Abstract

Five new compounds including two tetrahydrofuran-type lignans, beilschmin A and beilschmin B, a dihydrofuran-type lignan, beilschmin C, and two 1-phenylbutyl benzoates, tsangin A and tsangin B, together with thirteen known compounds have been isolated from the stem of Beilschmiedia tsangii. The structures of these new compounds were determined through spectral analyses. Among the isolates, beilschmin A (1), beilschmin B (2), beilschmin C (3), tsangin A (4), tsangin B (5), 2,6,11-trimethyldodeca-2,6,10-triene (14), α-tocopherylquinone (17), and α-tocospiro B (18) were cytotoxic (IC50 values < 4 μg/mL) in P-388 and/or HT-29 cell lines in vitro.
