Two new cyclolignan glycosides from Acanthus ilicifolius

Abstract

Two new cyclolignan glycosides, (+)-lyoniresinol 3a-O-α-D- galactopyranosyl-(1 → 6)-β-D-glucopyranoside (1) and (+)-lyoniresinol 2a-O-α-D-galactopyranosyl-3a-O-β-D-glucopyranoside (2) were isolated from the aerial parts of Acanthus ilicifolius. Their structure elucidation is based on the analyses of spectroscopic data.
