A Comparative Study on Antioxidant and Cytotoxic Potentials of Methanol Extract of Jatropha curcas Seeds and Leaves

Many medicinal plants have been reported to exhibit protective effects against many physiological diseases as a result of their phytochemical components which are effective antioxidants. This study was aimed at comparing the phenolic and flavonoids contents, antioxidant cytotoxic activities methanol extract Jatropha curcas seeds leaves. The cytotoxicity level J. assessed using brine shrimp lethality test (BSLT). activity determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, ferric reducing power (FRAP), nitric oxide activities, 2, 2’-azino-bis-(3 ethyl benzothiazoline-6-sulphonic acid (ABTS) + total capacity. phenols content (TPC) were carried out aluminum chloride Folin-Ciocalteu assay respectively. results showed that leaves significant higher contents than seeds. capacity FRAP also significantly in curcas. Furthermore, DPPH, ABTS Nitric LD50 In conclusion, this suggests potency well safety crude over seeds.
