    Abstract:
    Dulcisenes C-E, undescribed polyoxygenated cyclohexenes and twenty-one known compounds were isolated from the dichloromethane extract of the leaves of Uvaria dulcis Dunal. The structures of these undescribed compounds were determined by spectroscopic data analyses, including 1D and 2D NMR, IR, and MS techniques; their absolute configurations were analyzed by NOESY and ECD spectra. Cytotoxicity of sixteen more abundant isolates was evaluated. Cherrevenone and 2',3'-dihydroxy-4',6'-dimethoxychalcone exhibited cytotoxic activity against some cancer cell lines with IC50 values in the range of 3.3-11.8 μM.
