Volatile Constituents of Three Umbelliferae Herbs:<i>Azilia eryngioedes</i>(Pau) Hedge et Lamond,<i>Laser trilobum</i>(L.) Borkh. and<i>Falcaria falcarioides</i>(Bornm. et Wolff) Growing Wild in Iran

Abstract

Abstract The composition of the essential oils from three Umbelliferae species of Iran—Azilia eryngioedes (Pau) Hedge et Lamond, which is endemic to Iran, Laser trilobum (L.) Borkh. and Falcaria falcarioides (Bornm. et Wolff) Wolff—obtained by hydrodistillation were analyzed by GC/MS. Bornyl acetate (40.9%) was the main component among the 26 constituents characterized in the oil of A. eryngioedes, representing 93.8% of the total components detected. Eighteen compounds were identified in the oil of L. trilobum, representing 85.2% of the total oil, with β-caryophyl- lene (22.3%), myrcene (21.7%) and β-sesquiphellandrene (19.2%) as the major constituents. The oil of F. falcarioides was characterized by a higher amount of germacrene B (67.9%) among the 24 components comprising 97.6% of the total oil detected.
