mode of steroid сапогенинов of купены smooth

摘要

the invention relates to the pharmaceutical industry and for receiving from the plant material steroid сапогенинов - диосгенина and пенногенина are reliable.accessible and valuable raw materials for drugs, hormones, especially some cortisone for and прегнанов.the objective is achieved bywhat mode of steroid сапогенинов of купены smooth Polygonatum glaberrimumпутем extraction plant material water solution одноатомного алифатического alcoholwith the subsequent гидролизом with a sulfuric acid solution in the organic solvent were inferior by disappearing into a гидролизата and obtaining the target product whichaccording to the invention where extractions were 70% ethanol in a ratio of 1: 6 (raw materials, ethanol) during 24 h four times, after which all the extracts by alcohol and water, before giving up tca.экстрагируют - бутанолом, washed 10% ammonia solution, n - бутанол defend completely, the residue after neutralization and drying экстрагируют петролейным ether with t. the trc.70 100°с when heated, and hot air vent immediately, leave for the day, then separate the leachate and winning the residue, кристаллизуют and receive the пенногенин,from the leachate prevent petroleum ether completely dry the rest of the кристаллизуют and receive the диосгенин.
