Abstract In this study, the essential oil composition of Ferula communis L. subsp. communis and Smyrnium cordifolium collectedfrom Turkey were studied. The qualitative and quantitative essential oil composition were determined and compared with each other. The chemical composition of the essential oils obtained by hydrodistillation from Ferula communis subsp. communis and Smyrnium cordifolium were investigated by GC and GC-MS. The oil yield was determined as 0.2 and 0.3% (v/w) in the both essential oils respectively. Sixty three constituents were comprised the 99.4 % of the total essential oil extracted from the Ferula communis subsp. communis. The predominant compounds of the oil were determined as a-eudesmol (35.5%), 2-naphtalonemethanol (18%), di-epi-a-cedrene (3.5%) and t-muurolol (2.7%). The furanodiene (28%), bicyclogermacrene (19.5%), β-phellandrene (13.5%), cyclohexadecane (10.0%) and 2-pentadecanone (5.0%) were the main compounds identified in the oil of Smyrnium cordifolium, representing 99.2% total oil. The result has been discussed in view of natural products and chemotaxonomical approach in the genera patterns.
