Two new dibenzocyclooctadiene lignans, benzoylgomisin Q (1) and benzoylgomisin P (2) were isolated from the fruits of Schisandra sphenanthera REHD. et WILS. (Schisandraceae) together with angeloylgomisin P (8), tigloylgomisin P (9), and (+)-gomisin K3 (10) which were the components of Schisandra chinensis BAILL. The structures of 1 and 2 were determined by spectral studies and chemical correlation with schisantherin A (3) and 8, respectively.
