Abstract: Thirty-four Indian medicinal plants belonging to 28 different families were screened for potential antibacterial activity against 3 Staphylococcus species, namely Staphylococcus aureus, Staphylococcus epidermidis, and Staphylococcus subflava. Antibacterial activity of aqueous and alcoholic extracts was performed by agar disc diffusion method and agar well diffusion method. The alcoholic extracts were more active than aqueous extracts for all the plants studied. The most susceptible bacterium was S. aureus. The methanol extract of Woodfordia fruticosa showed the best antibacterial activity. The in vitro susceptibility testing of the studied staphylococcus strains was done against standard antibiotics.
