Abstract
The present invention relates to a clean producing technology of kurarinol, which uses matrine as raw materials. The technology comprises the procedures of oxidation, quenching, matrine recovering by extraction, concentration, redissolution in a polar solvent, filtration, concentration and crystallization, separation and baking, and crude product refining. In the procedure of the matrine recovering by extraction, a nonpolar organic solvent is used to extract residual matrine in oxidation reaction liquid, and then the extracted liquid returns to the oxidation procedure. Mother liquid separated in the concentration and crystallization procedure return to the procedure of matrine refining. In the quenching procedure, a catalyst for terminating the reaction is added in the oxidation reaction liquid, and the catalyst is a reducing compound. Compared with the prior art, the present invention has the advantages of simpler technology, shorter production period (1/3 of the original period) and higher product yield. The product yield of the prior art is about 50%, while the product yield of the present invention can reach over 80%. Corresponding production efficiency is greatly improved, and additionally no waste liquid is discharged in the whole production process.
Description
Technical field:
The invention belongs to the Chinese herbal medicine extracting processing technique field, particularly use the method for the matrine production kurarinone that from Herba Sophorae alopecuroidis, extracts, a kind of clean kurarinol producing process.
Background technology:
Kurarinone is a kind of alkaloid that extracts preparation from the Chinese medicine Herba Sophorae alopecuroidis, and wherein Oxymatyine (oxymatrine) accounts for more than 98%, and molecular formula is C
15H
24N
2O
2H
2O, molecular weight are 282, and other also have the sophocarpine of minute quantity.Clinical study shows: kurarinone has direct anti-hepatitis B virus effect, has the collagen mobility of inhibition and fibrosis effect in the time of Oxymatyine treatment chronic hepatitis.Oxymatyine also has antianaphylaxis, anti-inflammatory action: can regulate immunity and leukocyte increasing; In December, 1996 is by the specified attached Huashan hospital of medical university of going up of the Ministry of Health, Beijing You An hospital finishes 40 routine randomized, double-blind checking and other basic demonstrations about drug effect, untoward reaction, and Ministry of Health's approval on February 24th, 1998 Oxymatyine is country's treatment chronic hepatitis B five kind new medicines; In August, 1998 China medical association emphasis popularization engineering specialist authenticates decision and lists the Treated by Oxymatrine Injection viral hepatitis in emphasis popularization engineering project, promotes the use of in the whole nation;
At present kurarinone how adopts with the matrine that to be raw material synthesize through processing steps such as oxidation, extraction, concentrated, backflow, suction filtrations; In all disclosed patent documentations, all used excessive hydrogen peroxide oxidant, as number of patent application 96109730.2 and 00109240.5 patent of invention bulletin; Facts have proved: excessive hydrogen peroxide is not as removing, can make in the product kurarinone remaining content of hydrogen peroxide too high, has toxicity, can not use as bulk drug, and alkaline matter decomposition of hydrogen peroxide such as use sodium hydroxide, when temperature is hanged down, reaction times is longer, by product was a lot of when temperature was high, caused the aftertreatment difficulty, and product yield reduces.
Summary of the invention:
The objective of the invention is to overcome the prior art defective provides a kind of technology simple, easy and simple to handle, and production cost is lower, productive rate height, the clean kurarinol producing process that no discharging of waste liquid is circulating.
Purpose of the present invention realizes by following scheme:
Clean kurarinol producing process, with the matrine is raw material, technological process is: oxidation, cancellation, extraction are reclaimed matrine, are concentrated, heavy molten, the filtration of polar solvent, condensing crystal, separation oven dry, crude product refining, it is that extraction liquid returns oxidation section with remaining matrine in the non-polar organic solvent extraction oxidation liquid that the matrine process is reclaimed in extraction; The isolated mother liquor of condensing crystal returns the refining workshop section of matrine;
Above-mentioned cancellation process is the catalyzer that adds termination reaction in oxidation liquid, and this catalyzer is a reducing compound;
The used oxygenant of above-mentioned oxidising process is a hydrogen peroxide, and the weight proportion of matrine and the reaction of industrial hydrogen peroxide is: 1: 0.8-1.0;
Above-mentioned non-polar organic solvent is ether, sherwood oil or benzene kind solvent;
Above-mentioned reducing compound is sodium sulphite, Sulfothiorine, S-WAT or sodium iodide, and addition is the 0.5-2% of the used weight of matrine.
Above-mentioned polar organic solvent is an alcoholic solvent.
The present invention compared with prior art, technology is simpler, the production cycle is shorter, be 1/3 of primitive period, product yield height, prior art products yield about 50%, the present invention can reach more than 80%, and corresponding production efficiency improves a lot, and production whole process does not in addition have discharging of waste liquid.
