Evaluation of the antioxidant and hepatoprotective activity of Terminalia catappa

The free radical scavenging and antihepatotoxic activity from Terminalia catappa was studied. Treatment with T. catappa water extracts showed antihepatotoxic activity against CCl4-induced toxicity in the rat liver that was tested. The crude drug also exhibited anti-oxidant effects in FeCl2-Ascorbic acid induced lipid peroxidation in the rat liver homogenate. Moreover, the superoxide radical scavenger effect of T. catappa was demonstrated using electron spin resonance (ESR) and spintrapping technique. The results indicate that T. catappa possesses good antihepatotoxic activity and superoxide radical scavenger activity.
