Abstract
Five new ternatins 1−5 have been isolated from Clitoria ternatea flowers, and the structures have been determined by chemical and spectroscopic methods as delphinidin 3-malonylG having 3‘-GCG-5‘-GCG, 3‘-GCG-5‘-GC, 3‘-GCGCG-5‘-GC, 3‘-GCGC-5‘-GCG, and 3‘-GCGC-5‘-GC side chains, respectively, in which G is d-glucose and C is p-coumaric acid. Pigment 1 had symmetric 3‘,5‘-side chains. Compounds 3 and 4 are structural isomers. These ternatins were shown to form an intramolecular stacking between the aglycon ring and the 3‘,5‘-side chains in solution.Keywords
