Herbal medicinal plants are widely used as a therapeutic medicine for the treatment of wide range of various types of diseases all over the world. Terminalia arjuna is an important plant which is used as folk medicinal plant for the treatment of various complications. The present study was aimed to determine the antioxidant activity of the petroleum ether extract of the plant. The phytochemical analysis of Terminalia arjuna has indicated the presence of flavonoids and carotenoid. Petroleum ether extract of Terminalia arjuna leaves was evaluated for antioxidant property by DPPH scavenging assay method. The different concentration of the extract i.e. 50µg/ml, 100 µg/ml, 150µg/ml and 200µg/ml were showed 36.6%, 39.2%, 56.9% and 63.3% inhibition activities respectively, while BHT was used as standard which showed 79.4% inhibition activity. The above result suggested that Terminalia arjuna have some antioxidant potential activity. The statistical analysis showed significant result. Finally, we concluded that the antioxidant activity of the plant is may be due to the presence of various bioactive secondary metabolites.
