One new steroidal glycoside, 26-O-β-D-glucopyranosyl-(25R)-furost-3β, 22ξ, 26-triol-5-ene-3-α-L-rhamnopyranosyl-(1-2)-[3-O-(3-O-acetyl)-α-L-rhamnopyranosyl-(1-4)]-β-D-glucopyranoside (1) were isolated from the fresh fruits of the edible plant Solanum spirale Roxb., together with two known ones, 26-0-β-D-glucopyranosyl-(25R)-furost-22ξ-methoxyl-3β, 26-diol-5-ene-3-0-α-L-rhamnopyranosyl-(1-2)-β-D-glucopyranoside (2) and 26-O-β-D-glueopy-ranosyl-(25R)-furest-3β, 22ξ, 26-triol-5-ene-3-0-α-L-rhamnopyranosyl-(1-2)-[α-L-rhamnopyranesyl-(1-4)]-β-D-glucopyraneside (protedioscin) (3). Their structures were elucidated by spectroscopic methods, especially 2D NMR. The known compounds 2-3 were isolated from the title plant for the first time.
