The essential oil obtained by hydrodistillation from dried aerial parts of Torilis japonica was analyzed by gas chromatography/mass spectrometry and 31 compounds were identified. The oil was dominated by β-eudesmene (22.87 %), α-selinene (12.94 %), eudesm-7(11)-en-4-ol (10.42 %) and β-elemene (8.22 %), which were all sesquiterpenes. The antibacterial activity of the oil was tested against the food spoilage bacteria, including Staphylococcus aureus , Bacillus subtilis , Listeria monocytogenes , Escherichia coli , Shigella dysenteriae , Bibrio parahemolyticus and Salmonella typhimurium . The results showed that the extracted oil was effective against S. typhimurium , B. subtilis and L. monocytogenes using the agar disk diffusion method and B. subtilis was the most sensitive strain with the minimum inhibitory concentration of 0.16 mg/ml by the broth microdilution bioassay.
