Cell apoptosis representation of human cancer cells (HT-29) under the influence of absolute and 80% methanolic extracts of Rumex crispus roots. (A): Phase contrast microscopic examination of cell apoptosis of human cancer cells (HT-29); 1) Control; 2) 80% methanolic extract; 3) Absolute methanolic extract. (B): Cell apoptosis % of human cancer cells (HT-29) at different concentration of root extracts of Rumex crispus in culture for 48 h. Cell viability was measured using an MTT assay. Data represent the mean ± SD of three independent experiments.
