摘　　要：目的:建立十一味参芪片中马兜铃酸Ⅰ、马兜铃酸Ⅳa和马兜铃内酰胺Ⅰ的液相色谱-质谱法(LCMS)检测分析方法。方法:Kromasil Proshell C18色谱柱(100 mm×2.1 mm,2.5μm),以乙腈-0.1%乙酸水溶液(含10 mmol·L^(-1)乙酸铵)为流动相,梯度洗脱,流速0.3 mL·min^(-1);多反应监测模式,马兜铃酸Ⅰ为m/z 359.1→298.1(定量)和m/z 359.1→296.1(定性),马兜铃酸Ⅳa为m/z 375.1→312.2(定量)和m/z 375.1→297.2(定性),马兜铃内酰胺Ⅰ为m/z 294.1→279.0(定量)和m/z 294.1→251.1(定性),建立十一味参芪片中3个马兜铃酸类成分的LC-MS,在方法学验证的基础上对所有样品进行检测分析。结果:马兜铃酸Ⅰ、马兜铃酸Ⅳa和马兜铃内酰胺Ⅰ进样量分别在2.0197~100.9829、1.9478~116.8656、1.9718~98.5880 pg时线性关系良好(r>0.999),定量限分别为1、6、2 pg,加样回收率分别为92.95%(RSD为2.28%)、80.09%(RSD为4.16%)、104.89%(RSD为3.24%)。14批十一味参芪片样品中马兜铃酸Ⅰ、马兜铃酸Ⅳa和马兜铃内酰胺Ⅰ的检出量分别为21.0~47.6、185.0~506.1、164.4~426.0 ng·g^(-1)。结论:所建立的方法快速、准确、灵敏、可靠,能够用于十一味参芪片中上述马兜铃酸类成分的筛查与分析,可为其安全性有关成分研究提供参考。Objective:To establish a liquid chromatography-mass spectrometry(LC-MS)method for the detection and analysis of aristolochic acidⅠ,aristolochic acidⅣa,and aristolactamⅠin Shiyiwei Shenqi Tablets.Methods:A Kromasil Proshell C18 chromatographic column(100 mm×2.1 mm,2.5μm)was used with acetonitrile-0.1%acetic acid solution(containing 10 mmol·L^(-1)ammonium acetate)as the mobile phase,using a gradient elution at a flow rate of 0.3 mL·min^(-1).Multiple reaction monitoring mode was employed with m/z 359.1→298.1(quantitative)and m/z 359.1→296.1(qualitative)for aristolochic acidⅠ,m/z 375.1→312.2(quantitative)and m/z 375.1→297.2(qualitative)for aristolochic acidⅣa,and m/z 294.1→279.0(quantitative)and m/z 294.1→251.1(qualitative)for aristolactamⅠ.The LC-MS method for the three components in Shiyiwei Shenqi Tablets was established,and all samples were subsequently subjected to detection and analysis based on methodological verification.Results:The linear relations of aristolochic acidⅠ,aristolochic acidⅣa,and aristolactamⅠwere good with injection volumes of 2.0197-100.9829,1.9478-116.8656,and 1.9718-98.5880 pg,respectively,with correlation coefficients(r)greater than 0.999.The respective limits of quantification were 1,6,2 pg.The recoveries of the three components were 92.95%(RSD 2.28%),80.09%(RSD 4.16%),and 104.89%(RSD 3.24%),respectively.The detected levels of aristolochic acidⅠ,aristolochic acidⅣa,and aristolactamⅠin the 14 batches of Shiyiwei Shenqi Tablets were 21.0-47.6,185.0-506.1,and 164.4-426.0 ng·g^(-1),respectively.Conclusion:The established LC-MS method is rapid,accurate,sensitive,and reliable,and can be used for the screening and analysis of the above components in Shiyiwei Shenqi Tablets,providing reference data for research on their safety-related components.
