4-6%, extracting pressure 15-30MPa, temperature 30-50 DEG C, CO2Flow l-3ml/g crude drug min, extraction time 800-
1000min, obtains supercritical extract, and supercritical extract is added starch, 70% ethanol granule, is dried, tabletting, makes 500
Sheet, every tablet weight 0.30g.
Preferably, above-mentioned Tianhusui Yugan tablets is in preparation suppression small cell lung cancer cell LTEP-P cell proliferation
Application, the preparation method of described Tianhusui Yugan tablets comprises the steps: to take Herba Hydrocotyles 699g, Radix Pimpinellae Candolleanae 1398g, jealous woman slurry
Grass 699g, Radix Anemones Rivularis 209g, join CO2In supercritical extraction device, ethanol is as entrainer, and entrainer accounts for total extractant
Percent by volume is 5%, extracting pressure 25MPa, temperature 40 DEG C, CO2Flow 2ml/g crude drug min, extraction time 900min,
Supercritical extract, adds starch by supercritical extract, 70% ethanol granule, is dried, tabletting, makes 500, every tablet weight
0.30g。
In prior art, Tianhusui Yugan tablets be administered orally, one time 6,3 times on the one.Tianhusui Yugan tablets dosage is big.Use
Every tablet weight 0.30g of Tianhusui Yugan tablets that the inventive method is prepared as, the most only needs 3, within 1st, takes 3 times.More having
Dose is greatly reduced under conditions of active component.This conclusion can be proved by following test.
The comparison of content of oleanolic acid in Tianhusui Yugan tablets prepared by test one, distinct methods
L, instrument and reagent Tianhusui Yugan tablets of the present invention: prepare by embodiment 1 method, uses 3005g crude drug, extracted system
Become 500, every tablet weight 0.30g.Former Tianhusui Yugan tablets, according to WS-10213(ZD-0213) prepared by-2002 standard methods.
Agilent1200 high performance liquid chromatograph;METTLER AE240 electronic analytical balance;(China's medicine is raw for oleanolic acid reference substance
Tetramune examines and determine institute).
2, method
Measure according to high performance liquid chromatography (Chinese Pharmacopoeia the 4th note on the use 15 of version in 2015).
Chromatographic condition and system suitability octadecylsilane chemically bonded silica are filler;Acetonitrile-0.1% phosphorus
Acid (80:20) is flowing phase;Detection wavelength is 210nm.Number of theoretical plate is calculated by oleanolic acid peak should be not less than 3000.
It is appropriate that the preparation precision of reference substance solution weighs oleanolic acid reference substance, adds methanol and makes every 1ml containing 0.2mg's
Solution, to obtain final product.
The preparation of the Tianhusui Yugan tablets need testing solution of the present invention takes the Tianhusui Yugan tablets of the present invention, finely ground, takes
The amount of 0.75g(2.5 sheet), accurately weighed, put in tool plug conical flask, the accurate ethanol 25ml that adds, close plug, weighed weight, heating
Reflux 1 hour, let cool, more weighed weight, to supply the weight of less loss with ethanol, shake up, filter, precision measures subsequent filtrate 10ml,
Adding 20% hydrochloric acid solution 5ml, be heated to reflux 2.5 hours, add water 30ml, water-bath is concentrated into without alcohol taste, lets cool, uses dichloromethane
3 times (40ml, 30ml, 30ml), combined dichloromethane extracting solution are extracted in shaking, are evaporated, and residue adds methanol makes dissolving in right amount, transfer
To 10ml measuring bottle, add methanol dilution to scale, shake up, to obtain final product.
The preparation of reference product need testing solution takes the Tianhusui Yugan tablets 20g of comparison, finely ground, takes 1.5g(5 sheet
Amount), accurately weighed, put in tool plug conical flask, accurate addition ethanol 25ml, close plug, weighed weight, it is heated to reflux 1 hour, puts
Cold, more weighed weight, to supply the weight of less loss with ethanol, shake up, filter, precision measures subsequent filtrate 10ml, adds 20% hydrochloric acid molten
Liquid 5ml, is heated to reflux 2.5 hours, and add water 30ml, water-bath is concentrated into without alcohol taste, lets cool, and extracts 3 times with dichloromethane shaking
(40ml, 30ml, 30ml), combined dichloromethane extracting solution, it is evaporated, residue adds methanol makes dissolving in right amount, is transferred to 10ml measuring bottle
In, add methanol dilution to scale, shake up, to obtain final product.
Algoscopy respectively precision is drawn the Tianhusui Yugan tablets need testing solution of reference substance solution and the present invention, is compareed product
The each 10 μ l of product need testing solution, inject chromatograph of liquid, measure, to obtain final product.
3, result
Result shows, in Tianhusui Yugan tablets of the present invention, the content of oleanolic acid is 3.22-6.45mg/ sheet;And former Herba Hydrocotyles is more
In liver slice, the content of oleanolic acid is 0.81mg/ sheet, and the content of oleanolic acid each serving consumption 3 is former 6 content of tablet
2-4 times, in the case of dose reduces, content of oleanolic acid improves a lot.
The studies above shows, uses Tianhusui Yugan tablets prepared by preparation method of the present invention, and active constituent content is the highest
In WS-10213(ZD-0213) Tianhusui Yugan tablets prepared of method recorded of-2002 standards.
