The major anthocyanins of radishes are pelargonidin-3-sophoroside-5-glucoside acetylated with malonic acid and either ferulic or p-coumaric acid. Cinnamic acid acylation site for radish anthocyanins was determined to be at position 6 of glucose-1 of the sophorose substituents by one- and twodimensional 1HNMR-13CNMR[46]. Also 7-glucoside-pelargonidin has been identified in R. sativus[47].
This compound was stable at 60˚C and under light, may be used as a food colorant[48].
