UV visible spectrum of cyanidin 3-O-glucoside

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 soybean seed coats,^[5] in Victoria plum,^[6] in peach,^[7] lychee and açaí.^[8] It is found in red oranges^[9] and black rice.^[10]

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.^[11]

Biosynthesis

The biosynthesis of cyanidin 3-O-glucoside in Escherichia coli was demonstrated by means of genetic engineering.^[12]

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.^[13]
