UV visible spectrum of cyanidin 3-O-glucoside.
Chrysanthemin is an anthocyanin. It is the 3-glucoside of cyanidin.
Natural occurrences
Chrysanthemin can be found in the roselle plant (Hibiscus sabdariffa, Malvaceae), different Japanese angiosperms,[1] Rhaponticum (Asteraceae),[2] The fruits of the smooth arrowwood (Viburnum dentatum, Caprifoliaceae) appear blue. One of the major pigments is cyanidin 3-glucoside, but the total mixture is very complex.[3]
In food
Chrysanthemin has been detected in blackcurrant pomace, in European elderberry,[4] in red raspberries, in victoria plum,[5] in peach,[6] lychee and açaí.[7] It is the major anthocyanin in purple corn (Zea mays). Purple corn is approved in Japan and listed in the "Existing Food Additive List" as purple corn color.[8]
Biosynthesis
The biosynthesis of cyanidin 3-O-glucoside in Escherichia coli was demonstrated by mean of metabolic genetic engineering.[9]
In Arabidopsis thaliana, a glycosyltransferase, UGT79B1, is involved in the anthocyanin biosynthetic pathway. UGT79B1 protein converts cyanidin 3-O-glucoside to cyanidin 3-O-xylosyl(1→2)glucoside.[10]
