BIOLOGICAL ACTIVITY OF AZADIRACHTIN COMPOUND AND HEXANE EXTRACT OF MELIA AZEDARACH FRUITS AGAINST SOME BACTERIAL ISOLATIONS

Abstract

An activity of azadirachtin compound after separating it fromMelia azedarach fruits powder and purification as well as diagnosing it byIR,CC,TLC, against some pathogenic bacterial isolations which areStaphylococcus aureus , Proteus , Pseudomonas aeruginosa, Escherichia coli ,has been studied .This compound has proved its high activity to influence againstthese bacterial isolations and inhibated the diameter of inhibation it was23,18,17,22mm with concentration 50mg/ml respectively . An activity of hexaneextract of Melia azedarach fruits powder also has been studied to prove its goodactivity against same bacterial isolations but in diverse rates between it andazadirachtin compound extract since diameters of inhibition zone have reached13,19,21,12 mm with concentration 50 mg/ml respectively
