PHYTOCHEMICAL ANALYSIS AND ANTIBACTERIAL ACTIVITY OF IPOMOEA INDICA PLANT LEAF EXTRACTS
Objective: The objective of this study was to phytochemical analysis and antibacterial activity of the Ipomoea indica plant leaves extracts.
Methods: The crude powder of the plant leaf samples of I. indica was extracted using methanol and aqueous solvents and subjected to qualitative phytochemical analysis. The antibacterial activity of the aqueous and methanol extracts was tested at different for concentrations. The extract was tested against bacterial strains like Staphylococcus aureus, Enterococcus faecalis, Salmonella typhi, and Escherichia coli.
Results: The phytochemical screening revealed the presence of alkaloids, flavonoids, terpenoids, glycoside, reducing sugars, saponins, steroids and tannins in the solvent extract. The antibacterial activity was performed by using the disc diffusion method, where the largest zone of inhibition was obtained with aqueous extract 75Âµ concentration against Salmonella typhi (26 mm). The antibacterial activity was compared with the standard antibiotics like Streptomycin.
Conclusion: This study suggests that the aqueous extract of the I. indica leaves possesses bioactive compounds with antibacterial activity against the bacterial strains, which can be used to formulate new antibacterial drugs for disease control.
