Abstract:Blueberries contain high levels of biologically active small molecules.The most prevalent of these small molecules are the anthocyanins.Anthocyanins possess many beneficial physiological functions，making them a high value target for development and utilization.To provide insights into the physiological functional characteristics of blueberry anthocyanins，this paper reviewed research progress into species specific blueberry anthocyanin structures，their absorption and metabolism，and functional properites，including antioxidant，hypoglycemic，lipid lowering，anti-inflammatory，and bacteriostatic effects，and intestinal flora regulation，providing a basis for further research，and for development and utilization of blueberry anthocyanins.
