EtOAc extract induced apoptosis in SW480, HCT 116 and HT-29 cell lines. Each cell line was treated with its related IC50 value for 48 h, and cell apoptosis was evaluated by Annexin V/PI staining (A). Obtained results were quantitated as a chart and data are mean ± SEM (n = 3). *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001; ns, non-significant compared with control groups (B)
