fennel.jpg.size.xxlarge.letterboxFennel (Foeniculum vulgare Mill.), is a small genus of annual, biennial or perennial herbs and aromatic plant belonging to the family Apiaceae. The aim of this study was to identify of the chemical components of fennel cultivated in Iran climatic conditions. The seeds of F. vulgare were collected from three ecotypes (Kermanshah, Hamadan and Shahrekord) province in Iran, during 2014. The essential oil was extracted by a Clevenger approach and analyzed using GC/MS. In total, 28, 30 and 24 compounds were identified in seeds of fennel in Kermanshah, Hamadan and Shahrekord province, respectively. The major components in Kermanshah were; trans-anethole (63.21%), fenchone (9.2%), linalool (7.12%), p-cymene (4.13%), limonene (3.17%) and methyl chavicol (3.14%). The major components in Hamadan were; trans-anethole (70.2%), p-cymene (5.4%), linalool (5.41%), fenchone (4.6%) and methyl chavicol (4.21%). The major components in Shahrekord were; trans-anethole (61.5%), fenchone (11.5%), methyl chavicol (7.31%), limonene (6.7%), linalool (6.16%) and p-cymene (3.46%). The differences in the quantity or quality of the oils composition of the present and previous studies may be because of the chemotypes, phenological stage, drying conditions, mode of distillation and geographic and climatic factors.
