Chemical composition of essential oil of Ferulago macrocarpa (Fenzl) Boiss. fruits

Water-distilled essential oil of Ferulago macrocarpa (Umbelliferae) fruits was analyzed using GC-MS for the first time. Forty-two components comprising 99.5% of the total oil were identified, of which bornyl acetate (40.8%), 2,3,6-trimethyl benzaldehyde (7.2%), ?-selinene (5.5%), 1,10-di-epi-cubenol (5.1%), germacrene D (3.5%), B-phellandrene (3.5%) and ?-pinene (3.4%) were found to be the major components. The oil of F. macrocarpa fruits consisted of 15 monoterpene hydrocarbons (21.4%), 6 oxygenated monoterpenes (42.2%), 17 sesquiterpene hydrocarbons (22.4%) and one oxygenated sesquiterpene (5.1%). Three benzenoid derivatives also comprised 8.4% of the oil. Monoterpenes and sesquiterpenes comprised 63.6% and 27.5% of the F. macrocarpa fruits essential oil respectively; however, bornyl acetate (40.8%) was identified as the most abundant component of the oil.
