Both cytotoxic and apoptotic properties of the stem bark extract of Sandoricum koetjape were investigated in vitro. 2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium- 5-carboxanilide (XTT) cell proliferation assay was used to study the cytotoxic properties on three breast cancer cell lines and one normal cell line; MCF-7, MDA-MB-231, T47D and MCF-10A, respectively. Caspase Glo 3/7 assay was used to study the apoptotic activity on MCF-7 as a model cell line. The n-hexane extract showed a dose dependent growth inhibition of all tested cell lines with IC50 values between 44 and 48 μg mL-1. At 100 μg mL-1, the extract induced apoptotic cell death of MCF-7 by inducing activity of the effector caspases 3 and 7. These results indicated that n-hexane extract of S. koetjape has cytotoxic and apoptotic properties on breast cancer cell lines making it a good candidate for further studies.
