Results are given which confirm the structure of the furostanol glycoside from tomato seeds forming wastes of the preserving industry.From a butanolic extract of the seeds of Lycopersicum esculentum Mill. we have isolated the furostanol glycoside tomatoside A (I) the structure of which has been established as 25(S)-5α-furostan-3β,22α,26-triol 26-O-β-D-glucopyranoside 3-O2)-O-β-D-glucopyranosyl-(1->4)-β-D-galactopyranoside>.At the same time, by enzymatic and chemical transformations three new spirostanol glycosides of neotigogenin have been obtained: tomatoside B (III), which is 25(S)-5α-spirostan-3β-ol 3-O-2)-β-D-galactopyranoside>, 25(S)-5α-spirostan-3β-ol 3-O-4)-β-D-galactopyranoside> (V), and 25(S)-5α-spirostan-3β-ol 3-O-β-D-galactopyranoside (IV).
