Tetra-acylated cyanidin 3-sophoroside-5-glucosides from the flowers of Iberis umbellata L. (Cruciferae)

Eleven acylated cyanidin 3-sophoroside-5-glucosides (pigments 1-11) were isolated from the flowers of Iberis umbellata cultivars (Cruciferae), and their structures were elucidated by chemical and spectroscopic methods.
