Comparative cytotoxic effect of different solvent extracts of honeydew melon on HeLa cell lines after 24 h of incubation. Data is expressed as the mean ± SD (each treatment, n = 3). ∗∗∗∗ indicates p < 0.0001 in comparison with control/untreated cells by one-way ANOVA followed by Dunnett's test for multiple comparisons.
