Description
Technical Field
The invention belongs to the technical field of medicines, and relates to a traditional Chinese medicine composition for oropharyngeal inflammatory diseases, which is a traditional Chinese medicine preparation of Kaihoujian spray of Miao medicine and has the effects of clearing away heat and toxic materials, and relieving swelling and pain; can be clinically used for treating acute and chronic pharyngolaryngitis, tonsillitis, sore throat, stomatitis and gingival swelling and pain; for example, it can be used for treating swelling and pain of throat, dry mouth, bitter taste of mouth, swelling and pain of gum, oral ulcer, and recurrent aphtha caused by lung and stomach heat accumulation. The traditional Chinese medicine composition can be particularly used for treating infantile oropharyngeal inflammatory diseases.
Background
The infant is tender and delicate in viscera, is the body of 'young yin and young yang', is not full in shape and qi, is normally loose in striae, is easy to be infected by exogenous pathogenic factors, and is easy to grab articles beside the body into the mouth due to curiosity and exuberance of the children on external things. With the influence of external factors such as climate change, environmental pollution and the like, families are not paying attention to the environment, children are easy to enter the environment from the mouth, and the secret of infant care (Dayun) is recorded in the book: the infants have delicate viscera, frequent insufficiency of the spleen and dysfunction of transportation and transformation, and are very easy to get ill. Epidemic toxin is in the mouth, nose and lung, stagnates in lung and spleen, and is caused by hands and feet, smokes the mouth and throat, and penetrates the skin externally, and causes herpes. "paediatrics clinical oral ulcer belongs to the disease that the common incidence is higher, it means that oral mucosa surface takes place superficial ulcer, and the pathogenesis is mainly coxsackie virus, bacterial infection, hand-foot-and-mouth disease and recurrent aphtha etc. and the infant often shows symptoms such as salivation, fever and crying [ Zhang Bo, etc.. montmorillonite powder is united kaihoujian and is compared with Bingpeng san and is treated the curative effect analysis of infant oral ulcer [ J ].

Test example 2: method for simultaneously and quantitatively measuring multi-index medicinal components of Kaihoujian spray
When various test solutions were measured in test example 1 above, it was found that after the test solutions were injected into the liquid chromatograph, the column pressure at the initial test was usually between 80 and 90bar, but after the test solutions were injected several times, the column pressure gradually increased, for example, after 5 test solutions were injected, the column pressure increased to between 120 and 130bar, while after 10 test solutions were injected, the column pressure increased to between 150 and 160bar, and after 15 test solutions were injected, the column pressure increased to between 210 and 220bar, and further increase of the column pressure was unacceptable; the column pressure can be returned to the initial state after 2 hours by backflushing the column with a mobile phase a/mobile phase B at a ratio of 10/90, but this operation is not desirable in large sample size analysis tests; it has been found that this increase in column pressure does not occur when testing the control solution, indicating that this increase in column pressure is due to the relevant components in the test solution. The inventor tries to use other brands of C18 columns (the column length, the column inner diameter and the packing granularity are the same), namely a Supelcoc C18 column, an Agilent C18 column and a Waters C18 column, tests are carried out according to test example 1, and the results also show that the column pressure is unacceptably increased along with the tests, for example, the column pressure of the three columns is increased to 202-210 bar, 185-192 bar and 205-212 bar respectively after 12 test sample solutions are injected into the three columns for testing. The inventor tries to simultaneously add 1.2% isopropanol and 0.2% ammonium chloride in mobile phase A, namely acetonitrile, and mobile phase B, namely 0.1% formic acid solution, so that both A and B contain two additives with the same concentration, and the elution is carried out according to the gradient elution procedure of experimental example 1, and other operation conditions are kept unchanged, and the results show that the initial column pressure is between 80 and 90bar when the test sample solution and other solutions are tested, the column pressure is still kept in the column pressure state after various solutions are tested for more than 30 times, for example, the column pressure is still between 85 and 95bar when the test sample solution is injected for 30 times, and the column pressure is still between 92 and 97bar when the test sample solution is injected for 50 times. Further, the inventors tried to add 1.2% isopropanol to both mobile phase a, i.e. acetonitrile, and mobile phase B, i.e. 0.1% formic acid solution, so that both a and B contain the same concentration of the additive, and still perform elution according to the gradient elution procedure of test example 1, and the other operation conditions are kept unchanged, and the results show that, when testing the sample solution and other solutions, the initial column pressure is between 80 and 90bar, the column pressure is still gradually increased when testing the sample solution, for example, the column pressure is increased to between 109 and 115bar after injecting 5 sample solutions, the column pressure is increased to between 133 and 140bar after injecting 10 sample solutions, and the column pressure is increased to between 160 and 168bar after injecting 15 sample solutions. Further, the inventor tries to add 0.2% ammonium chloride to both mobile phase a, i.e. acetonitrile, and mobile phase B, i.e. 0.1% formic acid solution, so that both a and B contain the same concentration of the additive, and still perform elution according to the gradient elution procedure of experimental example 1, and the other operation conditions are kept unchanged, and the results show that, when testing the sample solution and other solutions, the initial column pressure is between 80 and 90bar, the column pressure is still gradually increased when testing the sample solution, for example, the column pressure is increased to between 115 and 122bar after injecting 5 sample solutions, the column pressure is increased to between 140 and 150bar after injecting 10 sample solutions, and the column pressure is increased to between 180 and 190bar after injecting 15 sample solutions. From this, it is known that the simultaneous addition of both isopropyl alcohol and ammonium chloride to the mobile phase can avoid the problem of an increase in column pressure when testing the sample solution.
For this reason, in this test example 2, the same operation conditions as in test example 1 were used except that 1.2% isopropyl alcohol and 0.2% ammonium chloride were added to both of the mobile phase a, i.e., acetonitrile, and the mobile phase B, i.e., 0.1% formic acid solution, and various test solutions were prepared using test example 1, and the results of the various tests were substantially the same as in test example 1, and typical results were as follows: 1) retention time: matrine t is about 9.1min, bergenin t is about 19.1min, and trifolium red sandalwood glycoside t is about 46.5min, which is basically unchanged; 2) linear regression equation: matrine y ═ 21238x-44.457 and R 2 0.9999, bergenin y 27577x +86.624 and R 2 0.9997, pterocarpus santalin y 93253x-34.145 and R 2 0.9998; 3) KHJ20190127 precision of 20190127 test sample: the mean values of the areas of the matrine and the bergenin are 1380561 and 0.25 respectively, 2924216 and 0.22 respectively, 607144 and 0.35 respectively; 4) KHJ20190127 24h stability test of 20190127 test article: the mean values of the areas of the matrine and the bergenin are 1380268 and 0.33 respectively, 2923523 and 0.41 respectively, 604327 and 0.38 respectively; 5) KHJ20190127 repeatability test of 20190127 test article: the mean values of the areas of the matrine and the bergenin are 1372084, 0.51%, 2908473 and 0.43%, 602836 and 0.62%; 6) KHJ20190127 sample application recovery test of 20190127 test: the average recovery rate of three concentrations of matrine is 99.64% and RSD is 1.33%, the average recovery rate of three concentrations of bergenin is 101.46% and RSD is 1.26%, and the average recovery rate of three concentrations of trifolium pterocarpus santalin is 101.84% and RSD is 1.64%; 7) the content (mug/ml) of matrine, bergenin and red sandalwood glycoside of 5 batches of fenugreek sprays is simultaneously measured, and the result is that: KHJ20190127 the contents of the three components are 324.4 μ g/ml, 530.9 μ g/ml, 32.3 μ g/ml, KHJ2019The contents of three components of 0610 are respectively 332.2 mu g/ml, 525.6 mu g/ml and 32.6 mu g/ml, the contents of three components of KHJ20190816 are respectively 326.7 mu g/ml, 535.5 mu g/ml and 32.5 mu g/ml, the contents of three components of example 1 are respectively 329.4 mu g/ml, 531.4 mu g/ml and 32.4 mu g/ml, the contents of three components of example 2 are respectively 412.5 mu g/ml and 661.3 mu g/ml, 41.3 mu g/ml, 367.8 mu g/ml, 595.7 mu g/ml and 37.2 mu g/ml for the three components in example 3, 288.3 mu g/ml, 464.5 mu g/ml and 28.6 mu g/ml for the three components in example 4, and 430.5 mu g/ml, 695.3 mu g/ml and 43.4 mu g/ml for the three components in example 5.
