木瓜中多糖和微量元素含量分析

Analysis of Oligosaccharides and Trace Element in Fructus Chaenomelis

苯酚 -硫酸光度法和原子吸收分光光度法分别测定了木瓜中多糖和微量元素的含量。多糖测定的相关系数为 0 .994 3,平均含糖量为 1 0 .4 9%;微量元素测定回收率为 97.1 %— 1 0 5 .9%,RSD为 2 .4 7%—7.6 0 %。本方法简单可靠 ,适用于木瓜及其制品的常规检测。

The contents of oligosaccharides and trace elements in fructus chaenomelis were determined by phenol-sulfuric acid and spectrophotometric method,respectively.The correlation coefficient of oligosaccharides is 0.9943 with the average content of 10.49%.The recovery for trace elements is in the range of 97.1%—105.9% with RSD of 2.47%—7.60%.The method is reliable and simple and can be applied to the analysis of fructus chaenomelis and related products.
