Evaluation of In vitro Antioxidant Activity of Methanol and Aqueous Extract of Annona squamosa (L) stems bark.

Abstract

The present work was conducted to evaluate the antioxidant activity of the stem bark of Annona squamosa by means of various methods [DPPH scavenging, ABTS radical scavenging, nitric oxide radical scavenging, hydroxyl radical scavenging and superoxide radical] using methanolic and aqueous extracts. The results showed that extracts of Annona squamosa possess significant Antioxidant property in both solvents. Hence, it could be a source of natural antioxidant that could have greater importance for slowing oxidative stress related degenerative diseases.
