The antioxidant activity of leave and peels crude juices on sunflower oil oxidation was assessed by three methods that is, 2, 2-diphenyl-1-picryl-hydrazyl (DPPH), reducing power and designation of the induction period by rancimat apparatus. The results indicated the amounts of polyphenols and flavonoids in crude peels juice were markedly higher than the crude leave juice.

The antioxidant activity of crude peels juice was higher than that of crude leave juice. Statistical analysis demonstrated that there is a positive correlation between polyphenolic content and the antioxidant activity of pomegranate crude juices.

The present results stressed on the use of pomegranate crude juices as a natural antioxidant since it is nearly priceless, caused no harmful effect on human being health and induced powerful antioxidant effect compared to the well known BHT, the synthetic antioxidant.
