Potential research on natural products has expanded a wide popularity due to the potential of discovering bioactive molecules. The antioxidant properties confined in plants have been proposed as one of the tool for the observed beneficial properties for various diseased conditions. Therefore, the present study has been accomplished to phytochemical testing and evaluation of antioxidant capacity of 70% ethanolic extract of Albizia lebbeck Leaves (EEAL). The antioxidant property of 70% EEAL was tested by using reducing power and free radical (superoxide, hydroxyl and nitric oxide) scavenging models (in vitro). Albizia lebbeck ethanolic extracthas shown dose dependent antioxidant activity in all the models of the study (i.e. 82.03%-reducing power, 79.12%-superoxide, 49%-hydroxyl scavenging activity at 100mcg concentration). The 70% EEAL possess significant antioxidant activity. The antioxidant property may be attributed to the polyphenolic compounds like flavonoids and tannins that are present in the 70% EEAL.
