- Abstract：Objective To study the quality difference of Rhizoma Polygonatum from different habitats.Methods The total sugar content of Polygonatum sibiricum from different habitats was determined by ultraviolet spectrophotometry. The crude polysaccharide and polysaccharide content of Polygonatum sibiricum from different habitats were calculated by alcohol precipitation combined with protein removal. The functional groups of polysaccharide in Polygonatum sibiricum from different habitats were compared by infrared spectroscopy. The antioxidant capacity of polygonatum sibiricum polysaccharide from different habitats was evaluated by DPPH clearance rate. Results Polysaccharides from Yunnan and Hebei were higher than those from Hunan and Hubei. The infrared structure of polygonatum polysaccharides from Hunan and Hubei were different, and the DPPH clearance rate of polysaccharides from Guizhou was the strongest. Conclusion The polysaccharide and antioxidant capacity of Rhizoma Polygonatum are different due to different growth environments, which provides a reference for the selection of high-quality provenance of Rhizoma Polygonatum.
