Eight steroidal glycosides, tentatively named glycosides A (1), B (2), C (3), D (4), E (5), F (6), G (7) and H (8), were isolated from the methanol extract of the subterranean part of Liriope platyphylla WANG et TANG (Liliaceae). The structures of these glycosides were established as ruscogenin 3-O-α-L-rhamnopyranoside (1), 25 (S)-ruscogenin 1-O-β-D-fucopyranosido-3-O-α-L-rhamnopyranoside (2), 25 (S)-ruscogenin 1-O-α-L-rhamnopyranosyl-(1→2)-β-D-fucopyranoside (3), ruscogenin 3-O-β-D-glucopyranosyl (1→3)-α-L-rhamnopyranoside (4), a mixture of 3-O-[α-L-rhamnopyranosyl (1→2)][β-D-xylopyranosyl (1→3)]-β-D-glucopyranosides of diosgenin and yamogenin (=a mixture of ophiopogonin D' and its 25 (S)-isomer, 5), a mixture of 3-O-β-chacotriosides of diosgenin and yamogenin (=a mixture of dioscin and its 25(S)-isomer, 6), ruscogenin 1-sulfate 3-O-α-L-rhamnopyranoside (7), and 26-O-β-D-glucopyranosyl-22-O-methylfurost-5-ene-3β, 26-diol 3-O-β-chacotrioside (=methyl proto-dioscin, 8).
