Lignan glucosides from Acanthus ilicifolius

From the aerial part of Acanthus ilicifolius, two lignan glucosides. (+)-lyoniresinol 3a-[2-(3,5-dimethoxy-4-hydroxy)-benzoyl]-O-β-glucopyranoside, and dihydroxymethyl-bis(3,5-dimethoxy-4-hydroxyphenyl) tetrahydrofuran-9(or 9′)-O-β-glucopyranoside have been isolated, together with eight known compounds. The structural elucidations were based on the analyses of physical and spectroscopic data. © 2001 Elsevier Science Ltd.
