Antioxidant activity of pomegranate peel and seed powder extracts

Abstract

The present study was devised to explore the antioxidant activity of pomegranate peel powder (PPP) and pomegranate seed powder (PSP). Total phenolic content was determined by Folin Ciocalteu reagent method and antioxidant activity by DPPH and ABTS radical scavenging activity methods. The study revealed that the total phenolic content (mg GAE/ g) of PPP was significantly higher (P 0.05) in the methanolic extracts compared to the water extracts. The percent DPPH-RSA of PPP was significantly higher (P 0.05), the values being numerically slightly higher in the former. Thus it was concluded that pomegranate peel and seed powder could find several applications as functional food ingredients due to the antioxidant properties.
