Figure 7: Effect of HFMOL on (a) caspase 3 activity and (b) ROS generation in HT-29 cells. The colon cancer cells, HT-29 were treated with HFMOL at different concentrations 100 and 200 mg/mL for 24 h. After the specific time point, the level of ROS and activity caspase 3 were determined according to the specific methods as described in method section. The results in the graph represent the means ± SD of triplicate individual experiments. *P < 0.05 denotes significant difference from untreated group (control). HFMOL: Hexane fraction of Moringa oleifera leaves; SD: Standard deviation; ROS: Reactive oxygen species
