Description
Изобретение относитс к производству лекарственных препаратов.The invention relates to the manufacture of drugs.
Известен способ получени раунатина путем экстрагировани растительного сырь - коры и корней раувольфии водным раствором уксусной кислоты, подш,елачивани экстракта , обработки органическим растворителем , упаривани и высушивани .A known method of obtaining roundin by extracting plant raw materials - bark and rauwolfia roots with an aqueous solution of acetic acid, honey, extracting the extract, treating with an organic solvent, evaporation and drying.
В соответствии с предлагаемым способом экстракт после подщелачивани фильтруют и извлекают алкалоиды известными приемами из осадка и раствора. Это позвол ет упростить технологию производства и увеличить выход раунатина.In accordance with the proposed method, the extract after alkalization is filtered and the alkaloids are extracted by known methods from the precipitate and solution. This allows to simplify the production technology and increase the yield of roundin.
Пример. 45 кг коры раувольфии, содержащей 5% суммы алкалоидов, экстрагируют 10%-ным водным раствором уксусной кислоты методом противотока в батарее экстракторов . Получают 300 л экстракта с содержанием 0,675% суммы алкалоидов. К этому экстракту добавл ют при длительном перемешивании 75 л водного раствора аммиака и центрифугируют . Полученный осадок (1299 г) сушат и раствор ют в 8-10 л изопропилового спирта при лодогреве до 40-50°С. Из спиртового раствора извлекают алкалоиды экстракцией хлороформом (9 л и 2-3 порции по6л). Из фильтрата (после центрифугировани ) алкалоиды извлекают жидкостной экстракцией или адсорбционным методом. Полученные в итоге хлороформенные растворы смешивают и выдел ют раунатин известными приемами. Выход-1550-1600 г раунатина.Example. 45 kg of rauwolfia bark, containing 5% of the amount of alkaloids, are extracted with a 10% aqueous solution of acetic acid by the countercurrent method in an extractor battery. Get 300 liters of extract containing 0.675% of the amount of alkaloids. To this extract, 75 liters of aqueous ammonia solution are added with prolonged stirring and centrifuged. The resulting precipitate (1299 g) is dried and dissolved in 8-10 liters of isopropyl alcohol with water heating up to 40-50 ° C. Alkaloids are extracted from the alcoholic solution by extraction with chloroform (9 l and 2-3 portions of 6 liters). From the filtrate (after centrifugation), the alkaloids are extracted by liquid extraction or by the adsorption method. The resulting chloroform solutions are mixed and the raunatin is isolated by known techniques. The yield is 1550-1600 g round.
Предмет изобретени Subject invention
Способ получени раунатина путем экстрагировани коры и корней раувольфии водным раствором уксусной кислоты, подщелачивавани экстракта, обработки органическим растворителем, упаривани и высушивани , отличающийс тем, что, с целью упрощени технологии производства и повышени выхода целевого продукта, экстракт после подщелачивани фильтруют и извлекают алкалоиды известным образом из осадка и раствора.The method of obtaining roundin by extracting bark and rauwolfia roots with an aqueous solution of acetic acid, alkalizing the extract, treating with an organic solvent, evaporation and drying, characterized in that, in order to simplify the production technology and increase the yield of the target product, the extract after alkalizing is filtered and the alkaloids are extracted in a known manner from sediment and solution.
