摘要(Abstract)：

该文采用HPLC-Qq Q-MS技术对不同产地珠子参中的5种成分建立含量测定方法。色谱条件为Zorbax XDB-C18(4.6mm×100 mm,1.8μm),流动相乙腈(含0.1%甲酸)-0.1%甲酸水梯度洗脱,流速0.5 m L·min-1,柱温30℃。质谱条件为正离子检测模式,采用电喷雾电离源(ESI),扫描方式为多反应离子监测模式(MRM),定量分析离子分别为人参皂苷Re m/z 203.2,人参皂苷Rg1m/z 202.9,人参皂苷Rf m/z 365.0,人参皂苷Rd m/z 789.1,人参皂苷Ro m/z 360.9,干燥气流速10L·min-1,干燥气温度300℃,雾化气压力45 psi(1 psi=6.895 k Pa),毛细管电压4 000 V。结果显示5种人参皂苷的含量在一定范围内线性关系良好(r>0.9991)。人参皂苷Re、人参皂苷Rg1、人参皂苷Rf、人参皂苷Rd、人参皂苷Ro线性范围分别在3.33~66.60μg(r=0.999 1),2.83~56.54μg(r=0.999 2),0.32~6.51μg(r=0.999 2),12.55~251.00μg(r=0.999 3),0.85~16.90μg(r=0.999 5),范围与色谱峰面积呈良好的线性关系,加样回收率(n=6)均在100.8%~104.6%,RSD均<3.0%。该方法简单、准确,重复性好,可用于人参皂苷类成分的含量测定。
