Abstract:
In the present study an attempt was made to identify the presence of phytochemicals in the Aqueous, Ethanol, Methanol and Petroleum ether extracts of leaves of Lantana camara. The leaves extracts were studied qualitatively to ascertain the presence of phytochemicals such as Alkaloids, Phenols, Tannins, Saponins, Terpenoids, Flavonoids, Oils, Resins, Gums, Carbohydrates and Amino acids by adopting standard methods. The antibacterial activities of L.camara leaves extracts were tested against pathogenic bacteria Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia and Salmonella paratyphi A by using the agar disc diffusion method. Among the solvents used, Methanolic extracts of L. camara demonstrated higher antibacterial activities against E.coli (2.63±.033 mm) in 500 μl concentration. Fractions were separated from the extracts of hexane and ethyl-acetate by using the column chromatography and thin layer chromatography for further analysis.The study provided referential information for the identification of the leaves extracts of L. camara.
