Natural occurrences

Chrysanthemin can be found in the roselle plant (Hibiscus sabdariffa, Malvaceae), different Japanese angiosperms,[2] Rhaponticum (Asteraceae),[3] 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.[4]

In food

Chrysanthemin has been detected in blackcurrant pomace, in European elderberry,[5] in red raspberries, in soybean seed coats,[6] in Victoria plum,[7] in peach,[8] lychee and açaí.[9] It is found in red oranges[10] and black rice.[11]

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.[12]

Biosynthesis

The biosynthesis of cyanidin 3-O-glucoside in Escherichia coli was demonstrated by means of genetic engineering.[13]

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.[14]
