Seven compounds were isolated from the roots of Eurycoma longifolia, and characterized by comprehensive analysis of 1D and 2D NMR experiments along with single crystal X-ray diffraction. Among them, four new quassinoids were identified and three of them were diastereomers for each other. Compounds 1-7 were evaluated for cytotoxicities against HT-29, MCF-7, LOVO, BGC-823, MGC-803, HepG2, HeLa, and A549 cancer cell lines. Compounds 2 and 5 exhibited the lowest IC50 values of 24.9 mu M, 11.8 mu M, and 44.1 mu M, 14.1 mu M towards MCF-7, MGC-803 cancer cell lines, respectively, while compound 6 exhibited moderate cytotoxicity towards all the selected cancer cell lines.
