摘要: 本文建立了雪莲果低聚果糖的HPLC-ELSD测定方法,分析不同炮制方法雪莲果中低聚果糖的含量。用不同方法处理新鲜雪莲果,然后超声提取雪莲果粉末中低聚果糖,采用HPLC-ELSD测定,色谱柱:华谱XAmide(4.6×250 mm,5 μm),流动相:乙腈:水=75:25,流速:1 mL/min,柱温:30 ℃,检测器:ELSD,漂移管温度70 ℃。方法学考察结果表明,蔗果三糖、蔗果四糖、蔗果五糖在0.406~2.030 mg/mL、0.420~2.100 mg/mL、0.456~2.280 mg/mL范围内呈良好线性关系,平均回收率分别为101.4%、99.7%、98.6%,RSD分别为1.53%、1.29%、2.81%。该方法稳定、可靠、精密度高、重复性好,不同处理方法所得雪莲果粉末中3种低聚果糖的含量差别较大,其中用清水漂洗0.5 h,然后冷冻干燥所得雪莲果粉末中的低聚果糖含量最高。

Abstract: A new HPLC-ELSD method was established to analyze the content of fructooligosaccharides [include 1-Kestose (GF-2),Nystose (GF-3) and 1-FFructofuranosylnystose (GF-4)] in Smallanthus sonchifolius with different processing methods.The content of fructooligosaccharides was determined by HPLC-ELSD.Chromatographic separation was performed on X Amide column (4.6×250 mm,5 μm) with mobile phase of acetonitrile-water (75:25) at a flow rate of 1 mL/min,the drift tube temperature was set at 70 ℃.A good resolution and linear range were obtained under this HPLC-ELSD condition.The linear ranges of GF2,GF3 and GF4 were determined to be 0.406-2.030 mg/mL,0.420-2.100 mg/mL and 0.456-2.280 mg/mL,respectively.The average recoveries were 101.4%(1.53%),99.7%(1.29%),98.6%(2.81%).The developed HPLCELSD method was simple,reliable,accurate and reproducible.It can be used for the quality control of S.sonchifolius. The optimal preparation method was that S.sonchifolius was rinsed with water for 0.5 h,and freeze-dried to powder.
