A new lignan glycoside, 5-(3aEuro(3),4aEuro(3)-dimethoxy-phenyl)-3-hydroxy-3-(4'-hydroxy-3'-methoxybenzyl)-4-hydroxymethyl-dihydrofuran-2-one 4'-O-alpha-l-rhamnopyranoside (1), with seven known compounds, compound 2, koaburside, icariside E(4), cleomiscosin C, cleomiscosin D, scopoletin, and 5'-demethylaquillochin, were isolated from the EtOH extract of the wood of Acer saccharum (Aceraceae). Their structures were determined by 1D and 2D nuclear magnetic resonance (NMR) and mass spectroscopy analysis. All of the isolated compounds, 1-8, were tested for their antioxidant activity in superoxide dismutase (SOD)-like assay.
