摘要:

采用核磁共振波谱分析技术,确定了蜂蜜中葡萄糖、果糖和蔗糖在重水中的各种构型,归属了蜂蜜中葡萄糖、果糖和蔗糖的质子核磁共振谱的主要特征峰,以邻苯二甲酸氢钾作内标,同时对蜂蜜中上述三种主要糖进行了定量分析。葡萄糖、果糖和蔗糖测定结果的相对标准偏差分别为0.33%、0.17%、1.34%,回收率分别为96.68%、98.03%、95.56%。该法取样量少,直接定量,所得结果重现性好、准确度高,为蜂蜜的质量标准研究提供一种简单可行的方法。

Abstract:

Various configurations of glucose, fructose and sucrose in honey were determined by nuclear magnetic resonance (NMR) spectroscopy when dissolved in heavy water, their main characteristic peaks in the 1H-NMR spectrum were attributed, and their contents was measured with potussium biphthalate as an internal standard. The RSDs of determination of glucose, fructose and sucrose were 0.33%, 0.17% and 1.34%, respectively, and mean recoveries for them in spiked honey were 96.68%, 98.03% and 95.56%, respectively. This method can be applied to direct determination of small-amount samples with stable and repeatable results and high precision for study of quality standards of honey.

Key words: nuclear magnetic resonance (NMR), honey, glucose, fructose, sucrose, determination
