摘要:

建立一种高效液相色谱- 蒸发光散射检测(HPLC-ELSD)同时对葡萄糖、果糖、蔗糖、蔗果三糖、蔗果四糖和蔗果五糖进行测定的方法。采用氨基柱分离,乙腈- 水为流动相,梯度洗脱,流速1.0ml/min,ELSD 漂移管温度85℃,载气为空气,流速2.0L/min。结果表明,在该条件下六种糖的组分都能够得到较好的分离,线性良好,回收率为97.62%~99.55%,相对标准偏差(RSD)小于3%(n=5)。该方法稳定、准确,适合于单糖、双单及低聚糖的检测及含量测定。

Abstract:

A HPLC-ELSD method was established for the simultaneous quantitative analysis of glucose, fructose, sucrose, GF2, GF3, and GF4. The chromatographic separation was achieved on an amino column using a mobile phase composed of a mixture of acetonitrile and water at a flow rate of 1.0 ml/min by gradient elution. The ELSD drift tube temperature was set at 85 ℃ and the carrying gas was air. Under the above conditions, all glucose, fructose, sucrose, GF2, GF3 and GF4 could be well separated, and the spiked recoveries were 97.62%–99.55% with a RSD less than 3% (n = 5). This method is accurate, rapid, simple and reproducible, and thus it is suitable for the determination of monosaccharides, disaccharides, and oligosaccharides.

Key words: HPLC-ELSD, monosaccharide, disaccharide, fructo-oligosaccharides
