Abstract

In the present study, investigation of phytochemical constituents of Cymbopogon citratus (DC.) The aim of the present study, to investigation of phytochemical analysis and antibacterial activity of methanolic extract of Memecylon capitellatum L. leaves active against seven bacterial species. The bacterial species are Pseudomonas auruginosa, Vibrio cholerae, Vibrio parahaemolyticus, Klebsiella pneumonia, Escherichia coli, Salmonella typhi, and Staphylococcus aureus were cultured in nutrient broth and maintained in nutrient agar. The antibacterial activity of M. capitellatum L. leaf extracts was measured by agar well diffusion method. The results of the present study of M. capitellatum leaf showed the largest zone of inhibition active against Saimonella typhi and followed by V. parahaemolyticus and S. aureus, respectively. The conclusion of the results from the study suggests that the leaves of M. capitellatum showed that good antibacterial activity against the selected bacterial species. Our results suggested that M. capitellatum could be used as alternatives antimicrobial agents for treatment of bacterial infections of human being.
