Abstract: Ziziphus jujuba is a commonly used medicinal and edible plant in China. Ziziphus jujuba polysaccharide is one of the main active component of Ziziphus jujuba, and has been confirmed by pharmacological studies with a variety of biological activities. The research on the structure of Ziziphus jujuba polysaccharide is mostly focused on modification method, monosaccharide constitutes, molecular weight and glycosidic bond type. Extensive studies have shown that Ziziphus jujuba polysaccharide exert multiple biological activities, such as antioxidant, hepatoprotective, hypoglycemic, lipid-lowering, bacterial abundance regulation, immune regulation, anti-cancer and anticoagulant. Ziziphus jujuba polysaccharide can be used in anti-oxidation film, anti-aging, hypoglycemic, sugar replacement, lipid-lowering products, bacteriostatic agent, immunomodulators, anti-cancer nutrition food and other products. Based on these findings, this article summarizes and prospects, in order to provide a theoretical basis for further explore the structure of Ziziphus jujuba polysaccharides, standardize the preparation and extraction process of Ziziphus jujuba polysaccharides, clarify the biological activity mechanism of Ziziphus jujuba polysaccharides, and increase the diversity of Ziziphus jujuba polysaccharide products.
