Изобретение относитс к способам выделени соединений, полученных микробиологическим путем.This invention relates to methods for isolating microbiologically prepared compounds.
Известен способ выделени стероидов из кзльтуральной жидкости путем экстракции 30-200 об. %-ным избытком хлороформа.There is a method for isolating steroids from an aqueous liquid by extraction of 30-200 vol. % excess chloroform.
С целью повышени степени чистоты целевого продукта в предлагаемом способе стероиды осаждают добавлением 1-2 об. % хлороформа .In order to increase the purity of the target product in the proposed method, steroids are precipitated by adding 1-2 vol. % chloroform.
Способ осуществл ют следующем образом.The method is carried out as follows.
К отфильтрованной от мицели пробе культуральной жидкости, содержащей стероид, добавл ют 1-2 об. % хлороформа, и раствор перемещивают в течение 2 час при охлаждении до 5° С. Выделившийс стероид отфильтровывают , промывают водой и сушат при 60 С.To the sample of culture liquid containing the steroid filtered from the mycelium, 1-2 vol. % chloroform, and the solution is moved for 2 hours while cooling to 5 ° C. The excreted steroid is filtered off, washed with water and dried at 60 C.
Пример. 8 л пробы культуральной жидкости , содержащей 16 г эникортизола, отфильтровывают от мицели и загружают в аппарат с мешалкой. Туда же добавл ют 120 мл (1,5%) хлороформа. Раствор перемешивают в течение 2 час при охлаждении до 5° С. Выделившийс зппкортизол отфильтровывают, промывают водой и сушат при 60° С. Выход сухого эпикортизола 1-1,3 г (89,3%).Example. 8 l of sample culture fluid containing 16 g of enicortisol, filtered from the mycelium and loaded into the apparatus with a stirrer. 120 ml (1.5%) of chloroform was added thereto. The solution is stirred for 2 hours while cooling to 5 ° C. The released sppcortisol is filtered off, washed with water and dried at 60 ° C. The yield of dry epicortisol is 1-1.3 g (89.3%).
