Abstract

The four new lariciresinol‐based lignan glycosides, (−)‐lariciresinol 4′‐(6″‐O‐feruloyl‐β‐D‐glucopyranoside) (1), (−)‐lariciresinol 4′‐(4″,6″‐di‐O‐feruloyl‐β‐D‐glucopyranoside) (2), 5,5′‐dimethoxylariciresinol 4′‐(4″,6″‐di‐O‐feruloyl)‐β‐D‐glucopyranoside) (3), and 4‐O‐[α‐(1,2‐dihydroxyethyl)syringyl]‐5,5′‐dimethoxylariciresinol 4′‐(4″,6″‐di‐O‐feruloyl‐β‐D‐glucopyranoside) (4), together with two known ones, lariciresinol 4′‐β‐D‐glucopyranoside) (5) and tortoside B (6), were isolated from the BuOH extract of Rhus javanica var. roxburghiana roots, and their structures were established by means of various spectroscopic techniques.
