Volatile Oils of Ferulago phialocarpa Rech. f. et H. Reidl. and Leutea elbursensis Mozaffarian from Iran

Abstract The water distilled oils from the aerial parts of Ferulago phialocarpa Rech. f. et H. Riedl. and the aerial parts of Leutea elbursensis Mozaffarian (Umbelliferae), which are endemic to Iran, were analyzed by GC/MS. α-Pinene (40.9%), α-phellandrene (14.2%) and β-phellandrene (9.6%) were the main components among the 26 constituents characterized in the oil of Ferulago phialocarpa, representing 93.8% of the total components detected. Thirty-three compounds were identified in the oil of L. albursensis, representing 98.0% of the total oil, with α-pinene (37.3%) and β-pinene (36.1%) as main constituents. Both oils were richer in monoterpene, rather than sesquiterpene, hydrocarbons.
