The in vitro antibacterial activity of ethanol, methanol and ethyl acetate extracts of M. citrifolia (fruit, leaf and stem) are presented in Table 1, and V. trifolia and C. odorata (leaf) are shown in Table 2. The results obtained from the disc diffusion assay showed that the plant extracts posses antibacterial activity against the tested microorganism. The extracts showed good inhibitory activity on almost all the microbes tested. Among the three solvents tested, methanol extracts showed maximum inhibitory potential against all the tested organisms than ethanol and ethyl acetate extracts. Chloramphenicol is used as a standard antibacterial agent inhibited the growth of all the organisms and the zones of inhibition produced were far greater than those produced by the different extract concentration. When comparing among the plants, C. odorata extracts showed maximum antibacterial activity than M. citrifolia and V. trifolia.
