Abstract

The antioxidant activity of pomegranate fruit peels was evaluated using in vitro tests. 80% methanolic extracts (ME) of peels had higher yield (45.4%) and total phenolics (27.4%) than water (WE) or ether extracts (EE). The reducing power of ME was more potent (P < 0.05) than either WE or EE. The DPPH radical scavenging activity (%) of ME was stronger than that of α-catechin. Pomegranate peels contained phenolics, exhibited DPPH scavenging activity and reducing power.
