中文摘要: 建立一种用高效液相色谱-蒸发光检测法测定运动饮料中常用的木糖、果糖、葡萄糖、半乳糖、蔗糖、麦芽糖、 乳糖、 蔗果三糖、 蔗果四糖、 蔗果五糖等 10 种糖分的检测方法。 样品经乙腈-水提取, 过滤膜后上机检测。 采用 ZORBAX 糖分析色谱柱(4.6 mm×250 mm,5 μm)分离,以乙腈-水梯度洗脱作为流动相,用蒸发光检测器检测,外标法 峰面积定量。 结果表明,10 种糖组分在 0.01 g/100 mL~0.50 g/100 mL 浓度范围内线性良好, 相关系数 r2 为 0.996~0.999,检出限为 0.02 mg/mL~0.1 mg/mL,定量限为 0.06 mg/mL~0.3 mg/mL,加标回收率达到 90.2 %~98.5 %。

Abstract:A rapid and effective method was established for the determination of ten sugars(xylose,fructose, glucose,galactose,sucrose,maltose,lactose,1-kestose,nystose,1F- Fructofuranosyl nystose)in sports drink by high performance liquid chromatography-ELSD detection method. The samples were extracted by acetonitrilewater,and detected on the machine after filtering membrane. The separation of targeted compound was per- formed on a ZORBAX sugar analysis chromatography column(4.6 mm×250 mm, 5 μm) using acetonitrile-wa- ter as mobile phase, with ELSD detector and external standard method peak area quantification. The linear range of ten kinds sugar was in the range of 0.01 g/100 mL-0.50 g/100 mL with a correlation coefficient of 0.996-0.999. The detection limit was 0.02 mg/mL-0.1 mg/mL and the quantitative limit was 0.06 mg/mL-0.3 mg/mL. The recovery rate was 90.2 %-98.5 %.
