Steroidal alkaloid glycosides from Solanum suaveolens.
In addition to khasianine, solamargine, xylosylsolamargine and solasonine, three steroidal alkaloid glycosides, solasuaveoline, dihydrosolasuaveoline and isosolasuaveoline, have been isolated from aerial parts of Solanum suaveolens. The structures have been assigned by NMR investigations as (25R)-3 beta-{O-beta-D-glucopyranosyl-(1-->2)-O-beta-D- glucopyranosyl-(1-->4)-[O-alpha-L-rhamnopyranosyl-(1-->2)]-beta-D- galactopyranosyloxy}-22 alpha N-spirosol-5-ene, (25R)-3 beta-{O-beta-D-glucopyranosyl-(1-->2)-O- beta-D-glucopyranosyl-(1-->4)-[O-alpha-L-rhamnopyranosyl-(1-->2)]-beta-D - galactopyranosyloxy}-5 alpha, 22 alpha N-spirosolane and (25R)-3 beta-{O-beta-D-glucopyranosyl-(1-->6)-O- beta-D-glucopyranosyl-(1-->3)-[O-alpha-L-rhamnopyranosyl-(1-->2)]-beta-D - galactopyranosyloxy}-22 alpha N-spirosol-5-ene, respectively.
