Morinda Citrifolia is one of the most important traditional Polynesian medicinal plants. This small evergreen tree is native from South Eastern Asia to Australia and now it has a Pantropical distribution. It has antifungal, antibacterial, antiinflammatory and antiviral activities. Morinda citrifolia L. was studied for its antimicrobial activity. The leaves of this plant were dried, powdered and different extracts were prepared using different solvents like benzene, chloroform, ethyl acetate, ethanol and water. Four organisms, namely E.coli, Staphylococcus aureus, Candida albicans and Aspergillus niger, were used for investigation. The activity of each solvent extract was checked on each organism by disc diffusion method and then the zone size of each was measured. The results of our antimicrobial assay revealed that plant extracts showed inhibitory activity against the tested organisms.
