In this study, the antioxidant activities of juice, peel, and seed parts of pomegranate were investigated by using DPPH scavenging activity, β-carotene bleaching method, reducing power, and metal chelating activity. Sample of pomegranates which are named Punica granatum L. cv. Hicaznar, genotype 19-121, genotype 17-67, and genotype 19-66 obtained from BATEM (West Mediterranean Agricultural Research Institute) in Anlalya. The EC50 values of DPPH scavenging activities in peel extracts (PE) had 23. 4-fold higher than the juice extracts (JE), and the seed extracts (SE) had 2. 3-fold higher than JE. The reducing power in peel extracts was found to be 4. 7-fold higher than SE and 10. 5-fold higher than the JE. The highest metal chelating capacity (37. 22%) was determined in peel, while the lowest (7. 151%) in seed. Generally, in peel, the total polyphenol, flavonoid, tannin contents, and in juice, the total polyphenol, anthocyanin, tannin contents, and acidity significantly affected to antioxidant activities. © 2012 The Korean Society of Food Science and Technology and Springer Netherlands.
