In order to improve the extraction rate of Polygonatum odoratum polysaccharide, the extraction process of Polygonatum odoratum polysaccharide with deep eutectic solvents was optimized by response surface methodology. The antioxidant activity of Polygonatum odoratum polysaccharide extracted by deep eutectic solvents (DPoP) was evaluated by DPPH radical scavenging rate, ABTS cationic radical scavenging rate and ORAC methods, and the inhibitory ability of DPoP on the formation of advanced glycation end products (AGES) in non-enzymatic glycation sy...
