N2 - The objective of this study was to characterize the antioxidant properties of ethanol extracted from leaves of Jatropha curcas and to determinate the compounds. The IC50 values of DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt) were found to be 7.47 and 6.6 μg/ml, respectively, for the extracts. The reducing power of the extracts increased from 0.09 to 0.16, respectively, for 1-32 μg/ml of standard reagent. The assignment of the flavone compounds using HPLC-DAD-MSn was based on the evaluation of their UV-Vis absorption maxima (λmax) and mass spectral analyses. Tentatively, 4 compounds (orientin, vitexin, isovitexin, rhoifolin) were identified.
