A New Lignan Glycoside from Curculigo capitulata

A new lignan glycoside,4,4′-dimethoxy-3′-hydroxy-7,9′∶7′,9-diepoxylignan-3-O-β-D-glucopyranoside (1),was isolated from the rhizomes of Curculigo capitulata,along with eight known compounds (2-9).Their structures were elucidated by spectroscopic and chemical methods and by comparison of their spectral data (MS,()~1H and ()~(13)C) with those reported in the literature.Compounds 2-7 have been obtained from this plant for the first time.
