Further investigation of the stems of Schisandra bicolor led to the isolation of a new dibenzylbutane lignan, named schibicolignan A (1), as well as five known compounds, namely bis[dibenzylbutane] (2), machilin A (3), macelignan (4), saururenin (5) and sphenanlignan (6). The structure of the new lignan was elucidated on the basis of extensive spectroscopic analysis. Antioxidant activity of 1–6 was also evaluated.
