Abstract
Seven steroidal glycosides, tentatively named glycosides Ls-1, Ls-2 (1), Ls-3 (2), Ls-4 (3), Ls-5 (4), Ls-6 (5) and Ls-7 (6) were isolated from the subterranean part of Liriope spicata (THUMB.) LOUR. var. prolifera Y. J. MA (Liliaceae) and three steroidal glycosides, tentatively named glycosides Lm-1, Lm-2 (7), Lm-3 (8) were isoalted from L. muscari (DECN.) BAILEY (Liliaceae). Glycosides Ls-1 and Lm-1 were identified as so-called β-sitosterol β-D-glucopyranoside. The structures of eight glycosides (1-8) were established as (25S)-ruscogenin 1-O-β-D-fucopyranosido-3-O-α-L-rhamnopyranoside (1)(=glycoside B from L. platyphylla WANG. et TANG.), (25S)-ruscogenin 1-O-β-D-xylopyranosido-3-O-α-L-rhamnopyranoside (2), (25S)-ruscogenin 1-O-α-L-rhamnopyranosyl(1→2)-β-D-xylopyranoside (3), (25S)-ruscogenin 1-O-[(2-O-acetyl)-α-L-rhamnopyranosyl(1→2)][β-D-xylopyranosyl(1→3)]-β-D-fucopyranoside (4), (25S)-ruscogenin 1-O-[(3-O-acetyl)-α-L-rhamnopyranosyl(1→2)][β-D-xylopyranosyl(1→3)]-β-D-fucopyranoside (5), yamogenin 3-O-[α-L-rhamnopyranosyl(1→2)][β-D-xylopyranosyl(1→3)]-β-D-glucopyranoside (6), ruscogenin 1-O-β-D-glucopyranosyl(1→2)-β-D-fucopyranoside (7) and ruscogenin 1-O-[β-D-glucopyranosyl(1→2)][β-D-xylopyranosyl(1→3)]-β-D-fucopyranoside (8), respectively.
