Abstract:

A new lignan glycoside, named (7S,8R,8′R)-(−)-lariciresinol-9-O-α-L-rhamnopyranosyl (1→2) β-D-glucopyranoside (1),was isolated from the ethanol extract of Pilea cavaleriei Levl subsp. cavaleriei, together with 17 known lignans (2−18). The structures of these compounds were elucidated by extensive spectroscopic analysis, including 1D NMR, 2D NMR and HR-ESI-MS. All the compounds were obtained from the genus Pilea for the first time.

Key words: Pilea cavaleriei Levl subsp. cavaleriei, Urticaceae, Lignan glycosides, Lignans
