摘要:

建立HPLC-ELSD法测定菊粉中9种蔗果寡糖的含量, 色谱系统组成: 色谱柱: Waters XBridge? Amide (4.6 mm × 250 mm, 5 μm); 流动相: CH3CN–H2O, 梯度洗脱; 流速: 1.2 mL/min; 柱温: 30 oC; 检测器: Agilent Technologies 380-ELSD, 漂移管温度: 55 oC, N2流速: 1.8 L/min, 进样量: 15 μL。实验结果是9种菊粉型果寡糖分别在: 蔗果三糖 3.81–30.60 μg, R2 = 0.99969; 耐斯糖 3.73–29.97 μg, R2 = 0.99981; 蔗果五糖 3.82–30.69 μg, R2 = 0.99993; 蔗果六糖3.80–30.48 μg, R2 = 0.99995; 蔗果七糖3.73–29.96 μg, R2 = 0.99993; 蔗果八糖3.78–30.30 μg, R2 = 0.99983; 蔗果九糖3.82–30 μg, R2 = 0.99989; 蔗果十糖3.71–29.80 μg, R2 = 0.99974; 蔗果十一糖3.61–29.00 μg, R2 = 0.99970范围内线性关系良好, 回收率在96.48%–100.84% (n = 6)。该方法简单、准确, 具有良好的重复性, 为有效评价菊粉的质量提供了分析方法。

Abstract:

To develop an HPLC-ELSD method for the determination of nine inulin-type fructo-oligosaccharides in inulin, the HPLC-ELSD system consisted of Waters XBridge? Amide column (4.6 mm × 250 mm, 5 μm) with a gradient elution mobile phase consisting of acetonitrile and water at a flow rate of 1.2 mL/min at 30 oC. The detector was an Agilent Technologies 380-ELSD. The drift tube temperature for the ELSD was set at 55 oC with a nitrogen flow rate of 1.8 L/min. The injection volume was 15 μL. The results showed that the detection range for the nine inulin-type fructo-oligosaccharides was 3.81–30.60 μg R2 = 0.99969 for kestose, 3.73–29.97 μg R2 = 0.99981 for nystose, 3.82–30.69 μg R2 = 0.99993 for fructosylnystose, 3.80–30.48 μg R2 = 0.99995 for GF5, 3.73–29.96 μg R2 = 0.99993 for GF6, 3.78–30.30 μg R2 = 0.99983 for GF7, 3.82–30 μg R2 = 0.99989 for GF8, 3.71–29.80 μg R2 = 0.99974 for GF9, 3.61–29.00 μg R2 = 0.99970 for GF10, respectively. The recovery of the nine oligosaccharides ranged between 96.48%–100.84% (n = 6). The method was simple, accurate, and reproducible that it could be used as an analytical method for evaluating the quality of inulin effectively.
