Leaves possess glycosides, large quantities of flavonoids, tannins and minerals. Flavonoids have been found to possess antioxidant, anti-inflammatory and lipid lowering effects. This work was carried out to investigate the antioxidant activity and free radical scavenging capacity of leaf extract of terminalia arjuna prepared in ethanol. The extraction yield of extract was found to be 17.14gm on dry weight basis. From the DPPH radical scavenging activity, phosphomolybdenum method and hydrogen peroxide scavenging method, it can be concluded from the results that arjuna extract was good source of natural antioxidants.
