Modulatory effect of standardized extract of Withania somnifera (WS, 0.01 and 0.05 %, 7 days) on ROT (500 μM, 7 days) -induced mortality expressed as percent mortality (a) and negative geotaxis (b) among adult male Drosophila melanogaster; This was assessed in a co-exposure paradigm in which flies were exposed to ROT in a WS-enriched medium for 7 days; Values are mean ± SE (n = 50 flies per replicate, three such replication used for assay); Data was analyzed by one way ANOVA followed by post hoc ‘Tukey’ test (*p < 0.05)
