Evaluation of the Antibacterial Potential of Azadirachta indica Leaf Extracts
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2012, Vol 2, Issue 1
Abstract
The current investigation was designed to evaluate the antibacterial activity of leaf extracts of Azadirachta indica (Meliaceae) commonly known as neem against some gram-positive (Staphylococcus aureus) and gram-negative (Escherichia coli and Pseudomonas florescence) bacteria by disc diffusion method. Phytochemical studies show the presence of saponins, tannins, glycosides, flavonoids, steroids, coumarins and alkaloids. Ethanol extracts (50 mg/mL) exhibited the highest activity 12, 20, mm zone of inhibition [s. aureus and E. coli], Petroleum-ether extracts (or control) exhibit the least activity
