Abstract:Pueraria lobata exhibits a wide range of pharmacological activities and holds significant potential for development and utilization. Pueraria lobata is rich in various bioactive compounds，including polysaccharides，flavonoids，saponins，organic acids，alkaloids，vitamins，and phenolic compounds. In recent years，polysaccharides have been identified as one of the main active components in Pueraria lobata，and extensive research has been conducted to explore their properties. These studies have revealed that Pueraria lobata polysaccharides possess multiple biological activities，such as immunomodulation，hypoglycemic effects，and antioxidant properties. In this study，recent research progress on Pueraria lobata polysaccharides was reviewed，focusing on their extraction，isolation，structural characteristics，and biological activities，and a reference was expected to be provided for the comprehensive utilization of Pueraria lobata polysaccharides.
