| "Five known and one new sesquiterpene lactones were isolated from fresh chicory roots (Cichorium intybus). The new compound 11(S),13-dihydrolactucopicrin was identified by UV, 1H NMR, 13C NMR, and mass spectroscopy. The extraction procedure and HPLC analysis of sesquiterpene lactones in chicory were improved. The bitterness detection thresholds of all compounds were individually determined by triangle testing. 11(S),13-Dihydrolactucopicrin was extremely bitter, with a treshold level of 0.02ppm. Four other lactones showed treshold values similar to that of quinine hydrochloride." \\ | "Five known and one new sesquiterpene lactones were isolated from fresh chicory roots (Cichorium intybus).

| "The leaves and especially the roots of chicory (Cichorium intybus L.) contain high concentrations of bitter sesquiterpene lactones such as the guianolides lactupicrin, lactucin, and 8-deoxylactucin. Eudesmanolides and germacranolides are present in smaller amounts. Their postulated biosynthesis through the mevalonate-farnesyl diphosphate-germacradiene pathway has now been confirmed by the isolation of a (+)-germacrene A synthase from chicory roots." \\ | "The leaves and especially the roots of chicory (Cichorium intybus L.) contain high concentrations of bitter sesquiterpene lactones such as the guianolides lactupicrin, lactucin, and 8-deoxylactucin.

| Levels of sesquiterpene lactones (SL) in fresh-cut chicory (Witloof Chicory, C.intybus var.foliosum) are reduced by washing. Applied warm water significantly reduced the contents and bitterness. "SL profiles changed substantially in all samples during storage, revealing lactucopicrin to be the major SL directly after processing, whereas 11(S),13-dihydrolactucin prevailed at the end of storage." \\ | Levels of sesquiterpene lactones (SL) in fresh-cut chicory (Witloof Chicory, C.intybus var.foliosum) are reduced by washing.

Many volatile components were identified in SDE (92) and DHS (64) extracts. Many pyrazines and N-furfurylpyrroles (N-furfurylpyrrole, N-furfuryl-2-formylpyrrole, and N-furfuryl-2-acetylpyrrole) were identified for the first time in roasted chicory. Aroma extract dilution analysis showed that those extracts from SDE and DHS were similar with respect to predominant aroma-active components. 2-Ethyl-3,5-dimethylpyrazine, 2,3-butanedione, 1-octen-3-one, 3-methylbutanal, and one unknown compound with a chicory- and burnt sugar-like note were the most intense aroma-active components found in roasted chicory." \\ | "Volatiles were isolated from roasted chicory by simultaneous steam distillation-solvent extraction (SDE) and dynamic headspace sampling (DHS).
