Antimicrobial study of leaves and bark extracts of Diospyros virginiana

The in vitro antimicrobial activity of methanolic, chloroform and petroleum ether extracts of Diospyros virginiana were evaluated against selected pathogens showing moderate activities by disc diffusion methods against P.aeruginosa, Staphylococcus aureus, Proteus vulgaris, Pseudomonas fluroscence and S.pyogenes and the As.oryzae, As.niger, Penicillium viridicatum, C.albicans and Trichoderma viride. The antimicrobial activity of leaves methanolic extract showed best activity varied from 34–21 mm. Minimum inhibitory concentration test was performed by modified disc diffusion method showed the least activity at leaf extract. It might be concluded from the study that the potential of this plant to produce useful antimicrobial compounds is great and must be better explored.
