Fruits are a source of antioxidant compounds, such as phenolics, vitamins and carotenoids, which contribute to their chemo preventive potential. The mentioned compounds, which scavenge free radicals, may reduce the level of oxidative stress and prevent the oxidation of biomolecules, that would break the reaction chains of pathogenesis in the deterioration of physiological functions, which could occur in the coronary heart diseases and cancer [1]. Apart from their biological properties, natural antioxidants are also of interest in the cosmetic, pharmaceutical and especially in food industries, since they can be also used as natural antioxidants, Nutraceuticals, prebiotics, dyes. [2]

The present work evaluated phenolics, and flavonoids contents (quantity) of organic pomegranate juice, peel and seeds cultivated in the Northeastern part of Algeria, in vitro antioxidant activity, using: CUPRAC, GOR, PHENYL, DPPH, ABTS assays and enzymatic activity: α-glycosidase were also investigated and confirms traditional uses of pomegranate parts[3]. Furthermore, a comparative study of all these essays on different pomegranate's parts tests will be given.

However, further investigations should assessed safety of by products "seeds, arils and peels" at efficient but non toxic doses, if we want to use it as added value in our daily feeding .
