A new acylated anthocyanin was isolated from the violet-blue flowers of Pharbitis nil as a minor anthocyanin. The structure of this pigment was determined to be cyanidin 3-O-(2-O-(beta-D-glucopyranosyl)-6-O-(trans-4-O-(beta-D- glucopyranosyl)caffeyl)-beta-D-glucopyranosyl)-5-O-(beta-D-glucopyranosi de) based on spectroscopic methods.
从牵牛的紫蓝色花朵中分离出一种新的酰化花青素，它是一种次要的花青素。基于光谱方法，确定该色素的结构为矢车菊素3 - O -（2 - O -（β - D - 吡喃葡萄糖基）- 6 - O -（反式 - 4 - O -（β - D - 吡喃葡萄糖基）咖啡酰基）- β - D - 吡喃葡萄糖基）- 5 - O -（β - D - 吡喃葡萄糖苷）。
