Abstract

The in vitro antibacterial activity of various solvents and water extracts was assessed on Staphylococcus aureus. The zone of inhibition as determined by agar well diffusion method varied with the plant extract, the solvent used for extraction, and the organism tested. The results obtained in the agar diffusion plates were in fair correlation with that obtained in the minimum inhibitory concentration tests. The minimum inhibitory concentration of rose extracts was found in the range of 1.56-6.25 mg/ml for the multi-drug resistant Staphylococcus aureus isolates tested whereas higher values (6.25-25 mg/ml) were obtained against the multi-drug resistant isolates. Qualitative phytochemical analysis demonstrated the presence of tannins and saponins in all plants tested.
