The cytotoxicity effect of ethanol, methanol, and aqueous P. glabra crude leaf extracts against the MCF-7 cell lines after three different time points of treatment where A 24 h, B 48 h, and C 72 h. The error bars represent the standard error of the mean (SEM). Data are expressed as a mean percentage of viable cells ± SEM of at least three replicates in three independent tests; The asterisk symbols (*), (**), and hash symbol (#) indicate p < 0.05, **p < 0.01 and #p < 0.001, respectively. The differences were determined by two-way ANOVA and Tukey’s post hoc test
