In the prior art, not yet there is a kind of reed mentioned in ancient books to adopt the report of supercritical and microwave technology aspect the preparation extracting in flakes, and adopts the method that powder and decocting boil of beating, 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 used clinically.
Summary of the invention
Goal of the invention: in order to address the above problem, the object of the present invention is to provide a kind of a kind of reed mentioned in ancient books preparation method in flakes.
Another object of the present invention is to provide the in flakes application in preparation inhibition mouse myeloma SP2/0 cell proliferation medicine of a kind of a kind of reed mentioned in ancient books.
Technical scheme: the objective of the invention is to realize by following scheme:
A kind of a kind of reed mentioned in ancient books preparation method in flakes, made as crude drug by Radix Scutellariae 250g, Fructus Forsythiae 250g, Rhizoma Coptidis 100g, Cortex Phellodendri 400g, Radix Paeoniae Rubra 250g, Radix Glycyrrhizae 100g, described method is comprised of the following step: get Fructus Forsythiae, join in the CO2 supercritical extraction device, ethanol is as entrainer, and the percent by volume that entrainer accounts for total extractant is 4-6%, extracting pressure 15-30MPa, temperature 30-50 ℃, CO 2Flow 1-3m1/g crude drug min, extraction time 150-180min gets supercritical extract, and is for subsequent use; Get all the other Chinese medicines, pulverize, add 70% ethanol of 2L, drop in the microwave extracting apparatus and carry out microwave extracting, extraction power 400-600W extracts 2 times, each 4-8 minute, combining extraction liquid, concentrated, be added on the D101 macroporous adsorptive resins, 50% ethanol elution is collected 5 times of amount column volume eluents, decompression recycling ethanol, concentrated and dry, get the microwave extraction thing, for subsequent use; Above-mentioned supercritical extract and microwave extraction thing are mixed, add starch, 70% ethanol granule processed, drying, tabletting is made 1000, every heavy 0.5g.
Above-mentioned a kind of a kind of reed mentioned in ancient books preparation method in flakes, described CO 2The percent by volume that the supercritical extraction entrainer accounts for total extractant is 5%.
Above-mentioned a kind of a kind of reed mentioned in ancient books preparation method in flakes, described microwave extracting power 500W extracts 6 minutes at every turn.
Above-mentioned a kind of a kind of reed mentioned in ancient books preparation method in flakes, described CO 2The extracting pressure 20MPa of supercritical extraction, 40 ℃ of temperature, CO 2Flow 2ml/g crude drug min, extraction time 160min.
Above-mentioned a kind of reed mentioned in ancient books is the application in preparation inhibition mouse myeloma SP2/0 cell proliferation medicine in flakes.
In the prior art, a kind of reed mentioned in ancient books is every 0.55g in flakes, and each 4,2-3 time on the one, adopt in flakes every 0.5g of a kind of reed mentioned in ancient books that the present invention is prepared into, only need 2 at every turn, took 2 times in 1st, greatly reduced dose having under the condition of more active component.This conclusion can be by following evidence.
The in flakes comparison of middle baicalin content of a kind of reed mentioned in ancient books of test one, distinct methods preparation
1, instrument and reagent a kind of reed mentioned in ancient books of the present invention in flakes: press the preparation of embodiment 3 methods, use the 1350g crude drug, make 1000 through extraction, every heavy 0.5g.Former a kind of reed mentioned in ancient books by the preparation of ministry standard method, uses the 1350g crude drug in flakes, makes 1175 through extraction, every heavy 0.55g.The Agilent1200 high performance liquid chromatograph; METTLER AE240 electronic analytical balance; Baicalin reference substance (Nat'l Pharmaceutical ﹠ Biological Products Control Institute).
2, method
Chromatographic condition and system suitability: be filler with octadecylsilane chemically bonded silica; Methanol-water-phosphoric acid (40:60:0.2) is mobile phase; The detection wavelength is 280nm.Number of theoretical plate is pressed the baicalin peak and is calculated, and should be not less than 3000.
The preparation of reference substance solution: precision takes by weighing at 4 hours baicalin reference substance of 60 ℃ of drying under reduced pressure an amount of, adds methanol and makes the solution that every 1ml contains 18 μ g, and get final product.
The preparation of need testing solution: get a kind of reed mentioned in ancient books of the present invention in flakes with former a kind of reed mentioned in ancient books in flakes, porphyrize, mixing is got 1g, and is accurately weighed, the accurate 70% ethanol 20ml that adds, close plug, supersound process 10 minutes, centrifugal, get supernatant, and get final product.
Algoscopy is accurate reference substance solution and each 20 μ l of need testing solution of drawing respectively, and the injection liquid chromatography is measured, and be get final product.
3, result
