ABSTRACT

Albizia lebbeck is very important medicinal plant; it is used in Ayruvedic medicine. In the present study established to find the phytochemical constituents and antioxidant property of various extracts of Albizia lebbeck were performed. The bark was shad dried and powdered. The powdered bark were defatted with methanol in Soxhlet apparatus and then extracted with absolute methanol for 96 hours separately in Soxhlet apparatus. The results of preliminary phytochemical screening of the ethanolic extract of AL revealed the presence of alkaloids, glycosides, steroids, flavonoids, saponins, tannins, carbohydrates and reducing sugar. The antioxidant activity of the ethanolic extract was measured 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity and the total antioxidant capacity of the ethanolic extract of Albizia lebbeck were determined. The ethanolic extract yielded the most significant levels of antioxidants and howed high free radical scavenging activity. Furthermore, studies on the isolation of constituents from the bark extract are biological activities under way for its better exploitation.
