摘要
目的:建立超高效液相联用质谱法(UHPLC—MS/MS)同时测定肾八味胶囊中6种皂苷(人参皂苷Rb1、三七皂苷R1、人参皂苷Rg1、人参皂苷F1、人参皂苷F2、原人参三醇)的含量。方法:采用Zorbax SB-C18色谱柱(2.1mm×50mm,1.8μm),以0.1%甲酸水溶液(A相)-0.1%甲酸乙腈溶液(B相)为流动相梯度洗脱(0~3.2min,20%~35%B相;3.2~3.4min,25%~45%B相;3.4~7.0min,45%~55%B相),流速为0.3ml/min,柱温20℃,进样量5μl,采用电喷雾离子源(ESI)正离子模式下检测。结果:人参皂苷Rb1、三七皂苷R1、人参皂苷Rg1、人参皂苷F1、人参皂苷F2和原人参三醇在相应的线性范围内线性关系良好(r≥0.9991),日内和日间RSD为0.54%~2.92%,平均加样回收率为97.06%~99.76%,重复性和稳定性良好。结论:本研究建立的UHPLC-MS/MS法能够快速、简便、灵敏地测定肾八味胶囊中6种皂苷的含量。主成分分析(PCA)和偏最小二乘判别分析(PLS-DA)可对有效期不同的样品进行区分,由此可为肾八味胶囊的质量控制提供科学依据。
Objective:To develop an UHPLC-MS/MS method for simultaneous determination of six saponins(ginsenoside Rb1, notoginsenoside R1 ,ginsenoside Rg1 ,ginsenoside F1 ,ginsenoside F1 and protopanaxatriol) in Shenbawei capsules. Methods: Separation was performed on a Zorbax SPrC18 column(2.1 mm× 50 mm, 1.8μm) with column temperature at 20 ℃. The mobile phase was composed of 0.1% formic acid aqueous solution(phase A) and 0.1% formic acid acetonitrile solution(phase B) at a gradient elution(0-3.2 min, 20 %-35 % phase B; 3.2-3.4 min, 25 %-45 % phase B; 3.4-7.0 min, 45 %-55 % phase B) at a flowrate of 0.3 ml/min and sample size of 5 /11. Mass spectrometry was performed using electro spray ionization(ESI), combined with positive ion scanning switch. Results:The method was validated with respect to linearity(r≥0. 999 1), precision(RSD between 0.54% and 2.92%) and accuracy(recovery rates between 97.06% and 99. 76%). The repeatability and stability were also good. Conclusion:The method was proved to be rapid, simple, sensitive and could be used to determine saponins contents in Shenbawei capsules. The principal components analysis(PCA) and partial least squares discriminant analysis(PLS-DA) could successfully distinguish samples with different expiration dates, which provided reference for quality evaluation of Shenbawei capsules.
