It is a group of flint maize varieties ( Z. Purple corn ( Zea mays L.) is an annual grass that belongs to the family of Poaceae. The results of in vitro and in vivo studies of the biological properties of purple corn could lead to the development of different health-promoting products in the near future. Purple corn color extracts possess a variety of biological properties, including antioxidant, anti-inflammatory, anticancer, anti-diabetic, anti-obesity, etc. This review emphasized recent updates regarding the in vitro and in vivo biological properties of extracts and compounds from purple corn. Purple corn is rich in various health-promoting compounds, mainly anthocyanins such as cyanidin-3- O-glucoside, perlagonidin-3- O-glucoside, peonidin 3- O-glucoside, and their malonylated forms. The color pigments are chiefly found in the pericarp or kernels, in addition to corn cobs. Anthocyanin is the water-soluble pigment found in various fruits and vegetables. ![]() The whole plant of purple corn has a high amount of anthocyanin content.
