Abstract:
1. A method for the separation of a rhamnose-glucose-galactose triglycoalkaloid and a rhamnose-rhamnose-glucose triglycoalkaloid from a mixture containing both the rhamnose-glucose-galactose triglycoalkaloid and the rhamnose-rhamnose-glucose triglycoalkaloid, the method comprising the steps of: Combining the mixture with a portion of alcoholic solvent; Causing or allowing a substantial portion of the rhamnose-rhamnose-glucose triglycoalkaloid to dissolve, thereby generating an alcoholic solution substantially of the rhamnose-rhamnose-glucose triglycoalkaloid, and a solid substantially comprising the rhamnose-glucose-galactose triglycoalkaloid; and Separating the solid substantially comprising the rhamnose-glucose-galactose triglycoalkaloid from the solution substantially of the rhamnose-rhamnose-glucose triglycoalkaloid.
