More than 150 anthocyanins acylated with -coumaric acid have been reported. Among these, most of the 132 anthocyanins, which have been assigned with a complete structure (Appendix A), have the p-coumaryl unit(s) in glucose 6-position(s) within a glycosidic moiety linked to the 3-position of the aglycone. In anthocyanins from the genera Eustoma and... 

Zimmerman and Sneden [14] isolated two glycosidic, aromatic esters, or vanacosides. Vanacosides A (28) and B (29) were purified as white amorphous solids from Polygonum species of plants. The vanacosides have p-coumaryl esters at the 1, 3, and 6 positions of sucrose, and a feruloyl ester at the 6 carbon of glucose.
