Abstract:

Chinese yam(Rhizoma Dioscorea) was widely used as food and medicinal plants,among its composition,the polysaccharide(RDP) was considered an important active substances.This manuscript reviewed the research progress of RDP extraction and separation,purification,chemical structure analysis and physiological activity.The results presented in this manuscript may provided a novel clue for development of new extraction process,investigation of structure-activity relationship and elucidation of mechanism.
