ANTIMICROBIAL ACTIVITY OF COCONUT SHELL OILAbstract
Coconut shell oil was extracted from raw coconut shells, collected from Thiruvallur District. These were extracted using various solvents based on the polarity which includes ethanol, chloroform, acetone, petroleum ether and aqueous. The antibacterial activity against the growth of Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa and Salmonella typhi was done. The antifungal activity against the growth of organisms such as Epidermophyton floccosum, Aspergillus niger, Penicillium, Microsporum canis, Candida albicans and Aspergillus flavus were tested. The extracts were compared with standards like novobiocin, amoxillin and ketoconazole for antibacterial and antifungal activity respectively. The results indicate that zone of inhibition increased when increasing the concentration of the extracts. Among the five extracts of coconut shell oil the ethanolic extract exhibited maximum antibacterial activity against six bacterial strains. Ethanol and petroleum ether extract showed maximum inhibitory activity against Epidermophyton and Candida albicans. This study showed that coconut shell oil possesses antimicrobial activity.
