Abstract
Pomegranate is recognized such as a unique fruit having noticeably high antioxidant ability and health-promoting compounds. The huge diffusion of new cultivars needs the information of all plant features to satisfy the market request. The objective of the present study was to determine the bioactive compounds and antioxidant ability from peel, leaf and seed of 47 pomegranate cultivars grown in Iran. Pomegranate peel samples showed a high level of total phenol, flavonoid, flavonol, soluble sugar, ascorbate and antioxidant activity than leaf and seed. In peel samples, the highest level of total phenol, flavonol, flavonoid, anthocyanin, soluble sugar, ascorbate and antioxidant activity was found in White Sweet Tochal, Shirin Shahsavar Sar Yazd, Zard Baghmalek, Atabaki Nayriz, Nabati Shahreza, Hasebe Sar Yazd and Baghmalek, respectively. The leaf of Germeze Baghmalek, Shirin Ajan, Pust Sefeede korak, Alake Saveh, Robab Neyriz, Syahe Dane Gome and Shirin Neyriz had maximum level of total phenol, flavonol, flavonoid, anthocyanin, soluble sugar, ascorbate and antioxidant activity, respectively. The strongest level of total phenol, flavonol, flavonoid, anthocyanin, soluble sugar, ascorbate and antioxidant activity in seed was in Nabati Shahreza, Alake Gharegae, Aarosak Korak, Sabz Baghmalek, Pust Sorkh Sar Yazd, Pust Nazok Saveh and Shirin Taft, respectively. The correlation values between the bioactive compounds (phenol, flavonol, flavonoid, soluble sugar and ascorbate) and antioxidant capacity of the peel, leaf and seed, show that this metabolites are among the constituents contributing to the antioxidant ability of pomegranate. The data of current research can help to choice the pomegranate cultivars for commercial production.
