Abstract

The invention belongs to the technical field of traditional Chinese medicines, and particularly relates to a preparation method and application of a fukean tablet. The preparation method of the fukean tablet is as follows: the fukean tablet is prepared from 1000 g of jasminum elongatum, 1000 g of Chinese knotweed, 670 g of ovate leaf holly bark, 330 g of plantain herb and 330 g of pomegranate peel as raw materials by use of microwave extraction and macroporous resin adsorption, and the total flavonoid content is greatly improved. The invention also provides application of the fukean tablet in preparation of drugs for inhibition of cell proliferation of mouse embryonic carcinoma cell P19.

Description

A kind of preparation method of fukean tablet and the application in preparation suppression mouse teratocarcinoma cells P19 cell proliferation thereof
Technical field
The invention belongs to technical field of Chinese medicines, be specifically related to a kind of preparation method of fukean tablet and suppress the application in mouse teratocarcinoma cells P19 cell proliferation in preparation.
Background technology
Fukean tablet standard No. WS-10256(ZD-0256)-2002, be recorded in national standard for traditional Chinese medicines compilation internal medicine taste fascicle.Be made up as crude drug of Herba Oxalidis strictae 1000g, Herb Polygoni Chinensis 1000g, Cortex Ilicis Rotundae 670g, Herba Plantaginis 330g, Pericarpium Granati 330g, there is clearing away heat-damp and promoting diuresis, convergence, effect of pain relieving.The stomachache caused for acute gastroenteritis, dyspepsia, diarrhoea, vomiting.
In prior art, fukean tablet is not yet had to extract the report adopting microwave technology and macroporous resin adsorption extractive technique in preparation, and decocting in water alcohol extraction, technique is coarse, backward, and impurity is many, causes patient's consumption excessive, be inconvenient to take, had a strong impact on this product and applied clinically.
In prior art, fukean tablet is oral, one time 4,3 times on the one.Fukean tablet dosage is large.The heavy 0.3g of the every sheet of the fukean tablet 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.
The comparison of general flavone content in fukean tablet prepared by test one, distinct methods
L, instrument and reagent fukean tablet of the present invention: by the preparation of embodiment 1 method, use 3330g crude drug, makes 500 through extracting, the heavy 0.3g of every sheet.Former fukean tablet, according to WS-10256(ZD-0256)-2002 standard method preparations, in contrast.Visible-ultraviolet light microwell plate detector (MD company of U.S. model: SPECTRAMAX190); METTLER AE240 electronic analytical balance; Control substance of Rutin (Nat'l Pharmaceutical & Biological Products Control Institute).
2, method
The preparation precision of reference substance solution takes at 120 DEG C of drying under reduced pressure appropriate to the control substance of Rutin of constant weight, adds 60% ethanol and makes the solution of every 1ml containing 0.1mg, to obtain final product.
The preparation precision of standard curve measures reference substance solution 1.0ml, 2.0ml, 3.0ml, 4.0ml, 5.0ml, put in 25ml measuring bottle respectively, respectively add 10% sodium nitrite solution 0.3ml, mixing, places 6 minutes, add 10% aluminum nitrate solution 0.3ml, mixing, places 6 minutes, add 4% sodium hydroxide solution 4ml, shake up, add 30% ethanol to scale, shake up, place 15 minutes; With corresponding solution for blank.According to spectrophotography (Chinese Pharmacopoeia version in 2000 annex V B) test, measure trap at 510nm wavelength place, take trap as vertical coordinate, concentration is abscissa, drawing standard curve.
Algoscopy gets this product under weight differential item, removing coating, porphyrize, (fukean tablet prepared of the inventive method gets 0.125g in sampling, former fukean tablet takes 0.2g), accurately weighed, put in round-bottomed flask, add methanol 25ml, shake up, reflux 1 hour, take out, be cooled to room temperature, filter, filter paper adds methanol 25ml again together with residue, reflux 1 hour, take out, cooling, filter, merging filtrate, residue methanol 15ml gradation is washed, washing liquid and filtrate merge, evaporate to dryness, residue adds 60% alcoholic solution makes dissolving, to be transferred in 50ml measuring bottle and to be diluted to scale, shake up.Precision measures 1ml, method under sighting target directrix curve preparation, from " putting respectively in 25ml measuring bottle ", measures trap in accordance with the law, reads the weight of rutin in need testing solution from standard curve, calculates, to obtain final product.
3, result
Result shows, in fukean tablet of the present invention, the content of total flavones counts 80-100mg/ sheet with rutin; And the content of total flavones counts 10.54mg/ sheet with rutin in former fukean tablet, every sheet rutin content is equivalent to the 8-10 of former tablet content doubly, and when dose reduces, general flavone content improves a lot.
Above-mentioned research shows, adopt fukean tablet prepared by preparation method of the present invention, active constituent content is far away higher than WS-10256(ZD-0256) fukean tablet prepared of method recorded of-2002 standards.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of preparation method of fukean tablet.
Another object of the present invention is to provide a kind of fukean tablet to suppress the application in mouse teratocarcinoma cells P19 cell proliferation in preparation.
The object of the invention is by following scheme realize:
