摘要: 比较紫外分光光度法和高效液相色谱法测定和田红枣中总糖含量的差异,探讨和田红枣中总糖含量测定方法的可靠性。采用苯酚-硫酸显色-紫外分光光度法在489 nm波长处测定和田红枣中总糖的含量。高效液相色谱法是测定和田红枣中三种糖(果糖、葡萄糖和蔗糖)的含量,其之和即为总糖的含量。苯酚-硫酸显色-紫外分光光度法测得的和田红枣中总糖的含量为603.30 mg/g。高效液相色谱法测得的和田红枣中总糖的含量为598.01 mg/g。紫外分光光度法和高效液相色谱法测定的和田红枣中总糖的含量差异小,高效液相色谱法可以代替紫外分光光度法对和田红枣中总糖的测定。

Abstract: To investigate the quantification method of total sugar in Hetian jujube using UV spectrophotometry and HPLC,total sugar content in Hetian jujube was determined by using phenol-sulfuric acid method and UV spectrophotometry at 489 nm.Total sugar in Hetian jujube consist three main types,including fructose,glucose,and sucrose,and their contents could be determined by HPLC,respectively.The content of total sugar in Hetian jujube was 603.30 mg/g by UV spectrophotometry,and it was 598.01 mg/g by HPLC analysis.The contents of total sugar in Hetian jujube determined by UV spectrophotometry and HPLC had small difference,which suggests that both methods are suitable to determine the total sugar in Hetian jujube.However,the HPLC method has advantages of simplicity of operation,system accuracy,high precision and reproducibility,and it is more suitable to be used for the quality control of Hetian jujube.

Key words: Hetian jujube, total sugar, HPLC, UV spectrophotometry
