| Abstract: | To determine the content of polysaccharides in Hypecoum leptocarpum, The content of polysac- charide in Hypecoum leptocarpum was measured by phenol - sulfuric acid and UV Spectrophotometry, also found that the methods of UV Spectrophotometry has the characteristic of good repeatability, good repeatability and simple. The content of polysaccharides from Hypecoum leptocarpum is 5.2%. The UV spectrophotometric method is an ideal method to determine the content ofpolysaccharide in Hypecoum leptocarpum and provide the basis for other classes also determination of polysaccharides content. |
