Description
Summary:Objective:To investigate the antibacterial activity and phytochemical screening of the aqueous.methanol and petroleum ether leaf extracts of Merremia emarginata(M.emarginata).Methods:The antibavterial activity of leaf extracts of M.emarginata were evaluated by agar well diffusion method against four selected bacterial species.Results:The presence of tannins,flavonoids,amino acids,starch,glycosides and carbohydrates in the different leaf extracts was established.The methanol extract was more effective against Baciilus cereus and Eseherkhia coli,whereas aqueous extract was more effective against Staphylococcus aureus and Pseudomonas aeruginosa.Condusions:The results in the present study suggest that M.emarginata leaf can be used in treating diseases caused by the tested organisms.
