Endive (Cichorium endivia, L.) originates from South Asia and is one of the most important European winter salads, but knowledge about its constituents is rather scarce, with studies only on a few nonvolatile compounds and no previous investigation on volatiles formed after tissue disruption. Concentrates of endive volatiles were obtained by standard controlled solvent extraction (pentane-dichloromethane, 2:1) of the blended leaves followed by silica gel LC preseparation using a pentane-diethyl ether gradient. Analysis by capillary gas chromatography and coupled capillary gas chromatography-mass spectrometry led to identification of 119 volatiles first described as endive constituents. Qualitatively and quantitatively enzyme-catalyzed lipid cleavage products were predominant; C6 aldehydes comprised about 70% of the total amount of volatiles.
