Studies on the Constituents of Palmae Plants. I. The Constituents of Trachycarpus fortunei (HOOK.) H. WENDL. (1)

Hirai, Yasuaki,Sanada, Shuichi,Ida, Yoshiteru,Shoji, Junzo

, p. 295 - 301 (2007/10/02)

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
