Abstract
- In addition to solamargine, isoanguivine and solasonine, two new steroid alkaloid glycosides, xylosylsolamargine and xylosyl-beta-solamarine, have been isolated from the aerial parts of Solanum coccineum, the structures of which have been elucidated as (25R)-3 beta-[O-beta-D-xylopyranosyl-(1-->2)-O-alpha-L-rhamnopyranosyl- (1-->4)-O-[alpha-L-rhamnopyranosyl-(1-->2)]-beta-D-glucopyranosyloxy+ ++]-22 alpha N-spirosol-5-ene and (25S)-3 beta-[O-beta-D-xylopyranosyl-(1-->2)-O-alpha-L-rhamnopyranosyl- (1-->4)-O-[alpha-L-rhamnopyranosyl-(1-->2)]-beta-D-glucopyranosyloxy+ ++]-22 beta N-spirosol-5-ene.
