Popis:	Two steroid glycosides of the spirostan series — nicotianosides A and B — and one glycoside of the furostan series — nicotianoside E — have been isolated from the seeds ofNicotiana tabacum L. Nicotianoside A is (25S)-5α-spirostan-3β-ol 3-O-β-D-glucopyranoside, nicotianoside B is (25S)-5β-spirostan-3β-ol 3-O-[O-α-L-rhamnopyranosyl-(1→2)-gb-D-glucopyranoside], and nicotianoside E is (25S)-5α-furostan-3β,22α,26-triol 26-O-β-glucopyranoside 3-O-[O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside].
