Anthocyanidin is a natural flavonoid pigment commonly found in all kinds of colored plants,such as fruits,vegetables and so on.Compared with blueberry,black grape and other plant resources rich in anthocyanidin,purple corn has the advantages of high yield,low price and high content of anthocyanidin,making it a good source of anthocyanidin with certain research value.Purple corn anthocyanidin has many biological activities,such as anti-oxidation,anti-mutagenesis,anti-tumor,pre-prevention of obesity and so on,and is therefore widely used in food,medicine,cosmetics and other fields.In this paper,the extraction methods,purification,biological activity and stability of purple corn anthocyanidin and other anthocyanidin were reviewed in order to provide a basis for the comprehensive development and utilization of purple corn anthocyanidin.
