Fatty acid composition of fl owers of Crepis foetida subsp. rhoeadifolia from Turkey

Abstract

This study aims to describe the fatty acid composition of flowers of Crepis foetida subsp. rhoeadifolia. In order to
define qualitative and quantitative profile, fatty acids were derived to their methyl esters, and then these were
analyzed by gas chromatography - flame ionization detector. 20 fatty acids were determined in the oil. Palmitic
(C 16:0), myristic (C 14:0), and linoleic acids (18:2 ω6) were found to be major fatty acids. Total saturated
fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids (PUFA) were 62.67%, 17.54%, and
19.79%, respectively. Also, total essential fatty acids (EFA) were determined ad 14.48%. Therefore, the oil can
be considered as a new source of PUFA, especially EFA.
