title: Steroidal alkaloid glycosides from Solanum uporo.
abstract: In addition to solamargine, anguivine and isoanguivine, two new steroidal alkaloid glycosides, (23S)-23-hydroxyanguivine and (23S)-23-hydroxyisoanguivine, have been isolated from roots of Solanum uporo, the structures of which have been assigned by comparison with literature data as (23S,25R)-3 beta-[O-alpha-L-rhamnopyranosyl-(1-->2)-O- [beta-D-xylopyranosyl-(1-->3)]-beta-D-glucopyranosyloxy]-22 alpha N-spirosol-5-en-23-ol and (23S,25R)-3 beta-[O-alpha-L-rhamnopyranosyl-(1-->2)-O-[beta-D- xylopyranosyl-(1-->3)]-beta-D-galactopyranosyloxy]-22 alpha N-spirosol-5-en-23-ol.
