Description
Technical field
The present invention relates to a kind of method of producing high purity matrine oxide.
Technical background
Kuh-seng and Herba Sophorae alopecuroidis all are rich in Radix Sophorae Flavescentis alkaloid class and bioflavonoid active ingredient, present research mainly concentrates on the Radix Sophorae Flavescentis alkaloid aspect, Radix Sophorae Flavescentis alkaloid is to be the similar alkaloid of a class chemical structure of representative with the matrine, 23 kinds of alkaloids have now been isolated, comprise matrine, Oxymatyine, sophocarpine, Sophocarpidin, sophoranol, sophorine, Anagyrine, Ba Puye alkali, sophoranole etc., sophocarpidine has multiple physiologically active, for hepatitis, viral myocarditis, tumours etc. all have restraining effect, also have broad application prospects in field of biological pesticide.Bureau of Drugs Supervision of country has proposed higher standard for medicinal matrine, Oxymatyine, all requires purity greater than 98.0%, and this purification technique for the matrine series product is a challenge.
Patent of invention " bitter beans comprehensive use " is (CN85108322A) by the bitter beans detoxification of acid treatment, again with acid solution with alkaloid back extraction successively, but various alkaloidal physicochemical property are very approaching, rely on the adjusting of pH value to be difficult to obtain high purity product merely; Patent of invention " utilizes transfer hydrogenation to be prepared the method for matrine by sophocarpine " (ZL00118510.1) by hydrazine hydrate and sophocarpine prepared in reaction matrine in the presence of oxygen, but separating of high purity sophocarpine own and matrine purified with regard to existing problems, because the existence of Oxymatyine and sophocarpine, gained matrine product purity is inevitable limited; Patent of invention " preparation technology of ALOPERINE " (CN00136814.1) (CN1368502A) directly extracts by sophora alapecuroides liquid with " preparation technology of sophora alapecuroides ", obtain the ALOPERINE crude product, recrystallization obtains purity greater than 98% ALOPERINE, this process can not realize the separation of matrine, Oxymatyine, sophocarpine, Sophocarpidin, sophoranol etc., so 98% purity should be the content of biology total alkali, rather than the product of single chemical composition; Patent of invention " adopts the CO2 supercritical extraction technique to prepare the method for aqueous matrine solution and matrine pulvis " and (CN02103757.4) obtains content less than the former powder of 50% matrine by supercritical extraction, but Ge Fahuan (Chinese medicinal materials, 2003,426) etc. 26 (6): the people's studies show that under the condition without entrainment agent, supercritical co almost can not extract for matrine, it is also undesirable to add ethanol entrainment agent effect of extracting, need or introduce nonionogenic tenside by the ammoniacal liquor alkalization and just can obtain higher yield, but ammoniacal liquor has stronger corrosive nature to overcritical device, and tensio-active agent be separating fully of product one than complicated problems.
By tubular fibre membrane ultrafiltration (Zhengzhou Engineering College's journal, 2003,56), Zeo-karb (Xibei Forest College's journal 24 (4):, 113), micro-filtration-Amberlyst process (ACAD J GCP, 2,003 2004,11 (1):, 334), resin purification-column chromatography (extracts the production method of matrine from Herba Sophorae alopecuroidis 19 (4):, CN1583743A) the alkaloidal report of separating matrine-like is a lot, but all has the running cost height, the problem that production lot is little.
Alkaloid is mainly based on matrine, Oxymatyine, Sophocarpidin in kuh-seng and the Herba Sophorae alopecuroidis, and after testing, three's content accounts for more than 95% of sophocarpidine.The separation of high purity sophocarpidine series product at present is mainly by column chromatography, and there is the problem little in batches, that cost is high in industrial production.The breach of dealing with problems just is shortening and selective oxidation, realizes that by reaction conversion between the different alkaloids is to simplify sepn process.Most of alkaloids and various organic acids be present in the plant materials with the form of salt, if directly use solvent extraction, effect is not satisfactory, so need to pass through certain processing before extraction, makes it to break away from plant materials, is dissolved in the extraction solvent.Patent of invention " technology for preparing matrine from Herba Sophorae alopecuroidis " (ZL96109730.2) is directly extracted Herba Sophorae alopecuroidis by alkali lye, pass through extractions such as benzene,toluene,xylene, ethylene dichloride, trichloromethane again, the nickel shortening, centrifugal, distillation, recrystallization obtains matrine.Though the author has introduced the notion of hydrogenation, but it is not fine to adopt alkali lye directly to extract alkaloidal effect in the production technique, technological process adopts 70-120 ℃ of high temperature simultaneously, destroyed the intravital flavonoid component of plant, make the Oxymatyine generation deoxidation in the plant material simultaneously, be converted into matrine.Patent of invention " a kind of kurarinone and preparation technology thereof " (CN1277202A) with pure matrine by hydrogen peroxide oxidation, concentrate, industrial alcohol dissolving, evaporate to dryness, anhydrous alcohol solution, evaporate to dryness and acetone backflow, suction filtration etc. obtain white kurarinone, though introducing oxidizing process, but pure matrine also is not easy to obtain, and, the process engineering complexity, running cost is higher.Patent of invention " technology for preparing Oxymatyine from Herba Sophorae alopecuroidis " is (CN1148370) by technologies such as extraction, organic solvent extraction, sour water back extraction, alkaline chemical precipitation, shortening, crystallization, hydrogen peroxide oxidation, crystallizing and dryings, obtain Oxymatyine, but Radix Sophorae Flavescentis alkaloid class material all has bigger solubleness in water, alkaline chemical precipitation in the technology, precipitation often is difficult to obtain, even obtain, the yield of Radix Sophorae Flavescentis alkaloid is not high yet; The sour water back extraction also is difficult to the extraction of the alkaloid in the organic solvent fully, and utilizes the toluene recrystallization, and except yield was low, removing the bigger toluene of toxicity fully also was a problem.Patent of invention " a kind of preparation method of axcnic high pure oxymatrine " (CN1687063A) is extracted Radix Sophorae Flavescentis alkaloid with alkaline solution, supercritical co directly extracts from alkaline solution and obtains sophocarpidine then, hydrogenation, oxidation, crystallization, obtain product, but facts have proved that supercritical co is very limited to the solubleness of Radix Sophorae Flavescentis alkaloid, and Radix Sophorae Flavescentis alkaloid all has bigger solubleness in the aqueous solution, so the product yield that this method obtains is low, and introducing supercritical technology, technology cost height, output is restricted.
