Abstract: In accordance with the present invention there is provided a method for the separation of a triglycoalkaloid in which the triglycoside portion comprises ?-L-rhamnopyranosyl-(1?2gal)-O-?-D-glucopyranosyl-(1?3gal)-?-D-galactopyranose (or 6-deoxy-?-L-mannopyranosyl-(1?2)-O-[?-D-glucopyranosyl-(1?3)]-?-D-galactopyranoside) (‘an rhamnose-glucose-galactose triglycoalkaloid’) from a triglycoalkaloid in which the triglycoside portion is ?-L-rhamnopyranosyl-(1?2glu)-O-?-L-rhamnopyranosyl-(1?4glu)-?-D-glucopyranose (‘a rhamnose-rhamnose-glucose triglycoalkaloid’) in a mixture containing both, 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 com
