Composition of Essential Oil in Sweet Fennel(Foeniculum vulgare Mill. var. dulce) Lines Originated from Turkey

Abstract

This study was carried out to investigate the content and chemical composition of essential oil in 20 sweet fennel lines originated from Turkey. The water-distilled essential oil from dried fruits was analyzed by GC-MS. The essential oil ratios among lines ranged from 1.30 to 4.44 %. The first five components with the highest values in the contents of the essential oil of lines accounted for more than average 98 % of the oil. α-Pinene (0.4 %), myrcene (0.15 %), 3,7-dimethyl-1,3,6- octatriene (0.64 %) and p-anisaldehyde (0.95 %) were found below 1 % regarding average values. trans-Anethole (79.18- 88.17 %), estragole (4.59-6.34 %), limonene (2.18-7.12 %) and α-fenchone (0.97-7.03 %) were found as main constituents.
