IN VITRO ANTIBACTERIAL ACTIVITY STUDY OF ROSA INDICA LINN. LEAVES EXTRACTS
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2011, Vol 2, Issue 7
Abstract
To know the in vitro antibacterial activity of both the ethanolic and methanolic extracts of the leaves of both Pink Rose and Maroon Rose varieties of Rosa indica (Family-Rosaceae), present study was conducted. Both the extracts of each variety were used at 1mg/ml, 5mg/ml and 20mg/ml concentrations. While both the extracts of Pink Rose variety did not produce antibacterial activity at 1mg/ml, Staphylococcus aureus and Escherichia coli were sensitive to both the extracts at 5mg/ml and 20mg/ml in a dose-dependent manner. However, both ethanolic and methanolic extracts of Maroon Rose variety were only effective against Staphylococcus aureus at 20mg/ml. Bacillus subtilis was resistant to both the extracts of Pink Rose and Maroon Rose varieties. Moreover, like tetracycline (positive control) both the extracts of Pink Rose variety were more or less equally effective against Escherichia coli at 20 mg/ml.
