Phytonutrients Potential Properties of Graviola Leaves Extract

Abstract

Recent studies indicated that regular consumption of antioxidant rich foods reduce cellular oxidative stress and protect against health related problems. Annona muricata, is a tropical fruit, commonly known as Graviola, which has been identified as a rich source of bioactive compounds and is considered as an integral part of folklore medicine. The use of Graviola leaves as a therapeutic agent is recently accelerated, yet there is scarce scientific evidence justifying its use. This study aimed to assess the in vitro antioxidant properties and phytonutrients content of the Omani cultivated Graviola leaves. Our study revealed that Graviola leaves extract is rich in phytonutrients content (The total phenolic content was 16.82 mg Gallic acid equivalent (GAE)/g dry solid and the total flavonoid content was 7.79 mg Catechin equivalent (CE)/ g dry solid) and acted as a potent free radical scavenger and provided protection against H2O2-induced oxidative stress.
