title: Anthocyanins from flowers of Cichorium intybus.
abstract: From the blue perianth segments of Cichorium intybus we isolated four anthocyanins. The pigments were identified as delphinidin 3,5-di-O-(6-O-malonyl-beta-D-glucoside) and delphinidin 3-O-(6-O-malonyl-beta-D-glucoside)-5-O-beta-D-glucoside and the known compounds were delphinidin 3-O-beta-D-glucoside-5-O-(6-O-malonyl-beta-D-glucoside) and delphinidin 3,5-di-O-beta-D-glucoside. In addition 3-O-p-coumaroyl quinic acid has been identified.
