Three new lignans from the seeds of Saussurea involucrata

Abstract

Three new lignans, arctigenin-4-O-(6″-O-acetyl-β-d-glucoside) (1), arctigenin-4-O-(2″-O-acetyl-β-d-glucoside) (2), and arctigenin-4-O-(3″-O-acetyl-β-d-glucoside) (3), together with two known lignans, were isolated from the seeds of Saussurea involucrata. Their structures were established by spectroscopic methods, mainly 1D and 2D NMR, and mass spectral analysis.
