Abstract: Purple sweet potato colorant is a natural anthocyanin pigment derived from purple sweet potato storage roots. The concentration of anthocyanins in outer portion of storage roots are higher than that in inner. The biosynthesis of anthocyanins was mainly determined by the genotype of sweet potato, but also affected by the cultural conditions. At present, the pigment from purple sweet potato is extracted by acid solution, the major anthocyanins are cyanidin and peonidin acylated with aromatic acid, such as caffeic acid, ferulic acid and ρ-hydroxybenzoic acid. It is stable to the light and heat, shows functions of antioxidation, antimutagenicity and protection for liver damage. So, it has broad prospects for the application in food, cosmetics and medicine industry.
