AbstractFlowers of the red/mauve carnation cultivars 'Kortina Chanel' and 'Purple Torres' contain a unique macrocyclic anthocyanin pigment, a malylated cyanidin 3,5-diglucoside in which the malyl group is linked to both sugars. The native anthocyanin readily undergoes ring opening to yield cyanidin 3-O- (6-O-malyl glucoside)-5-O-glucoside. This lability was found to be due to the inherent instability of the malyl interglycosidic bridge. In this paper we report the structure elucidation of the native anthocyanin; and the ring opened product.
