In vitro Antioxidant and Antibacterial Activity of Albizia lebbeck (L) Benth Stem Bark

Abstract

Nature provides various remedy for the management of different diseases since the existence of mankind. 80% of the world population still relies on nature as a main source of remedies for primary health care. The main aim of the present study was to evaluate in vitro antibacterial and antioxidant activity and preliminary phytochemical screening of the methanolic extract of Albizia lebbeck (L) Benth stem bark. Preliminary phytochemical screening showed the presence of alkaloids, saponins, glycosides, phytosterols, flavonoids and tannins. The presence of alkaloids, saponins, glycosides, phytost antioxidant activity of the stem bark extract was studied using DPPH free radical scavenging antioxidant activity of the stem bark extract was studied using DPPH free radical scavenging assay. Extract was shown to display a dose dependent free radical scavenging effect. In disc assay. Extract was shown to display a dose dependent free radical scavenging effect. In disc diffusion method, the methanol extract showed considerably good antibacterial activity against act showed considerably good antibacterial activity against Gram positive and Gram negative bacteria.
