Antimicrobial activities of Ferulago essential oils

Essential oils from Ferulago asparagifolia Boiss., F. galbanifera (Miller) W. Koch, F. humilis Boiss. (Endemic), F. trachycarpa Boiss. growing in Turk ey were evaluated against 15 microorganisms for their antifungal and antiba cterial activity using an agar tube dilution and microdilution broth suscep tibility assay, respectively. The essential oil compositions were investiga ted by GC/MS. Inhibitory effects against Escherichia coli, Enterobacter aer ogenes, Candida albicans, Gaeumannomyces graminis var. tritici, Sclerotium rolfsii and Fusarium moniliforme were remarkable. Results are discussed in comparison with the chemical composition of the essential oils.
