UHPLC-MS/MS同时测定参桂鹿茸丸中5种人参皂苷的含量

    Simultaneous determination of 5 ginsenosides in Shengui Lurong Pills by UHPLC-MS/MS

    • 摘要: 目的 建立同时测定参桂鹿茸丸中5种人参皂苷含量的UHPLC-MS/MS方法。方法 选用Agilent C18色谱柱(100 mm×2.1 mm,1.8 μm),柱温25 ℃,以甲醇-0.1%甲酸水梯度洗脱,流速为0.3 mL·min–1,ESI离子源,采用正离子多反应监测(MRM)监测模式。结果 人参皂苷Re、Rg1、Rf、Rb1以及拟人参皂苷F11浓度范围内线性良好,r2均>0.999 6,加样回收率为96.3%~104.9%,RSD(n=9)均<3.0%,仪器精密度、稳定性以及重复性的RSD均<3.0%。结论 该方法简单,准确,重复性好,可用于参桂鹿茸丸的质量控制和评价。

       

      Abstract: OBJECTIVE To establish a UHPLC-MS/MS method for simultaneous determination of five ginsenosides in Shengui lurong pills. METHODS The determination was performed on Agilent C18(100 mm×2.1 mm, 1.8 μm) column with column temperature of 25 ℃. Methanol and 0.1% aqueous formic acid solution were used as mobile phase for gradient elution with the flow rate of 0.3 mL·min-1. Ion source was electrospray ion source, positive ion mode monitoring was conducted and MRM mode was adopted. RESULTS The linear ranges of ginsenoside Re, Rg1, Rf, Rb1 and pseudo-ginsenoside F11 had good resolution and linear relationships(r2≥0.999 6). The spiked recoveries were in the range of 96.3%-104.9% with RSD(n=9)<3.0%. RSDs of instrument precision, stability and reproducibility tests were <3.0%. CONCLUSION The method is simple, accurate, reliable, and can be uesd for quality control and evaluation of Shengui Lurong pills.
