| titleOfInvention | Method of androst-4-en-3,17-dione isolation |
| abstract | FIELD: chemical technology of steroids. SUBSTANCE: cultural fluid prepared by microbiological oxidation of sterol with culture Mycobacterium NRRL B-3805 is filtered. Residue on the filter is extracted with a mixture of organic solvent and water at their ratio (0.7-4):1. Mixture is filtered, filtrates are combined and evaporated. Residue prepared is treated with petroleum ether. The end product is prepared in the form of crystalline white powder. The yield is 74.5-91% of androst-4-en-3,17-dione in cultural fluid. EFFECT: simplified method. |
