The petroleum ether, chloroform and methanol leaf extracts showed strong in vitro antiproliferative activities (IC50 : 6.5 - 25.4 μg/ml) for MCF-7 (human hormone-dependent breast cancer cell line) and (IC50 : 19.3 - 26.8 μg/ml) for MDA-MB-231 (human hormone non-dependent breast cancer cell line). The IC50 value against HL-60 (human leukemia cell line) between 6.91 and 9.98 μg/ml for chloroform, petroleum ether and methanol extracts. Non-cytotoxic activity towards the non-tumour 3T3 mouse fibroblast indicated that the extracts exhibited selective mode of inhibition between tumor and non-tumor cells. The findings of antioxidative and antiproliferative activities of the plant extracts in vitro suggested that this species does contain antioxidant and cytotoxic compounds.
