Amaranth leaf extract protects against hydrogen peroxide induced oxidative stress in Drosophila melanogaster

Résumé

Abstract Objective Amaranths leaves are rich in ascorbic acid and polyphenol compounds which have antioxidant activity. The aim of this study was to evaluate their in vivo antioxidant activity. The effect of consumption of Amaranth leaf extract on in vivo antioxidant activity, catalase enzyme activity and H 2 O 2 induced oxidative stress in Drosophila melanogaster flies was assessed. Results Consumption of Amaranth leaf extract was associated with increased survival on exposure to H 2 o 2 in a dose dependent manner in Drosophila melanogaste r flies. The study concludes that the ethanolic extract of Amaranth leaves offer protection against hydrogen peroxide-induced oxidative stress.
