Description
Technical field
The invention belongs to technical field of Chinese medicines, be specifically related to a kind of preparation method of Huang-Xuan-Yi-gan sheet and suppress the application in mouse prostate cancerous cell RM-1 cell proliferation in preparation.
Background technology
Liver benefiting Huangxuan Yigan Powder standard No. WS-10465(ZD-0465)-2002, be recorded in national standard for traditional Chinese medicines compilation internal medicine liver and gall fascicle.Be made up as crude drug of Radix Rumicis 291g, Hemerocallis fulva L. 103g, Herba Senecionis Scandentis 92g, Fructus actinidiae chinensis 92g, Rhizoma et Radix smilacis ocreatae 92g, Flos rosae multiflorae 62g, Herba Swertiae bimaculatae 62g, Radix Pimpinellae Candolleanae 62g, Fructus Schisandrae Sphenantherae 62g, there is heat-clearing and toxic substances removing, effect of depressed liver-energy dispersing and function of gallbladder promoting.For the chronic hepatitis B caused by dampness-heat in the liver and gallbladder.
In prior art, not yet there is Huang-Xuan-Yi-gan to be dispersed in and extract preparation aspect employing CO
2the report that supercritical extraction, microwave technology and macroporous adsorption resin technology extract, and the method that powder is got directly beaten by Chinese medicine, technique is coarse, backward, and impurity is many, causes patient's consumption excessive, is inconvenient to take, and has had a strong impact on this product and has applied clinically.
In prior art, liver benefiting Huangxuan Yigan Powder is oral, and be grown up a 9g, 3 times on the one.Liver benefiting Huangxuan Yigan Powder dosage is large.The heavy 0.5g of the every sheet of the Huang-Xuan-Yi-gan 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.
The comparison of emodin content in Huang-Xuan-Yi-gan sheet prepared by test one, distinct methods
L, instrument and reagent Huang-Xuan-Yi-gan sheet of the present invention: by the preparation of embodiment 1 method, use 918g crude drug, makes 200 through extracting, the heavy 0.5g of every sheet.Former liver benefiting Huangxuan Yigan Powder, according to WS-10465(ZD-0465)-2002 standard method preparations, in contrast.Agilent1200 high performance liquid chromatograph; AE240 electronic analytical balance; Emodin 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 octadecylsilane chemically bonded silica are filler; Methanol-0.25% phosphoric acid solution (80: 20) is mobile phase; Determined wavelength is 436nm.Number of theoretical plate calculates should be not less than 3000 by emodin peak.
The preparation of reference substance solution is learnt from else's experience, and to be dried to the emodin reference substance of constant weight appropriate, accurately weighed for phosphorus pentoxide, adds methanol and make the solution of every 1ml containing 0.05mg, to obtain final product.
Huang-Xuan-Yi-gan sheet of the present invention is got in the preparation of product need testing solution of the present invention, and porphyrize, gets 0.4g, accurately weighed, put in apparatus,Soxhlet's, add appropriate amount of ethanol, heating and refluxing extraction is to colourless, and extracting solution is concentrated into about 5ml, lets cool, add dilute hydrochloric acid 5ml, chloroform 30ml, reflux 30 minutes, lets cool, divide and get chloroform solution, the jolting of water liquid chloroform is extracted 2 times (20ml, 15ml), combined chloroform liquid, evaporate to dryness, residue adds methanol to be made dissolving and moves in 10ml measuring bottle, add methanol dilution to scale, shake up, centrifugal, get supernatant, to obtain final product.
The liver benefiting Huangxuan Yigan Powder of this contrast, porphyrize are got in the preparation of reference substance need testing solution, mixing, get 2g, accurately weighed, put in apparatus,Soxhlet's, add appropriate amount of ethanol, heating and refluxing extraction is to colourless, and extracting solution is concentrated into about 5ml, let cool, add dilute hydrochloric acid 5ml, chloroform 30ml, reflux 30 minutes, let cool, divide and get chloroform solution, the jolting of water liquid chloroform is extracted 2 times (20ml, 15ml), combined chloroform liquid, evaporate to dryness, residue adds methanol to be made dissolving and moves in 10ml measuring bottle, adds methanol dilution to scale, shake up, centrifugal, get supernatant, to obtain final product.
Algoscopy is accurate respectively draws each 10 μ l of reference substance solution, product need testing solution of the present invention and reference substance need testing solution, injection liquid chromatography, measures, to obtain final product.
3, result
Result shows, in Huang-Xuan-Yi-gan sheet of the present invention, the content of emodin is 2-4mg/ sheet; And the content of emodin is 0.21mg/ grain in former liver benefiting Huangxuan Yigan Powder, every sheet emodin content is equivalent to the 10-20 of powder every g powder content doubly, and when dose reduces, emodin content improves a lot.
Above-mentioned research shows, adopt Huang-Xuan-Yi-gan sheet prepared by preparation method of the present invention, active constituent content is far away higher than WS-10465(ZD-0465) liver benefiting Huangxuan Yigan Powder prepared of method recorded of-2002 standards.
