AbstractTwo limonoids were isolated from the methanol extract of Khaya senegalensis (Meliaceae), and their structures were identified as 3α,7α‐dideacetylkhivorin (1) and 1‐O‐acetylkhayanolide B (2) on the basis of MS and NMR spectral data. Complete assignments of 1H and 13C chemical shifts for compounds 1 and 2 were achieved by means of 1D and 2D NMR including DEPT, 1H‐1H COSY, HMQC, HMBC experiments. Compound 1 showed significant growth inhibitory activities against MCF‐7, SiHa and Caco‐2 cells with IC50 values in the range of 0.07–0.14 µm (35–69 ppm) while compound 2 did not.
