Seven steroidal saponins were isolated for the first time fiom the green berries of Solanum unguiculatum. Their structures were determined by spectroscopic analysis as well as hydrolysis of the glycosides into the corresponding sapogenins, diosgenin, chlorogenin, diosgenin-3-O-β-D-galactopyranoside, diosgenin-3-O-β-D-glucopyranosyl-(1 → 4)-β-D-galactopyranoside, 3β-hydroxyl-(25R) 5α-spirostan-6-one (laxogenin) 3-O-α-L-rhamnopyranosyl-(1 → 2)-β-D-glucopyranoside, isonarthogenin-3-O-α-L-rhamnopyranosyl-(1 → 2)-O-[α-L-rhamnopyranosyl-( 1 → 4)-β-D-glucopyranoside and 25(S) spirost-5-en-3β, 17α, 27 triol-3-O-[α-L-rhamnopyranosyl-(1 → 2)] [α-L-rhamnopyranosyl-(1 → 4)]-β-D-glucopyranoside.Keywords
