Abstract

Abstract The composition of the essential oils from three Umbelliferae species of Iran—Dorema aucheri Boiss., which is endemic to Iran, Seseli libanotis (L.) W. D. Koch var. armeniacum Bordz. and Conium maculatum L.—obtained by hydrodistillation were analyzed by GC and GC[sol ]MS. α ‐Eudesmol (31.2%) and δ ‐cadinene (10.9%) were the main components among the 35 constituents characterized in Dorema aucheri, representing 89.2% of the total components detected. Twenty‐five compound were identified in the oil of Seseli libanotis, repesenting 90.6% of the total oil with acorenone (35.5%) as the major constituents. The oil of Conium maculatum was characterized by higher amount of germacrene D (46.1%), β ‐caryophyllene (15.3%) and ( E , E )‐ α ‐farnesene (10.1%) among the 17 components comprising 91.0% of the total oil detected. All oils were richer in sesquiterpenes than monoterpenes. Copyright © 2006 John Wiley &amp; Sons, Ltd.
