Abstract

Besides solasonine, three new glycosides, namely, 3-O-α-L-rhamnopyranosyl-(1→3)-solasodine, 3-O-α-L-rhamnopyranosyl-(1→2)-α-L-rhamnopyranosyl-(1→4)-β-D-galactopyranosyl solasodine, and 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-galactopyranosyl solasodine, were isolated fromSolanum unguiculatum (A.) Rich. Their structures were determined on the basis of chemical and spectral methods.
