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.
