  1. Results were expressed as Mean ± SEM (n = 3) and analysed using one-way ANOVA followed by Tukey’s post hoc test of significance [where different alphabets denote significant difference (p <0.05)]. Statistical comparison between the mean % viability of each extract and its negative control was performed using one-way ANOVA followed by Dunnett’s post hoc test of significance wherein *p <0.05 and **p <0.01 were considered to be statistically significant and very statistically significant compared to negative control. A.carnosus extracts were tested at concentrations of 200, 100, 50, 25 μg/ml (they were not tested at concentrations of 6.25 and 12.5 μg/ml). Paclitaxel was tested at concentrations of 6.25, 12.5, 25 and 50 μg/ml.
