Abstract
Morinda citrifolia is one of the most important traditional polynesian medicinal plant. This small evergreen tree is native of South Eastern Asia to Australia and now it has pantropical distribution all over the world. This plant has antifungal, antibacterial, anti-inflammatory and antiviral activities. The present study aqueous, methanol and ethanol extraction of leaf extract of Morinda citrifolia was carried out since this method is more suitable for clinical study. The leaf extract was prepared by conventional extraction method and it was assessed with minimum inhibitory concentration (MIC) method against clinical isolate of Pseudomonas aeruginosa. In the present study have found that ethanol extracts showed better antibacterial activity against P.aeruginosa when compared to methanol extract. Aqueous extract showed no activity against P.aeruginosa by MIC method. Solvent control also showed no activity against P.aeruginosa .The overall results indicates, methanol and ethanol extracts of M.citrifolia ,some useful drugs may be develop for the treatment of infectious diseases caused by P.aeruginosa.. The results revealed that plant extracts have inhibitory activity against the tested organism.
Keywords: Morinda citrifolia, Antibacterial activity, Aqueous,Methanol, Ethanol leaf extract.
