Schisandra sphenanthera Rehder & E.H. Wilson, Schisandraceae, is well known as a type of traditional medicine for the treatment of hepatitis, diarrhea and insomnia in Asia. It was also reported to have antiviral and anti-HIV activities. Using various chromatographic resins and isolation techniques, a new lignan (1), erythro-4-(3,4-dimethoxyphenyl)-4-hydroxy-3-methylbutan-2yl-3,4-dimethoxybenzoate, along with fifteen known compounds, were isolated from fruits of S. sphenanthera. The structures of the compounds were identified by extensive spectroscopic and spectrometric methods including 1D and 2D NMR and MS data. All the isolated compounds were evaluated for their cytotoxicity activity against Hela, HepG2 and HCT-116 cells. Among them, compound schisanlactone C showed significant cytotoxicity activity.
