ABSTRACT: In the present investigation an attempt has been made to experimentally test the anti-microbial efficacy of a common wild plant, Lantana camara against Staphylococcus aureus. Both root and stem extracts were tested separately using different solvents for the extraction of active soluble principles. The highest ZOI in the extract of root was found to be 25 mm under 200 mg/ml concentration of acetone followed by 23 mm under 100mg/ml concentration of the same solvent. All the concentrations of the root with ethyl acetate extract were found to be least effective. The anti-microbial efficacy of the chloroform extract was next to that of acetone extract. The acetone extract of stem (200 mg/ml) was found to be highly effective against Staphylococcus aureus, which gave ZOI of 24 mm, followed by 20 mm under 100 mg/ml concentration of the same solvent and that of 100 mg/ml of benzene extract. The most ineffective extract was that of petroleum ether in which only a very small zone (8 mm) of inhibition was recorded for 50 mg/ml whereas both 100 and 200 mg/ml concentrations proved ineffective. In rest of the solvents both root and stem extracts exhibited varying degree of inhibitory activity.
