ABSTRACT

Objective: It has been postulated that geographical locations of the herbs affect the constituents of their essential oils and thus the degree of their antimicrobial action. This study examine Six different oils extracted i.e. fresh carpel oil of Zanthoxyulum rhetsa Roxb DC, Dried carpel oil of Zanthoxyulum rhetsa Roxb DC, Eucalyptus oil, Clove oil, Palmarose oil and Patchouli oil to determine the antimicrobial potential of their extracted oils. Method: The active agents in each plant were extracted by steam distillation and by boiling. The antimicrobial activities of the extracts were determined at neat and by two-fold dilutions in well agar diffusion technique using Escherichia coli, Salmonella typhi, Staphylococcus aureus, shigella flexneri, Klebsiella aerogenes and Entero faecalis. Results: All oil extracts possessed antimicrobial activity against most of the bacteria. The clove oil extract showed the highest mean zone of inhibition ranging from 29mm to 35 mm against tested microorganisms, at a concentration of 100 mg/mL. Conclusions: The present finding suggests that the fresh carpel oil of Zanthoxyulum rhetsa Roxb DC, Dried carpel oil of Zanthoxyulum rhetsa Roxb DC, Eucalyptus oil, Clove oil, Palmarose oil and Patchouli oil could be developed as pharmaceutical products.
