Figure 3 Neuroprotective effect of H. rhamnoides on H2O2
induced cell cytotoxicity: PI staining assay. Note – Values
represented as mean ±SD. ANOVA followed by dunnett’s test
was carried out to determine the level of significance. Comparison
was made between the treated and H2O2 control group. Toxicity
results of IMR32 cell line induced with 250 lM of H2O2 and pre
incubated with different concentrations of H. rhamnoides extract.
