A Study on Antibacterial Properties of Rosa indica against Various Pathogens

In the present study Antibacterial properties of Rosa indica was explored against different pathogens. Antimicrobial components were extracted by solvent extraction wherein methanolic and ethanolic extracts were prepared. The antibacterial nature of extracts was assessed by agar well diffusion method. The methanolic extracts of Red rose petals were found to be most effective against all the pathogens used, they gave a zone of inhibitions of 27 mm against Escherichia coli, 26mm against Pseudomonas aeruginosa, and 25 mm against Staphylococcus aureus which was far better than the zone of inhibition given by the standard antibiotic Tetracycline used throughout the study. The MIC(minimum inhibitiory concentration) for the methenolic as well as ethanolic extracts were determined and it was found to be ranging between 0.12 μg/ml to 0.65 μg/ml.
