Determination of the Phenolic Contents and Antioxidant Activities of Some Pomegranate (Punica granatum L.) Cultivars Grown in Şanlıurfa

Abstract

In this research; total phenolic content, total flavonoid content, total anthocyanin content and antioxidant activities in fruit juices and seeds of Hicaznar, Katırbaşı, Devedişi, Suruç and Suruç Karası pomegranate cultivars obtained from the Central, Bozova, Harran and Suruç districts of Şanlıurfa were investigated. As a result of the study, the total amount of phenolic substance in the juice taken from pomegranate varieties is between 26.60-40.43 µg GAE g-1, the total amount of flavonoids is between 572.66-1150.83 μg QE g-1, the total antioxidant capacity is between 89.47-96.38%, the total anthocyanin amount is between 0.84-24.12 mg cyanidin 3-glycoside L-1 between, the total amount of phenolic substance in the seeds is between 95.39-146.44 µg GAE g-1, the total amount of flavonoids is between 983.57-1830.18 μg QE g-1, the total antioxidant capacity is between 7.76-26.64%, the total amount of anthocyanin is 0.19-3.51 mg cyanidin 3-glycoside L-1 ıt was found to be between. The highest total phenolic content and total flavonoid content among all cultivars were measured in seed samples, and total antioxidant capacity and total anthocyanin content in fruit juice samples. In the light of the results obtained from the research, it was seen that the juice and seeds of pomegranate varieties have rich phytochemical content and contain high amounts of phenolic components beneficial for human health.
