essential oil composition of ferula assa-foetida l. fruits from western iran

chemical composition of the essential oil of the fruit of ferula assafoetida l. obtained by steam distillation solvent extraction methodhas been studied by gc/ms for the first time. fifty-four components, comprising 96.9% of the total oil, were identified.epi-α-cadinol (23.15 %), germacrene b (10.98 %), α-gurjunene (6.18 %), (z)-1-propenyl secbutyl disulfide (5.89 %), 5-epi-7-epi-α-eudesmol (4.89 %), -cadinene (4.78 %), -cadinene (3.36 %) and germacrene d (3.09 %) were found to be the major constituents of the oil. the oil of the fruit of f. assafoetidaconsisted of ten monoterpene hydrocarbons (6.14%), twenty-six sesquiterpene hydrocarbons (43.48%), nine oxygenated sesquiterpenes (37.77%), one oxygenated hydrocarbon (0.35%), and nine volatile sulfides (11.18%).
