Pomegranate juice and related products have been long used either in traditional medicine and as nutritional supplements claiming beneficial effects. Although there are several studies performed on this edible fruit, only a few studies have been performed with pomegranate juice or its commercial products. In the present study, juices from three different varieties of pomegranate (one edible and two ornamental) as well as four phytochemicals naturally contained in the pomegranate fruit (ellagic acid, punicalagin, gallic acid and caffeic acid) were screened for their antioxidant capacities, through the oxygen radical absorbance capacity (ORAC) and the cellular antioxidant activity (CAA) assays. The aim of this work was to evaluate the antioxidant effects of pomegranate juice and its antioxidant molecules on cellular models, to assess their efficiency of protection against peroxyl radicals under physiological conditions. The pomegranate juices and the selected antioxidant molecules were successfully absorbed by human cells. Although, the results indicate that the CAA measured in HaCat cells are not correlated with the ORAC values. Additionally, the protective effect on human DNA against oxidative stress was demonstrated with the pomegranate juice.
