Antioxidant Activity of Jatropha curcas and Jatropha gossypifolia by DPPH Method

Heart disease, cancer, diabetes, ischemia, and aging are diseases caused due to oxidative stress condition because the accumulation of free radicals. The negative effect of free radicals in the body can be resisted or scavenged by antioxidants. Jatropa sp. belongs to the family Euphorbiaceae contained alkaloids, tannins, flavonoids, steroid, saponins, and phenol compounds.This study has been detemined for an antioxidant activity both of J.curcas and J.gossypifolia. Extraction was performed by maceration methode. The ethanol extracts were vaporated using rotavapor. The antioxidant capacities were tested using DPPH assay. The results showed that Jatropha curcas had activity as an antioxidant with a very active intensity can be found in the parts of stem bark. Whereas in the J.gossypifolia plants that had an antioxidant activity with a very active intensity were the leaves and stem bark
