Research Progress on Structure, Biological Activity and Product of Ziziphus jujuba Polysaccharide

Ziziphus jujuba is a commonly used medicinal and edible plant in China. Ziziphus jujuba polysaccharide, one of the main active component of Ziziphus jujuba, has been confirmed by pharmacological studies that it has 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 further explore the structure of Ziziphus jujuba polysaccharide in the future, standardize its preparation and extraction process, clarify the mechanism mechanism, increase product diversity, and provide a theoretical basis for the follow-up research, development and application of Ziziphus jujuba polysaccharide.
