Two novel anthocyanins, delphinidin 3-O-(6-O-cis-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta-D -glucoside) and petunidin 3-O-(6-O-trans-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta -D-glucoside) , were isolated from the blue flowers of Hyacinthus orientalis cv. Delft Blue. Five known acylated anthocyanins, namely, delphinidin 3-O-(6-O-trans-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-beta-D-gluco side), delphinidin 3-O-(6-O-trans-caffeoyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta-D- glucoside), delphinidin 3-O-(6-O-trans-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta -D-glucoside) , cyanidin 3-O-(6-O-trans-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta -D-glucoside) and pelargonidin 3-O-(6-O-trans-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta -D-glucoside) , were also isolated from these flowers. The complete structure of each compound was unambiguously determined by one- and two-dimensional NMR techniques.
从东方风信子“代尔夫特蓝”品种的蓝色花朵中分离出两种新型花青素，即飞燕草素3 - O -（6 - O -顺式对香豆酰基-β - D -葡萄糖苷）- 5 - O -（6 - O -丙二酰基-β - D -葡萄糖苷）和矮牵牛素3 - O -（6 - O -反式对香豆酰基-β - D -葡萄糖苷）- 5 - O -（6 - O -丙二酰基-β - D -葡萄糖苷）。还从这些花朵中分离出五种已知的酰化花青素，分别是飞燕草素3 - O -（6 - O -反式对香豆酰基-β - D -葡萄糖苷）- 5 - O -（6 - O -β - D -葡萄糖苷）、飞燕草素3 - O -（6 - O -反式咖啡酰基-β - D -葡萄糖苷）- 5 - O -（6 - O -丙二酰基-β - D -葡萄糖苷）、飞燕草素3 - O -（6 - O -反式对香豆酰基-β - D -葡萄糖苷）- 5 - O -（6 - O -丙二酰基-β - D -葡萄糖苷）、矢车菊素3 - O -（6 - O -反式对香豆酰基-β - D -葡萄糖苷）- 5 - O -（6 - O -丙二酰基-β - D -葡萄糖苷）和天竺葵素3 - O -（6 - O -反式对香豆酰基-β - D -葡萄糖苷）- 5 - O -（6 - O -丙二酰基-β - D -葡萄糖苷）。通过一维和二维核磁共振技术明确确定了每种化合物的完整结构。
