Abstract:
[Objective]To determine the content of Polygonum multiflorum thunb. Polysaccharide and the refined. [Methods] The sulfuric acid-phenol method was used. [Results] ?_ max = 486nm. The linear rang was 10.5～94.5?g?L -1 .And the average recovery was 101.23%(n=5,RSD=3.03%). The content of Polygonum multiflorum thunb. Polysaccharide was 14.28% and the refined was 19.03%. [Conclusion] The method was simple,rapid and reliable.
