Effects of Gynura procumbens leaves extract (GPE) on the caspase 3/7 activation in CHMp‐13a (a) and CHMp‐5b (b) cells were estimated using luminescence analysis. Cells were treated with three different concentrations (0, 80, and 160 μg/ml) of GPE at 0, 6, 12, and 28 h. Caspase 3/7 activity was expressed as percentage of control. Each data point indicates the mean of four separate experiments ± SD. Statistical differences were analyzed using Kruskal Wallis followed by Dunn's multiple comparisons post hoc tests. Significant differences from the control are indicated: ^∗ p < 0.05; ^∗∗ p < 0.01
