Chrysanthemin is an anthocyanin. It is the 3-glucoside of cyanidin.
Natural occurrences
Chrysanthemin can be found in the roselle plant (Hibiscus sabdariffa), different Japanese angiosperms,[1]Rhaponticum,[2] The fruits of the smooth arrowwood (Viburnum dentatum) appear blue. One of he major pigments is cyanidin 3-glucoside, but the total mixture is very complex.[3]
in food
It has been detected in blackcurrant pomace, victoria plum,[4]peach[5] and açaí.[6]
Biosynthesis
The biosynthesis of cyanidin 3-O-glucoside in Escherichia coli was demonstrated by mean of metabolic genetic engineering.[7]
