Rezumat

The objective of this study was to determine the antioxidant properties of the oil obtained from the kernel of walnut variety belonging to the species Calaras. The antioxidant profile of walnut oil samples were evaluated by reaction kinetics and reducing power of the oil samples towards 1,1-diphenyl-2-picrylhydrazyl stable free radical (DPPH•). The principle of DPPH assay is to measure the free radicals generated from oils directly. The obtained results showed that antioxidant properties of walnut oil were in the range of 24.11 – 54.73 %. The DPPH assay is rapid and easy to use, feasible and accessible to be use for antioxidant properties evaluation of walnut oil.
