The present investigation was undertaken for in vitro screening of antibacterial activities of acetone, benzene and ethyl acetate extract of Rosemary leaf powder and Black cumin seed powder. In vitro antibacterial efficacy of selected plants was assessed by well diffusion method against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. The results showed that ethyl acetate and acetone extract of black cumin seed powder were most effective against the Staphylococcus aureus. The ethyl acetate extracts of Rosemary leaf powder was most effective against the Escherichia coli, while benzene extract of both herbs remained ineffective against Escherichia coli. The ethyl acetate extracts of both herbs were effective against Pseudomonas aeruginosa, whereas acetone and benzene extracts of both herbs remained ineffective against Pseudomonas aeruginosa respectively. The Present study showed that these plants possess compounds with antibacterial activity.
• Rosemary leaf powder extracts showed effective antimicrobial activity against S. aureus and E. coli.
• Black cumin seed powder extracts showed effective antimicrobial activity S. aureus.
