomerated together and cannot be separated, so that only cassia twig can be detected, and other medicinal material components cannot be detected;

② after ferric trichloride color development, herba Agastaches drug control and sample components are agglomerated together and can not be separated, therefore, any spot showing separation can not be detected.

In conclusion, the production process of the product is water decoction, and volatile oil is not additionally extracted, so that agastache rugosus cannot be detected and cannot be identified. At the same time, the developer system cannot be used for chromatographic analysis of other components.

Example 3.10 identification of bupleurum tenue capsules developing agent: chloroform-methanol-water (13: 6: 1)

The results are shown in FIG. 10, where A is observed at 254nm without coloration; b is an undeveloped view at 365 nm; c is inspection of dimethylaminobenzaldehyde sulfuric acid ethanol color development at 365 nm; d is the content of T: 25 ℃, RH: 60 percent.

Strip schematic: 1. bupleurum root 2, test solution 53, licorice root 4, test solution 35, blackberry lily 6, test solution 1

Analysis shows that:

firstly, the bupleurum and the liquorice present clear separation bands under four display conditions, and main bands do not interfere with each other;

② the blackberry lily can be clearly separated under the condition of the color development display of the dimethylaminobenzaldehyde sulfuric acid ethanol, but the color development effect is not as good as that of the bupleurum and the liquorice.

And (4) conclusion: the developing agent can separate bupleuri radix, Glycyrrhrizae radix, and rhizoma Belamcandae. However, as the separable components of the bupleurum, the liquorice and the blackberry lily are more, in order to avoid the interference of the components of the blackberry lily with the detection result and also to consider that the blackberry lily can be already included in the detection group of the secondary developing solvent, the developing solvent is recommended to be used for detecting the bupleurum and the liquorice.

Example 3.11 using a developing agent different from alisma identified in chinese pharmacopoeia: chloroform-ethyl acetate-formic acid (6: 3.5: 0.5)

"Chinese pharmacopoeia" 2015 edition for Alismatis rhizoma thin layer analysis: the results are shown in FIG. 11, in which A is observed at 254nm without coloration, using cyclohexane-ethyl acetate (1: 1) as developing agent; b is an undeveloped view at 365 nm; c is detected under the condition that 10% sulfuric acid ethanol develops color at 365nm, T: 25 ℃, RH: 60 percent.

Analysis shows that:

firstly, under the display conditions of 254nm and 365nm, the blackberrylily rhizome, the radix scutellariae and the flos farfarae can display separated spots, but the zerumbet cannot display the separated spots, and only the contrast display a plurality of spots;

secondly, under the condition of developing color by 10% sulfuric acid ethanol at 365nm, a plurality of separated spots appear on the rhizoma alismatis medicinal material, although a plurality of spots also appear in the contrast, the trailing interference band is serious, and the test solution 1 needs to be exchanged for further verification.

And (4) conclusion: the developing agent can be used for separating rhizoma Belamcandae, Scutellariae radix, and flos Farfarae. However, due to the fact that the belamcanda chinensis, radix scutellariae and flos farfarae have more separable components, in order to avoid the components from interfering with the detection result, the components can be taken into the detection group with the determined developing agent, and therefore the developing agent is recommended to be used for further verifying the rhizoma alismatis.

The control medicinal materials and the negative control are prepared by the same method, and the result shows that the identification can be realized.

In conclusion, for Alisma orientale, it is recommended to use an improved developing agent, and an improved test solution Ym is required to obtain a good detection effect.

Compared with the liquorice positive control, the sample also presents 2 strips with the same size at the same position in the middle part, which indicates that the sample contains the expected medicinal material components; compared with the positive control of radix bupleuri, the test sample also presents a plurality of strips with the same size at the same position in the middle part, which indicates that the test sample contains the expected medicinal material components;

comparing with licorice negative control, the sample has no strip with same position, which shows that the two components are different greatly; in comparison with the Bupleurum negative control, 1 band with the same brightness and size appears on each test sample at the same position above and below, indicating that the test sample contains some components identical to those of the negative control.

And (4) conclusion: the combined developing agent can detect the components of the medicinal materials of the liquorice and the radix bupleuri, has fewer components as the same as those of negative control, and is beneficial to the identification of the liquorice and the radix bupleuri.

Table 7: 2 index component comparison with impurity removal

The results show that the baicalin content in the liquid medicine is not obviously different in the 2 impurity removal modes by adopting a centrifugal mode and a 300-mesh screen filtration mode, but the sample obtained by the filtration method is turbid in appearance, precipitates are generated in the process of placement, and the centrifugal sample does not have the problems of turbidity and precipitation, so that the centrifugal impurity removal mode is superior to the 300-mesh screen filtration mode, and centrifugation is selected as the impurity removal mode.

Example 8.4 screening study of drying regimes

And (4) simulating two drying modes of spray drying and reduced pressure drying to select a proper drying mode.

Table 8: results of different drying modes

From the above results, it can be seen that the baicalin content in the sample in the spray drying mode is slightly higher than that in the sample in the reduced pressure mode because the spray drying is instantaneous high temperature drying, the sample is heated for a short time, and the component is less affected by heat, so the spray drying is selected as the drying mode.

Example 8.5 adjuvant screening study

The common auxiliary materials for the traditional Chinese medicine granules comprise soluble starch, maltodextrin, lactose and the like, the type of the auxiliary materials can influence the formability, the stability and the total preparation amount of finished products, and the type of the auxiliary materials is necessary to be considered. 10g of granules are prepared according to 50g of crude drugs, and the influence of the auxiliary materials on the granulation process is examined under the condition of adopting a boiling granulation mode.

Table 9: influence of auxiliary materials on the granulation Process

Test No	Kind of auxiliary Material	Influence of the granulation Process	Yield (%)
				1	Soluble starch	Easy granulation and no caking	90.1
2	Maltodextrin	Easy granulation and no caking	89.6
				3	Lactose	Easy granulation and no caking	89.2

The results show that the three auxiliary materials can prepare the product meeting the requirements, and the yield of the finished product has no obvious difference. Because the dissolubility of the soluble starch is slightly poor, the clarity of the finished product solution is poorer than that of the rest two solutions; lactose is easy to absorb moisture and has higher cost price, so maltodextrin is selected as an auxiliary material.
