Tripterine is red needle crystal, fusing point 185-200 ℃, is dissolved in methyl alcohol, ethanol, acetone, ETHYLE ACETATE, chloroform etc.; Be insoluble in water; Modern medicine study shows that it has very strong antioxygenation, and anticancer disease new vessel nucleus formation is arranged; The resisting rheumatoid disease effect is arranged, spermicide effect etc. is arranged.
Trypterygine is the Celastraceae plant, and root, leaf, flower and fruit are used as medicine, and have and dispel rheumatism, and be promoting blood circulation and removing obstruction in channels, swelling and pain relieving, desinsection detoxification.
Existing Tripterine preparation technology has:
The method that this patent of patent " a kind of method for preparing Tripterine " adopts is utilization chloroform ultrasonic extraction, solvent pairs eluting silica gel column chromatography and mixed solvent recrystallization etc.
Patent " a kind of preparation method of celastrin ", this patent disclosed method are to get Celastraceae plant root of Panicled Bittersweet root skin, pulverize, and add the methyl alcohol that its quality 4-5 doubly measures volume; Insert in the ultrasonic extraction device supersound extraction 1-3 time, united extraction liquid filters reclaim under reduced pressure methyl alcohol; Residue adds the alkali aqueous solution dissolving, filters, and filtrating is regulated the pH value to 3-5 with the Hydrogen chloride acid solution, leaves standstill; Filter, get filter residue, join on the alumina chromatographic column, the use volume ratio is methyl alcohol-chloroform mixed solvent wash-out of 3: 1; Collect the elutriant that 2-4 doubly measures column volume, decompression and solvent recovery also concentrates, and adding volume ratio is 1; 1 ethanol-normal hexane mixed solvent crystallization, fractional crystallization promptly gets.
Patent " a kind of method of in the Root of Oriental Bittersweet skin, extracting Tripterine ", this special disclosed method be for being solvent with rudimentary chloroparaffin, heating and refluxing extraction; The mass ratio of root skin powder and solvent 1: 3～20; Time is no less than 2 hours, obtains medicinal extract shape primary extract behind the extracting solution precipitation, in primary extract, adds 50～70% methyl alcohol or ethanolic soln then; Fully stir, leave standstill extraction, obtain thick paste shape crude extract behind the extraction liquid precipitation; Described purifying is to use the column chromatography separating purification of stationary phase as purification on normal-phase silica gel or reverse phase silica gel after crude extract uses dissolve with methanol, collects elutriant, obtains Powdered extract after the precipitation drying, uses the ethanol-water mixed solvent recrystallization at last.
Document " is used the preparation of novel vertical adverse current chromatogram and is separated the celastrin in the Stem of Oriental Bittersweet ", and the document adopts high speed adverse current chromatogram to prepare Tripterine.
As stated, mostly existing technology is to adopt column chromatography or preparation liquid phase at the preparation Tripterine, and preparation amount is less, and industrialization degree is low.
Summary of the invention:
The technical problem that present method will solve provides a kind of preparation method of Tripterine, and this method is easy to industriallization, and products obtained therefrom content is high.
In order to realize above-mentioned purpose of the present invention, the invention provides following technical scheme:
A kind of preparation method of Tripterine is characterized in that may further comprise the steps: get tripterygium root and pulverize, add 5-7 and doubly measure the 85-90% alcohol reflux 2-3 time, extracting solution adds activated carbon decolorizing; Destainer reclaims ethanol to determining alcohol 55-65%, places deposition, and throw out leaches, and doubly measures the alkaline alcohol solution dissolving with 5-7; Leach insolubles, regulate pH3-5, place deposition, leach deposition; Doubly measure the alkaline alcohol dissolving with 3-5 again, filter and regulate the neutral deposition of placing of pH, leach deposition; The ethyl acetate backflow dissolving is filtered, and places crystallization; Crystallisate leaches and adds activated carbon decolorizing with the dissolving of 90-95% alcohol reflux, destainer insulation crystallization, and crystallisate is drying to obtain the pure article of Tripterine.
Described alkaline alcohol is the ethanolic soln (containing sodium hydroxide 0.4-0.8%) of 70-85%.
The used acid of said adjusting pH is concentrated hydrochloric acid.
50-55 ℃ of described insulation Tc.
Advantage of the present invention is:
1) adopt extraction using alcohol, alcohol toxicity is little, and higher than the methanol extraction content under the equal conditions, is prone to purifying, and is lower than chloroform extraction cost;
2) adopt lower concentration alcohol deposition, can remove solvent components in the low alcohol, shortened the production cycle and reduced production cost;
3) adopting dissolving of twice alkali alcohol and insulation crystallization, is to utilize triterpene acids and alkali to combine solubleness to become big, and the character that acid adjustment is separated out is again removed low polar material;
4) whole technological operation is simple, and facility investment is less, and industrialization degree is high.
