Three new limonoids namely pentandricines B-D (1-3), were isolated from n-hexane extract of the stem bark of Chisocheton pentandrus, along with four known limonoids (4-7). The chemical structures of pentandricines B-D, were fully elucidated based on UV, IR, HR-TOFMS, 1D- and 2D-NMR spectra. Furthermore, compounds 1-7 were evaluated for their cytotoxic activity against MCF-7 breast cancer cells in vitro, with compound 7 (nimonol) showing strongest cytotoxicity activity with an IC50, value of 22.03 +/- 0.026 mu M.
