林下参片中总糖、还原糖及糖醛酸的含量测定

摘要

采用紫外分光光度法测定林下参片中总糖、还原糖及糖醛酸的含量，结果显示，其含量分别为66.35％、12.58％及1.19％。本研究为首次通过紫外分光光度法对林下参片中的糖类成分进行含量测定，为林下参片的科学评价提供了科学依据。%To determine the contents of carbohydrates in Linxiashen tablets .The total sugar ,reducing sugar and uronic acids in Linxiashen tablets were detected by ultraviolet spectrophotometry .The content of total sugar ,reducing sugar and uronic acids were 66.35% ,12.58% and 1.19% respectively .It is the first time to determine the contents of carbohydrates by ultraviolet spectrophotometry ,which provides a scientific basis for the development of Linxiashen tablets .
