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。
