Pomegranate fruit is to rich in phenolic compounds and antioxidant properties and can show difference in the composition according to cultivars, part of fruit, environmental conditions and analysis method. Therefore, the aim of the present study was to analyse and to compare the chemical composition and antioxidant properties from the different parts of fruit Valenciana and Wonderful pomegranate cultivars. The pomegranate fruits were separated into aril, peel, membrane and seeds manually and analysed by phenolic compounds, flavonoids, antioxidant activity (DPPH method), soluble solids, titratable acidity, pH and vitamin C content. The phenolic content and flavonoids were significantly affected by pomegranate cultivars and part of fruit. In the part of fruit showed differences by the DPPH, however the pomegranate cultivars not showed. Significant differences were revealed between the pomegranate cultivars and part of fruit for total soluble solids, titratable acidity and pH. The differents part of pomegranate fruit (aryl, membrane peeling and seed) has influences on the phenolic content, flavonoids, antioxidants, total soluble solids, pH and acidity. The cultivar does not show diffences on the antioxidants by DPPH method, pH and vitamin C.This study suggests the importance of the selection the different parts of fruit and cultivar that will be used as raw material in the preparation of pomegranate products with higher antioxidant activities.
