Abstract

This paper demonstrates the fraction collection of the novel sugar trehalulose, using a modified ion chromatograph. The Ion Chromatography (IC) method, previously published for the analysis of trehalulose, was augmented with a suppressor and purpose-made switching valve unit. A sample of stingless bee honey was then run, following the three main steps:•Separation of trehalulose fraction•Lyophilization•Confirmation of trehalulose The method should be applicable to not only sugar analysis but to any bioactive compound separable by IC. The authors were not able to find a similar method within currently published literature.

摘要

本文展示了使用改良离子色谱仪对新型糖类海藻糖进行馏分收集的过程。先前发表的用于分析海藻糖的离子色谱（IC）方法，通过添加一个抑制器和特制切换阀装置得到了改进。随后对无刺蜂蜂蜜样本进行了分析，遵循以下三个主要步骤：

• 海藻糖馏分的分离

• 冻干

• 海藻糖的确认

该方法不仅应适用于糖类分析，还应适用于任何可通过离子色谱分离的生物活性化合物。作者在当前已发表的文献中未能找到类似方法。
