【摘要】 [Objective]To research on the extraction,isolation and purification technologies of cyasterone from RADIX CYATHULAE.[Methods]Reflux extraction for crude RADIX CYATHULAE was carried out.Orthogonal test and macroporous adsorption resin isolation test were used to select the optimal technology.And slica column chromatography was adopted for purification.[Results]The optimal extraction technology for RADIX CYATHULAE was reflux extraction by 70%ethanol for 2 times.The optimal isolation technology for cyasterone by macroporous resin was as follows:50%ethanol at the elution rate of 0.8 BV/min.During the purification by slica column chromatography,chloroform-95%ethanol(10∶1,V/V)was used as eluent.After recrystallization,cyasterone crystal was obtained.[Conclusions]This method was simple,economical and practical,and was suitable for small-scale production.
