Abstract:

An antioxidant activity study of phenolic compounds from young and ripe Pingguoli pear peels was carried out by DPPH free radical, hydroxyl free radical and nitrite scavenging assays. It was found that phenolic compounds from Pingguoli pears had good scavenging effect against all DPPH and hydroxyl free radicals and nitrite and that the phenolic extract from young fruit peels was superior to that from ripe fruit peels.

Key words: Pingguoli pear, phenolic compounds, antioxidant activity
