Antiproliferative effects of the extracts of (A) O. stamineus, (B) G. procumbens and (C) F. deltoidea on three human cancer cell lines at 24 h and 48 h. Cells were treated with various concentrations (50, 125, 250, 500, 750, 1000 µg/mL) of methanol, ethyl acetate, chloroform and butanol extracts. Cell proliferation was measured at 24 h and 48 h by MTT assay. The data were expressed as mean ± SD deviation values obtained from three independent determinations. *, P < 0.05 versus controls.
