Evaluation of Antibacterial Activity and Phytochemical Screening of Azadirachta indica Leaves Extracts Against Staphylococcus aureus

Azadirachta indica is an Indian tree well known for its several pharmacological activities, including antimicrobial activity. A. indica leaves extract was used to screen antibacterial activity against S. aureus. The methanol extract of leaves of A. indica was prepared and its phytochemical screening  was performed. The phytochemical analysis exhibited the presence alkaloids, polyphenol, tannins, flavonoids and glycoside in extract. The methanol extract of A. indica leaves tested against S. aureus using disc diffusion method. Gentamicin was used as standard and compared the effect of antibacterial activity of methanol extract. The methanol extract of A. indica leaves demonstrated potent antibacterial activity against tested bacteria.
