The bulbs of Lilium dauricum yielded 11 compounds, including six new steroidal glycosides. The structures have been determined by spectral analysis and hydrolysis to be (25R,26R)-26-methoxyspirost-5-en-3-beta-ol 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-O-[alpha-L-arabinopyranosyl-(1 --> 3)]-beta-D-glucopyranoside, (25R,26R)-26-methoxyspirost-5-en-3-beta-ol 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-O-[beta-D-glucopyranosyl-(1 --> 4)]-beta-D-glucopyranoside, (25R)-spirost-5-en-3-beta-ol (diosgenin) 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-O-[alpha-L-arabinopyranosyl-(1 --> 3)]-beta-D-glucopyranoside, (25R)-3-beta,17-alpha-dihydroxy-5-alpha-spirostan-6-one 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-glucopyranoside, (25R)-3-beta,17-alpha-dihydroxy-5-alpha-spirostan-6-one 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-O-[alpha-L-arabinopyranosyl-(1 --> 3)]-beta-D-glucopyranoside and (20R,22R)-3-beta,20,22-trihydroxy-5-alpha-cholestan-6-one (tenuifoliol) 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-glucopyranoside. The absolute configurations of C-20 and C-22 of tenuifoliol were further confirmed by detailed analysis of the NOE difference spectrum of the corresponding isopropylidene derivative. Several known compounds were also isolated and identified.
