Abstract: Rosa laevigata Michx. belongs to Rosaceae family. Polysaccharides,important components of it,were reported to have various physiological activities,such as antioxidation and lowering blood lipids. At this stage,there a lot of extraction methods of the Rosa laevigata Michx. polysaccharides but without generalization,while little innovative research on purification can be seen. Moreover,much research has demonstrated that polysaccharides from Rosa laevigata Michx. have strong physiological activities,but lacking research on mechanisms. This review focused on the research progress on extraction,purification and physiological activities of polysaccharides from Rosa laevigata Michx.,discussed recent advances and made some expectations.
