Chemical Composition of the Essential Oil from the Aerial Parts of Ferulago angulata (Schlecht.) Boiss. from Northeast Iran

The essential oil obtained by hydrodistillation of the aerial parts of Ferulago angulata (Schlecht.) Boiss. (Umbelliferae), growing wild in Khorasan province in Iran, were analyzed by GC and GC-MS. Twenty compounds representing 98.1 % of the aerial parts oil of Ferulago angulata were identified, of which alpha-phellandrene (24.2%), beta-phellandrene (14.9%),(alpha-pinene (14.7 %)and p-cymene (10.3 %)were the major ones, other major component of the oil were delta-3-carene (6.7 %) and (Z)-beta-ocimene (5.8 %). Aerial parts oil of the plant consist of monoterpenes (97.6 %) and one oxygen containing sesquiterpene (0.5 %). Monoterpene hydrocarbons (90.8 %) were the major constituents.
