Chrysanthemin is an anthocyanin. It is the 3-glucoside of cyanidin. It has been detected in blackcurrant pomace, roselle plant, Japanaese angiosperm, Rhaponticum, victoria plum, and açaí. The biosynthesis of cyanidin 3-O-glucoside in Escherichia coli was demonstrated by mean of metabolic genetic engineering.
