PHYTOCHEMICAL SCREENING AND ANTIBACTERIAL ACTIVITY OF JACQUEMONTIA CAERULEA

The study was performed to examine the antibacterial activity of Jacquemontia caerulea against gram-positive bacteria like Staphylococcus aureus and gram-negative bacteria like Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis, and Vibrio cholera. The antibacterial activity of various extracts of the plant at different concentrations (5,10,15,20 µg/ml) o was investigated by using disc diffusion method. Phytochemical screening of extracts showed the presence of secondary metabolites like alkaloids, flavonoids, glycosides, saponins, tannins, and triterpenes. The extracts showed significant antibacterial activity. The maximum zone of inhibition was shown by methanolic extract at 20µg/ml concentration against Staphylococcus aureus. The antibacterial activity might be due to the presence of secondary metabolites.
