Research Progress of Lycium barbarum Polysaccharides
Lycium barbarum L.is a traditional Chinese functional food used in both medicine and food.Lycium barbarum polysaccharide is a complex glycoprotein conjugate,which has the functions of immune regulation and lowering blood sugar,and is one of the important pharmacodynamic substances of Lycium barbarum.In this paper,the existing researches on extraction,purification and separation of Lycium barbarum polysaccharide were reviewed comprehensively,and various methods were compared to clarify their advantages and disadvantages,including traditional extraction and separation methods and various new technologies and methods,such as subcritical water extraction method,high voltage pulsed electric field extraction technology,high-speed shear technology,repeated freeze-thaw method and so on.In this paper,the existing new methods and technologies were summarized to provide reference for further research and development of Lycium barbarum polysaccharide.
