title: Anguivine and isoanguivine, steroid alkaloid glycosides from Solanum anguivi.
abstract: In addition to solamargine, two new steroid alkaloid glycosides, anguivine and isoanguivine, have been isolated from the roots of Solanum anguivi, the structures of which have been elucidated as (25R)-3 beta-[O-alpha-L-rhamnopyranosyl-(1-->2)-O-[beta-D- xylopyranosyl-(1-->3)]-beta-D-glucopyranosyloxy]-22 alpha N-spirosol-5-ene and (25R)-3 beta-[O-alpha-L-rhamnopyranosyl-(1-->2)-O-[beta-D-xylopyranosyl- (1-->3)-beta-D-galactopyranosyloxy]-22 alpha N-spirosol-5-ene.
