Abstract
Besides solasonine, three new glycosides, namely, 3-O-alpha-L-rhamnopyranosyl-(1-->3)-solasodine, 3-O-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-rhamnopyranosyl-(1-->4)-beta -D- galactopyranosyl solasodine, and 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-galactopyranosyl solasodine, were isolated from Solanum unguiculatum (A.) Rich. Their structures were determined on the basis of chemical and spectral methods.
