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

摘要

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 beta-caryophyl-lene(22.3%),myrcene(21.7%)and beta-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.
