Cytotoxicity assay for methanol and aqueous extracts of Jatropha curcas MDCK cells were left untreated (negative control) and treated with the different concentration (2.5, 5, 25, 50 and 100 mg/mL) of both extracts (100 μL/well) and incubated for 18 h at 37 °C. The cell viability was measured using trypan blue dye exclusion assay
