Comparison Studies of Phyto Chemical Screening and Antibacterial Activities of Allium cepa bulb and Allium sativum bulb Extracts

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.
