Separation of hecogenin-tigogenin mixtures
-
, (2008/06/13)
A process for separating hecogenin-tigogenin mixtures which involves acetylating the mixed genins, then solvent recrystallization separation of the mixed genin acetates, crystallizing out hecogenin acetate from a non-polar solvent, tigogenin acetate from a polar solvent. A sequential sequence is contemplated to first recover the predominant genin, then the less-predominant genin. Preferred source materials are crude 5-25% sapogenin content acid hydrolyzates of Agave leaf juice. Specifically preferred is the acid hydrolyzate from fresh Agave leaf juice obtained prior to decortication.
