红色/淡紫色康乃馨品种“Kortina Chanel”和“Purple托雷斯”的花含有独特的大环花青素色素，即苹果酰化矢车菊素3，5-二葡萄糖苷，其中苹果酰基与两种糖连接。天然花色素苷容易进行开环以产生矢车菊素3-O-（6-O-苹果酰基葡萄糖苷）-5-O-葡萄糖苷。这种不稳定性被认为是由于苹果酰基糖苷间桥的固有不稳定性。本文报道了天然花色苷及其开环产物的结构鉴定。(C)1998爱思唯尔科技有限公司版权所有。
Flowers 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. (C) 1998 Elsevier Science Ltd. All rights reserved.
