| Abstract | ||
| Essential oils of cinnamon (Cinnamomum sp.) and frankincense (Boswellia sp. ) have been investigated for their antibacterial activity against six bacterial species including Escherichia coli , Staphylococcus aureus , Pseudomonas aeruginosa , Brucella sp., Klebsiella pneumoniae,and , Proteus sp. .The minimum inhibitory concentration (MIC) of these essential oils were determined using an agar dilution method .MICs of Cinnamomum sp., and Boswellia sp. essential oils ranged from 64-128 µg/ml and 2-80 mg/ml respectively .GC-MS technique was used for constetuent analysis of these oils. The composition of Cinnamomum sp. oil was dominated by cinnamaldehyde (41.62 %),acetic acid,octyl ester (13.58 %) , eugenol (7.1 % ) , coumarin(4.04 %) ,pregnane-11,20dione,3,17-dihydroxy (3.46 % ),and 1-octanol(2.64 % ). The main constituents of Boswellia sp. oil was acetic acid octyl.ester(49.46 % ),1-octanol (15.37 % ),1,6-octadien-3-ol,3,7-dimethyl (6.64 % ),acetic acid trimethyl-bicyclo,hept-2-yl ester (2.28 % ),and propane,1-bromo (1.1 % ). | ||
