Antioxidant properties of the phenolic fraction of Sardinian wines

Abstract

The aim of this study was to compare the antioxidant capacities of the phenolic fraction of wines from Vitis vinifera grapes cultivated in Sardinia (three native: Cannonau, Malvasia, Vermentino and three non-native types: Cabernet-sauvignon, Chardonnay and Sauvignon), in simple in vitro systems. All the extracts showed a significant antioxidant activity, beeing the native wine extracts the most active in inhibiting the lipid peroxidation process.
