摘要：

建立了大鼠灌胃麻杏石甘汤后血浆中苦杏仁苷、野黑樱苷的定性及定量方法。样品经液液萃取净化处理，定性采用超高效液相色谱-串联四极杆飞行时间质谱仪（UPLC-QTOF-MS/MS），经Shim-pack XR-ODS Ⅲ色谱柱（75 mm×2.0 mm，1.6 μm）分离，定量采用超高效液相色谱-串联三重四极杆质谱仪（UPLC-Q-TRAP-MS），经Agilent C18色谱柱（50 mm×2.1 mm，1.7 μm）分离，电喷雾负离子化（ESI）及MRM模式测定，流动相均为乙腈-0.1%（v/v）甲酸水溶液。结果显示苦杏仁苷、野黑樱苷在相应浓度范围内线性关系良好（相关系数分别为0.9990、0.9970），精密度（RSD）小于9.20%，回收率为82.33%~95.25%，检出限（LOD）约为0.50 ng/mL。本方法快速简便，为血浆样品中苦杏仁苷、野黑樱苷的定性和定量分析提供良好参考。

Abstract:

A method was developed for the determination of amygdalin and its metabolite prunasin in rat plasma after intragastric administration of Maxing shigan decoction. The analytes were identified by ultra-high performance liquid chromatography-tandem quadrupole time of flight mass spectrometry and quantitatively determined by ultra-high performance liquid chromatography-tandem triple quadrupole mass spectrometry. After purified by liquid-liquid extraction, the qualitative analysis of amygdalin and prunasin in the plasma sample was performed on a Shim-pack XR-ODS Ⅲ HPLC column(75 mm×2.0 mm, 1.6 μm), using acetonitrile-0.1% (v/v) formic acid aqueous solution. The detection was performed on a Triple TOF 5600 quadrupole time of flight mass spectrometer. The quantitative analysis of amygdalin and prunasin in the plasma sample was performed by separation on an Agilent C18 HPLC column (50 mm×2.1 mm, 1.7 μm), using acetonitrile-0.1% (v/v) formic acid aqueous solution. The detection was performed on an AB Q-TRAP 4500 triple quadrupole mass spectrometer utilizing electrospray ionization (ESI) interface operated in negative ion mode and multiple-reaction monitoring (MRM) mode. The qualitative analysis results showed that amygdalin and its metabolite prunasin were detected in the plasma sample. The quantitative analysis results showed that the linear range of amygdalin was 1.05-4200 ng/mL with the correlation coefficient of 0.9990 and the linear range of prunasin was 1.25-2490 ng/mL with the correlation coefficient of 0.9970. The method had a good precision with the relative standard deviations (RSDs) lower than 9.20% and the overall recoveries varied from 82.33% to 95.25%. The limits of detection (LODs) of amygdalin and prunasin were 0.50 ng/mL. With good reproducibility, the method is simple, fast and effective for the qualitative and quantitative analysis of the amygdalin and prunasin in plasma sample of rats which were administered by Maxing shigan decoction.
