Description
Technical field
The invention belongs to technical field of Chinese medicines, be specifically related to a kind of preparation method of Fructificatio Fomitopsis Officinalis cough with asthma sheet and suppressing the application in mouse lymphoma cell EL4 cell proliferation.
Background technology
Fructificatio Fomitopsis Officinalis Kechuan oral liquid standard No. WS-10245 (ZD-0245)-2002, is recorded in national standard for traditional Chinese medicines compilation internal medicine lung system fascicle.Be made up as crude drug of Fructificatio Fomitopsis Officinalis 20g, european plum 100g, Rhizoma Phragmitis 80g, Radix Glycyrrhizae 60g, Herba Ephedrae 50g, Radix Aucklandiae 30g, anisum fruit 120g, Rhizoma Cyperi 30g, Fructus Amomi Rotundus 20g, there is cough-relieving, relieving asthma, the effect of eliminating the phlegm.For cold cough, cough up phlegm not well, acute/chronic bronchitis, asthma.
In prior art, Fructificatio Fomitopsis Officinalis Kechuan oral liquid is not yet had to extract the report adopting supercritical extraction and microwave extraction technology in preparation, and volatile oil is drawn, the method of water heating extraction, technique is coarse, backward, and impurity is many, causes patient's consumption very large, be inconvenient to take, had a strong impact on this product and applied clinically.
In prior art, each 10ml of Fructificatio Fomitopsis Officinalis Kechuan oral liquid, 3 times on the one.Fructificatio Fomitopsis Officinalis Kechuan oral liquid is oral liquid because of it, and taste is more bitter, is not suitable for child administration, and in addition, if seasoning needs sugaring many, uncomfortable diabetic to take, patient compliance is poor.The heavy 0.3g of the every sheet of the Fructificatio Fomitopsis Officinalis cough with asthma sheet adopting the inventive method to be prepared into, only needs 2 at every turn, within 1st, takes 3 times.Dose is greatly reduced under the condition with more active component.This conclusion can be proved by following test.And being prepared into tablet, patient swallows with water, and dosage is little and without bitterness, patient is easy to accept.
The comparison of glycyrrhizic acid content in Fructificatio Fomitopsis Officinalis cough with asthma sheet prepared by test one, distinct methods
L, instrument and reagent Fructificatio Fomitopsis Officinalis cough with asthma of the present invention sheet: by the preparation of embodiment 1 method, use 560g crude drug, makes 200 through extracting, the heavy 0.3g of every sheet.Former Fructificatio Fomitopsis Officinalis Kechuan oral liquid, prepares according to WS-10245 (ZD-0245)-2002 standard method.Agilent1200 high performance liquid chromatograph; METTLER AE240 electronic analytical balance; Glycyrrhizic acid reference substance (Nat'l Pharmaceutical & Biological Products Control Institute).
2, method
Measure according to high performance liquid chromatography (Chinese Pharmacopoeia version in 2010 annex VI D).
Chromatographic condition and system suitability octadecyl silane are filler; Methanol-0.2mol/L Spirit of Mindererus .-glacial acetic acid (67: 33: 1) is mobile phase; Determined wavelength is 250nm.Number of theoretical plate calculates should be not less than 2000 by monoammonium glycyrrhizinate peak.
The preparation precision of reference substance solution takes monoammonium glycyrrhizinate reference substance 10mg, puts in 50ml measuring bottle, dissolves and be diluted to scale, shake up with mobile phase, obtains (containing monoammonium glycyrrhizinate reference substance 0.2mg, amount to glycyrrhizic acid is 0.1959mg to every 1ml).
Fructificatio Fomitopsis Officinalis cough with asthma sheet of the present invention is got in the preparation of Fructificatio Fomitopsis Officinalis cough with asthma sheet need testing solution of the present invention, and porphyrize, gets 0.6g, accurately weighed, put in tool plug conical flask, the 10ml that adds water makes dissolving, solution filters, precision measures 2ml filtrate, moves in evaporating dish, evaporate to dryness, residue adds the flowing mutual-assistance and dissolves, move in 10ml measuring bottle, add mobile phase to scale, to obtain final product.
The Fructificatio Fomitopsis Officinalis Kechuan oral liquid of contrast is got in the preparation of reference product need testing solution, and precision measures 2ml, moves in evaporating dish, evaporate to dryness, and residue adds the flowing mutual-assistance and dissolves, and moves in 10ml measuring bottle, adds mobile phase to scale, to obtain final product.
Algoscopy is accurate respectively draws reference substance solution and each 10 μ l of need testing solution, injection liquid chromatography, measures, shakes up, to obtain final product.
3, result
Result shows, in Fructificatio Fomitopsis Officinalis cough with asthma sheet of the present invention, the content of glycyrrhizic acid is 3.6-7.2mg/ sheet; And the content of glycyrrhizic acid is 0.36mg/ml in former Fructificatio Fomitopsis Officinalis Kechuan oral liquid, the glycyrrhizic acid content each serving consumption 2 is 2-4 times of original oral liquid agent content, and when dose reduces, glycyrrhizic acid content improves a lot.
Above-mentioned research shows, adopts Fructificatio Fomitopsis Officinalis cough with asthma sheet prepared by preparation method of the present invention, Fructificatio Fomitopsis Officinalis Kechuan oral liquid prepared by the method that active constituent content is recorded higher than WS-10245 (ZD-0245)-2002 standard far away.
