(-)-Lyoniresinol has antioxidant activity.

Eight new lignan glucosides, tarennanosides A-H ( 1 - 8 , resp.), were isolated from the whole plant of Tarenna attenuata , together with three known compounds, fernandoside, (-)-Lyoniresinol, and (-) - isolariciresinol. The planar structures of new compounds were elucidated mainly by analysis of physical and spectroscopic data, and the absolute configurations were determined by acid hydrolysis as well as CD spectroscopy. Compounds 1 and 2 exhibited potent antioxidant activities against H2O2-induced impairment in PC12 cells.
