ABSTRACT
Objective: To study the change rule of polysaccharide content in different processed products of polygonatum from Shaanxi. Methods:The content of polysaccharides was determined by UV spectrophotometry at the wavelength of 580nm after colored by 0. 2% anthranone-sulfuric acid solution. Results: The content of polysaccharide was significantly different among different pro-cessed products of polygonatum, and that in the raw slices was the highest followed by alcohol evaporate slices, while that in the steamed samples was the lowest. Furthermore, the extract and the content in the different processed samples of polygonatum showed a similar regularity. Conclusion:The results of the research can provide reference for the quality control and processing methods of po-lygonatum slices from Shannxi.
