Cyanidin-3,5-O-diglucoside

Cyanidin-3,5-"O"-diglucoside, also known as cyanin, is an anthocyanin. It is the 3,5-"O"-diglucoside of cyanidin.
Natural occurrences.
Cyanin can be found in species of the genus "Rhaponticum" (Asteraceae).
In food.
Cyanin can be found in red wine as well as pomegranate juice according to a study done by Graça Miguel, Susana Dandlen, Dulce Antunes, Alcinda Neves, and Denise Martins in the winter of 2004. Pomegranate juice extracted through centrifugal seed separation has higher amounts of cyanidin-3,5-"O"-diglucoside than juice extracted by squeezing fruit halves with an electric lemon squeezer.
