Abstract
In the present study the methanolic extracts from Ficus retusa L. (fruits), E benghalensis L. (fruits), Schinus terebinthifolius Raddi (fruits), Erythrina humeana (bark), Delonix regia (bark), Lantana camara L. (leaves), Syzygium cumini L. (leaves), and Cupressus sempervirens L. (leaves), and the water soluble exudate gum from Meryta sinclairii (wood exudate gum) were evaluated for their antibacterial against four human pathogenic bacteria namely; Micrococcus luteus, Staphylococcus aureus, Acinetobacter baumannii and Pseudomonas aeruginosa. The bioassay was evaluated at a concentration of 2000 mu g/mL using the disc-diffusion method. The extracts were shown a variation in the inhibition zones ranges from 7-22 mm. The present results could be useful for further work related to the bioactivity agents for controlling the infectious diseases caused by human bacterial pathogens.
