The molecule is a sesquiterpene lactone obtained by formal condensation of one of the carboxy groups of oxalic acid with the 15-hydroxy group of 11beta,13-dihydrolactucopicrin. Found in chicory. It has a role as a plant metabolite. It is an azulenofuran, a cyclic terpene ketone, an enone, an oxo monocarboxylic acid, a member of phenols and a sesquiterpene lactone. It derives from a 4-hydroxyphenylacetic acid, a lactucin and an oxalic acid.
