The extract of Azadirachta indica show different properties like antibacterial, antifungal, antoxident etc. In this work we prepared extract in different solvent i.e benzene, acetone, toluene, ethyl acetate, ethanol and beutyl alcohol. Phytochemical analysis of plant extract also gave positive result for saponins, tannins, phenols, proteins, glycoside, terpenoids, carbohydrate, flavanoids, alkanoids. The aim of this study that screen out the active components and test the antibacterial activity of extract in different solvents as benzene, acetone, toluene, ethyl acetate, ethanol, beutyl alcohol. The acetone extract showed the maiximum bacterial growth nhibition 58.77% against E. colistrains. Therefore the Azadirachta indica leaf and other parts of this plant use for different purpose like antimicrobial, antioxidant in the form of powder, tablet and micro solution.
