Phytochemical screening and antioxidant activity of pomegranate peels and leaves of peach

Abstract

Pomegranate (Punica granatum L.) is a nutrient-dense food rich in beneficial phytochemicals. The aim of this study is to investigate the antioxidant activity, total phenolic, and flavonoids content and compared them with the antioxidant activity of Peach leaves. The phytochemical screening was assessed by using different extracts: ethanol, butanol, and ethyl acetate. The total phenolic content was determined spectrophotometrically by Folin-Ciocalteu's method and the total flavonoid content were also determined by using the aluminum chloride complex formation assay. Results showed that the amount of total phenolic and flavonoid content in Pomegranate was higher than those in peachʼs leaves. They ranged from 0.352 to 1.35µg/ml and varied from 0.223 to 0.701µg/ml respectively. Also, the extracts of Pomegranate possessed stronger antioxidant activity than extracts of leaves of peach in radical scavenging activity by DPPH˙ where the DPPH˙ radical scavenging activity ranged from 18.5% to 45% in ethyl acetate extract of Pomegranate.
