STUDY OF ANTIMICROBIAL ACTIVITY OF SOLVENT EXTRACTS OF LEAVES OF LANTANA CAMARA
Sonia Ruhela*, Vandana Shrivastava and Abhishek Mathur
Medicinal plants are gaining global attention owing to the fact that the herbal drugs are cost effective, easily
available and with negligible side effects. The beneficial effects of the medicinal plants in health care can be well
judged from the WHO estimate that around 80% of the world population uses them in some form or the other. It is
important to note that homeopathy and modern medicine have their roots in medicinal plants. In the present
investigation, different polar (aqueous and methanolic) and non polar (hexane) solvent extracts of leaves of
Lantana camara at 250μg/ml were investigated for antimicrobial potential against different microbial strains viz.
Staphylococcus aureus, Bacillus subtilis and Bacillus licheniformis. The results showed that methanolic and
aqueous extracts have significant antimicrobial activity in comparison to that of hexane extracts. Amongst all these
extracts, methanolic extract had significant antibacterial activity against Bacillus subtilis (45 mm) and Bacillus
licheniformis (50 mm) while aqueous extract was found to have antibacterial activity against Staphylococcus
aureus (43 mm) while hexane extract was found to have no antibacterial activity against all the microbes studied.
The Phytochemical screening results of the aqueous and methanolic extracts of the leaves of the plant showed the
presence of tannins, steroids, saponin, glycosides and reducing sugars while alkaloids and flavanoids were found to
