Myrtillin is an anthocyanin. It is the 3-glucoside of delphinidin. It can be found in all green plants, most abundantly in black beans, blackcurrant, blueberry, huckleberry, bilberry leaves^[1]^[2] and in various myrtles, roselle plants, and Centella asiatica plant.^{[citation needed]} It is also present in yeast and oatmeal.^{[citation needed]} The sumac fruit's pericarp owes its dark red colour to anthocyanin pigments, of which chrysanthemin, myrtillin and delphinidin have yet been identified.^[3]^{[unreliable source?]}

The various colors, such as red, mauve, purple, violet, and blue in Hydrangea macrophylla are developed from myrtillin complexes with metal ions called metalloanthocyanins.^[4]

Metabolism

The enzyme anthocyanin 3-O-glucoside 6''-O-hydroxycinnamoyltransferase produces delphinidin 3-(6-p-coumaroyl)glucoside from myrtillin and p-coumaroyl-CoA in the anthocyanin biosynthesis pathway.^[5]
