Abstract

A steroidal sapogenin, e.g. hecogenin, is obtained from plant material containing sapogenin-yielding material, e.g. the waste from decorticated sisal leaves, by a process in which the juice is expressed to separate the sapogenin-yielding material therefrom. Subsequently the juice is subjected to acid hydrolysis, e.g. with sulphuric acid, to provide water-insoluble hecogenin which is recovered from the hydrolysate by collection on an adsorbent substance, such as activated charcoal, and which is extracted with a solvent, e.g. ether, isopropyl ether, ethyl acetate benzene or carbon tetrachloride. The hecogenin is obtained therefrom by fractional crystallization. Specification 702,072 is referred to.
