紫外可见分光光度法测定不同年份黄精中多糖含量
Test of the Content of the Polysaccharide in the Polygonatum with Different Ages with the Method of UV-visible Spectrophotometry
摘要
Abstract
[ Objective] The reference for the Polygonatum-planting and its products-grading was provided through the determination of the contern of the polysaccharide in the Polygonatum,with different ages in Jiuhuashan Mountain region. [ Method ] The content of polysaccharide in Polygonatum was determined with the method of phenol-sulfuric acid. [ Result ] There was a larger variation in the content of polysaccharide among different Polygonatum ages and its content was increased with its growth year-lasting. The testing result indicated the content of polysaccharide in I year old Polygonatum was the lowest with 13.02％ and the maximum content appeared in 9 year-old Polygonatum with the value of 18.44％.However,the content polysaccharide 10-year-old Polygonatum was declined with the value of 15.64％. [ Conclusion] In the actual harvest,the products of Polygonatum could be graded depending on its growth age.关键词
