The cells were treated with indicated concentrations of (a) methanol and (b) aqueous extracts of S. ferruginea for indicated time intervals. The results are expressed as the percentage of the negative control. Cytotoxic activity of the extracts was compared to the reference drug, tamoxifen (Fig 3C). Cell viability was measured by MTT assay. Data are means ± SD of triplicate in three independent experiments. All data showed statistically significant difference from untreated control (one-way ANOVA, P < 0.05).
