Phyto chemical screening and antibacterial activities of Allium cepa bulb and Allium sativum bulb extracts was investigated and compared. Analysis of data confirms that antibacterial activity was maximum at 505g/ml of Allium cepa bulb and Allium sativum bulb ethanolic extract against Bacillus subtilis, Bacillus pumilis, Escherichia coli and Pseudomonas aeruginosa compared with 505g/ml of ciprofloxacin standard. These results suggest that the both ethanolic extracts of Allium cepa bulb and Allium sativum bulb have similar potent antibacterial activity due to the presence of flavonoids.
