Özet: A new sesquiterpene, schisandrathera E (1) and seven dibenzocyclooctadiene lignans as schisantherin D (2), schisantherin B (3), tigloylgomisin P (4), schisphenin E (5), angeloylgomisin H (6), (+)-deoxyschizandrin (7), and (+)-gomisin K3 (8) were isolated from the leaves of Schisandra sphenanthera Rehder & E.H.Wilson. Their structures were elucidated by spectroscopic and mass spectrometric analyses, including 1D-, 2D-NMR, HR-ESI-MS and ECD spectra. Compound 1 displayed moderate cytotoxicity against both PC3 and MCF4 cell lines in MTT assay with IC50 values of 22.60 and 7.80 µM, respectively.
