Jatropha curcas L. commonly known as physic nut or purging nut, is a drought resistant shrub belonging to the family Euphorbiaceae, was analyzed for its accumulation capacity of heavy metals such as lead (Pb), cadmium (Cd) and chromium (Cr). Bioassay was conducted by raising the plant by vegetative propagating the stem cutting in varying concentration of respective heavy metals. The metal concentration in the bioparts of experimental plant revealed that the treated plants accumulated enormous quantity of lead, cadmium and chromium as compared to control plant. The effect of heavy metal stress on antioxidant activity in of J. curcas was investigated. The activity of enzymatic antioxidant such as superoxide dismutase (
