ResumoA survey of 31 species from 28 genera in the Compositae showed the presence of zwitterionic anthocyanins in petals or stems of 27 species. Detailed investigations, including the use of FAB-MS, showed that mono- and dimalonated esters of pelargonin and cyanin occurred in Dahlia variabilis cultivars. The corresponding delphin mono- and dimalonates occur in blue flowers Cichorium intybus. A cyanidin 3-dimalonylglucoside was identified in stems of Coleostephus myconis while pelargonidin 3-(6″-malonylg]ucoside) was found in Callistephus petals. A further malonated cyanidin derivative in flowers of Helenium cv. Bruno was found to be the 3-glucuronosylglucoside; this is the first report of an anthocyanin with glucuronic acid. Overall, the results confirm that malonated anthocyanins are widespread in the family and that many pigments previously reported in the Compositae as being unacylated probably contain these labile organic acid attachments.
