The constituents of the leaves, stems and underground parts of Trachycarpus fortunei (HOOK.) H.Wendl. (Palmae) have been investigated.Glucoluteolin (3), luteolin 7-O-rutinoside (=scolymoside, 4) and methyl proto-Pb (6) from the leaves, dioscin (1), Pb (2), methyl protodioscin (5) and methyl proto-Pb (6) from the stems, and dioscin (1) and methyl proto-Pb (6) from the underground parts were isolated and identified.This is the first report of the isolation of steroidal saponins from Palmae plants and these results are interesting from the standpoint of chemotaxonomy. keywords - Trachycarpus fortunei; Palmae; steroidal saponin; furostanol oligoside; diosgenin; proto-diosgenin; flavone glycoside; luteolin; glucoluteolin; scolymoside

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-2)>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).
