Research Progress on Antioxidant Activity of Natural Plant Polysaccharides
[Objective]To review the antioxidant mechanism,antioxidant research methods in vitro and in vivo,and the relationship between polysaccharide structure and antioxidant activity,so as to provide scientific basis for further research and utilization of polysac-charides.[Method]The relevant literatures on antioxidant effects of natural plant polysaccharides were systematically reviewed in domestic and foreign databases,and the relevant information was summarized.[Result]Natural plant polysaccharides exert antioxidant effects through a variety of mechanisms,and have good antioxidant activities in vitro and in vivo,which has an important relationship with its structure.[Conclusion]Natural plant polysaccharides as natural antioxidants have broad application prospects.
