Hydrogen peroxide scavenging activity of grape (Vitis vinifera) methanolic extract

Journal Title: Food Research - Year 2017, Vol 1, Issue 2

Abstract

Grape is a fruit used since antiquity by man for its therapeutic virtues due to its richness in antioxidant molecules that can replace synthetic antioxidants such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) and tert-butylhydroquinone (TBHQ) which are dangerous for human health. Antioxidant activity of methanolic grape extract was evaluated using the hydrogen peroxide (H2O2) scavenging activity. The high percentages of H2O2 scavenging activity were obtained for black varieties (Gros noir and Muscat noir) with 72.86 and 65.72, respectively. The white variety (Victoria) has exhibited a percentage of 38.57 which is close to that obtained for Cardinal 2 (38.64) and higher than that obtained for Cardinal 1 (30.64) which is red variety. These results suggest that grape extracts may serve as a potential source of natural antioxidant for food preservative and pharmaceutical application even black, red or white varieties.
