Abstract

This study investigates the in vitro antibacterial activity of coconut oil on selected clinical and pure bacterial isolates. Clinical samples were isolated from the people of Ras Al Khaimah, United Arab Emirates. Biochemical examination of the microorganisms was done according to standard methods. Pure bacterial cultures were provided from LTA srl Italia. In this research work, an effort has been made to highlight the valuable properties of Cocos nucifera oil, in order to rationalize the use of coconut oil against bacteria. Experiments were performed by agar well diffusion method. Ciprofloxacin was used as a standard antibiotic. The assay of antibacterial activity of clinical isolate of Streptococcus species showed the highest susceptibility to coconut oil while Escherichia coli had the least. This study endorses the use of coconut oil as therapeutic agent since it contains lauric acid which is bactericidal. The utilization of coconut oil should be promoted as a functional food and the use of coconut seed flesh in our diets should be encouraged for health-supporting functions. Further studies should be done on the oil and its derivatives both in vitro and in vivo to unveil their mechanism of action.
