Abstract
A new lignan glycoside, 6-acetyl-1-[1,3-(4,4′-dihydroxy-3,3′-dimethoxy-β-truxinyl)-β-d-fructofuranosyl]-α-d-glucopyranoside (1), named impecyloside, was isolated from the rhizomes of Imperata cylindrica. The structure of the compound was determined by spectroscopic data including FABMS, UV, IR, 1H NMR and 13C NMR (DEPT) and 2D NMR (COSY, HSQC, HMBC).
