"Chemical composition and antimicrobial activity of the essential oil of Ferulago Bernardii Tomk. and M. Pimen"

The chemical composition of the essential oil of the aerial parts of Ferulago Bernardii from Iran was analysed by GC and GC/MS. Sixty constituents were found representing 87.9% of the oil. The main constituents of the essential oil were 2,4,5-trimethyl-benzaldehyde (21.2%), α-pinene (17.0%),spathulenol (5.0%), cis-chrysanthenyl acetate (4.4%) and caryophyllene oxide (3.2%). Antimicrobial activity of the essential oil of Ferulago Bernardii by the broth dilution method in comparison with Gentamycin and Fluconazole as standard showed weak activity against Staphylococcus aureus, Bacilus subtilis, Escherichia coli, Candida albicans and Aspergillus niger.
