| Abstract
|
| [Objective] To explore the general physical and chemical properties of traditional Chinese medicine polysaccharides, and to provide a reference for the research and application of traditional Chinese medicine polysaccharides.[Methods] The basic physical and chemical properties of 17 kinds of traditional Chinese medicine polysaccharide powders were studied by colorimetry, spectroscopy and other methods, including content determination, viscosity measurement, hygroscopicity and antioxidant capacity determination.[Results] The commercially available 17 kinds of traditional Chinese medicine polysaccharide powders had high polysaccharide content, and the protein content was very low, and had good hygroscopicity and antioxidant activity. The viscosity of the polysaccharide increased with increasing solution concentration and decreased with increasing temperature.[Conclusion] The method used in this experiment can determine the physicochemical properties of 17 Chinese medicine polysaccharides, and provide theoretical support for the research of polysaccharides. |
