Figure 4: (a) Flow cytometry analysis to evaluate apoptosis induction in HT-29 and HCT-116 cells treated with 100 µg/ml of tannins fraction of black date and powdery date and tannic acid or 100 nM camptothecin control for 24 h. Percentage of apoptotic (b) HT-29 and (c) HCT-116 cells in various treatments were compared. Results were expressed as mean ± standard error mean of three independent experiments (n = 3). Bars with different letters represent significant differences (P < 0.05)
