Guaianolides from Cichorium intybus and structure revision of Cichorium sesquiterpene lactones.
The isolation and structure elucidation of a new lactucopicrin derivative from Cichorium intybus is described, together with the revised structures of several sesquiterpene lactones previously isolated from Cichorium species. The known eudesmanolide magnolialide and the known guaianolide ixerisoside D, reported for the first time from the plant material, along with the previously known chicory sesquiterpene lactones have been also isolated and identified.
