Phytochemical analysis and in vitro antioxidant activity of Terminalia catappa

Abstract

The present study evaluates the phytochemical constituents and in vitro antioxidant potential of Terminalia catappa Linn. A qualitative phytochemical analysis of six solvent extract methanol, ethanol, petroleum ether, chloroform, 1%chloroform and ethyl acetate was performed for the presence of phytochemical constituents. Among six extracts methanol has been found to possess the highest phytochemical constituents when compare others. Further, the antioxidant activity of methanol extracts of T. catappa was evaluated by various antioxidant assays which include DPPH assay, nirtic oxide assay, reducing power assay and H₂O₂ assay. In all the tested methods T. catappa has been found to possess the antioxidant activity in a dose-dependent manner. The present study revealed that T. catappa is very rich in phytochemicals and a good source of natural antioxidants.
