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

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 H₂O₂ induced oxidative stress in Drosophila melanogaster flies was assessed.

Consumption of Amaranth leaf extract was associated with increased survival on exposure to H₂o₂ in a dose dependent manner in Drosophila melanogaster flies. The study concludes that the ethanolic extract of Amaranth leaves offer protection against hydrogen peroxide-induced oxidative stress.
