The objective of the present study was to determine the composition of fatty acids in leaves of nine chicory cultivars (Cichorium intybus L.). The growing practice followed the traditional forcing method of developed roots in a peat to obtain new etiolated vegetative apical buds, known as chicons. The fatty acid content was determined by the extraction of fatty acid methyl esters and analysis by means of gas chromatography. The analysis revealed the following ratios of C16:0, C18:0, C18:1, C18:2 and C18:3 of individual fatty acids. The total fatty acid content in forced chicory leaves ranged from 104 to 644 mg/100 g fresh weight. The highest relative content (64%) is presented by ?-linolenic acid, followed by linoleic (44%) and palmitic (21%). An n-6/n-3 polyunsaturated fatty acids ratio of studied forced chicory is below 1.4 and thus, in accordance with the recommended dietary ratio that is close to 1.

Ultrasound Assisted

A method for simultaneous determination of 16 free fatty acids (FFAs) in serum is described. The method involves conversion of FFAs to fatty acid methyl esters (FAMEs) using the heat of ultrasonic waves followed by gas chromatography and mass spectrometry (GC–MS) analysis. Optimum levels of the variables affecting the yield of FAMEs were investigated. The results indicate that the optimal levels are 55 °C, 60 W, 10% H2SO4/CH3OH, and 50 min. Recoveries ranged from 85.32% to 112.11%, with a detection limit ranging from 0.03 to 0.08 μg mL–1. The linearity, using the linear correlation coefficient, was higher than 0.9914.
