The incidence of diabetes has been increasing year by year. Diabetes treatments mainly with Western medicines can cause side effects, which will stimulate people to turn their attention to natural bioactive substances. As a group of safe, low-toxic natural substances, polysaccharides have many biological activities such as hypoglycemic activity and thus have great development potential. In this paper, the relationship between the hypoglycemic activity and structure of polysaccharides is reviewed with respect to molecular mass, monosaccharide composition, glycosidic bonds, advanced structures and groups, and the mechanism of the hypoglycemic action of polysaccharides is summarized. Furthermore, problems existing in this field of research and future research directions are discussed. %U https://www.spkx.net.cn/EN/10.7506/spkx1002-6630-20200818-244
