In the present study ethanolic and methanolic extracts of leaves of Piper betel were screened for antibacterial properties against pathogenic bacteria namely Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. Both the extracts were effective against the used pathogens but methanolic extracts were found to be more effective in comparison to ethanolic extracts. Methanolic extracts showed maximum zone of inhibition of 25mm against Staphylococcus aureus followed by a zone of 17.5mm against Pseudomonas aeruginosa and 15mm against Escherichia coli. Ethanolic extracts showed a maximum zone of 17mm against Escherichia coli followed by a zone of 16mm against Staphylococcus aureus and 14mm against Pseudomonas aeruginosa. MIC was found to be ranging between 0.0021mg/ml to 8.196 mg/ml in both the extract.
