Angelica sinensis is a frequently used traditional Chinese medicine with traditional medicinal and food ingredients,and A. sinensis polysaccharide is one of its effective components,which has a wide range of pharmacological effects such as blood tonicity,anti-inflammation,and antioxidant.With the continuous development of extraction and purification of natural polysaccharides from traditional Chinese medicine and structural analysis technologies,the number of A. sinensis polysaccharides,their composition and chemical structure have been constantly improved,which reflects the characteristics of biodegrad ability,lower difficulty of structural modification,natural liver targeted and so on,and it has a brilliant prospect for drug carriers.In this paper,the new developments in the structural analysis,extraction and purification,and expanded application of A. sinensis polysaccharides are summarised to provide reference for the further development and utilisation of A. sinensis polysaccharides.
