Cabulicus) essential oils and antimicrobial properties from Iran. The chemical composition of the essential oils was determined by gas chromatography coupled to a mass spectrometer. An agar well diffusion method evaluated the antimicrobial effect of the essential oils of the tested species against 3 Escherichia coli, Staphylococcus aureus, and Bacillus atrophaeus. In the essential oils of L. Cabulicus, 30 compounds which constituted 86.65% of the essential oils have been identified, the main constituents of α-pinene (36.01%), β-myrcene (10.21%), Germacrene D (6.03%), Limonene (4.75%) and cis-verbenone (4.73%) were the main components of the essential oils. 21 compounds were identified in the essential oils of L. Aucheri which made up 84.28% of the essential oils. α-pinene (24.74%), β-myrcene (12.85%), p-cymene (12.10%), Germacrene D (8.85%), Limonene (6.15%) and p-cymene-4-oil (5.23%) constituted the main components of this essential oil. Also, the results of microbial tests against 3 pathogenic bacteria showed significant effects on Staphylococcus aureus and Bacillus atrophaeus, and no effect was observed on Escherichia coli.  UR - https://www.echemcom.com/article_143649.html L1 - https://www.echemcom.com/article_143649_53a1eb9f2360681fdb3122705b5f254b.pdf ER -
