ABSTRACT

The present study is initiated to discover the antibacterial potential of the sub shrub Hibiscus hirtus L. The leaves of this traditional shrub were found to posses’ antibacterial activity, which were extracted using methanol as solvent and soxhlation as a method of extraction. The leaves were priorly investigated for their pharmacognostic, phytochemical amd physical parameters. The antibacterial activity of the methanolic leaf extract was carried at different concentrations on strains of gram positive and gram negative bacteria such as Staphylococcus aureus and Escherechia coli respectively by using agar well diffusion method or cup and plate method. The results were furnished as the zone of inbition obtained around each concentration of the extract and were compared with that of standard antibiotic used in the experiment, streptomycin.

Keywords: Antimicrobial activity, agar well diffusion method, methanolic leaf extract, pharmacognostic, phytochemical parameters.
