摘  要:目的建立大鼠血浆中黄芪甲苷的测定方法。方法以尼群地平为内标,采用LC-MS/MS方法,以Kiomasil C18(150 mm×4.6 mm,5μm)色谱柱为分析柱,甲醇-0.1%甲酸水(70∶30,V/V)为流动相,梯度洗脱,流速为700μL.min-1,柱温为恒温,进样量为20μL。质谱检测采用多反应监测(MRM)模式,ESI源,分别监测离子反应m/z 785.6m/z 143.1(黄芪甲苷)和m/z 361.3m/z329.2(内标尼群地平)。结果在0.202~202.000μg.L-1浓度范围内具有良好的线性关系,典型回归方程为:Y=0.004 9c+0.070 6,r=0.997 0(n=9)。回收率为(91±8)%(n=9)。准确度、精密度均符合生物样品的测定要求,最低定量浓度为0.202μg.L-1。大鼠尾静脉注射和口服黄芪甲苷(20μg.g-1)体内主要药动学参数:t1/2(1.37±0.02)h、tmax(0.08±0.00)h、AUC0-t(4 717.54±178.20)μg.h.L-1、AUC0-∞(6 444.68±521.25)μg.h.L-1和t1/2(1.84±0.17)h、tmax(1.00±0.00)h、AUC0-t(499.27±10.14)μg.h.L-1、AUC0-∞(1 593.52±217.19)μg.h.L-1。结论该检测方法简便、准确、专属性强,能够满足黄芪甲苷在大鼠体内药动学研究的需要。AIM To establish a high performance liquid chromatography tandem mass spectrometry (LC-MS/MS) method for the determination of the astragaioside 1V in rat plasma. METHODS Nitrendipine was selected as internal standard (IS). The chromatographic separation was performed on a Kiomasil C18 column (4.6 mm x 150 mm, 5 μm) with a mobile phase of methanol-0.1% formic acid in water (70 : 30, V/V) at a flow rate of 700 μL-min-1. The temperature was set to constant temperature. Analytes were detected with a 3200 QTRAP quadrapole mass spectrometer equipped with an electrospray ionization source in positive muhiple reaction monitoring mode m/z 785.6→m/z 143.1 (astnagaloside IV) and m/z 361.3 →m/z 329.2 (IS, nitrendipine). RESULTS The linear concentration range of astragaloside IV was 0.202 - 202.000 μg.L-1 (r = 0.997 0). The typical regression equation was Y = 0.004 9c ± 0.070 6 (n = 9), with the average recovery rate of (91 ± 8)% (n = 9). The limit of quantitation was 0.202 μg.L-1. The main pharmacokinetic parameters of the astragaioside IV 20 μg.g-1 in rat were as follow: t1/2 (1.37 ± 0.02)h, tmax (0.08 ± 0.00) h, AUC0-t (4 717.54 ± 178.20) μg-h.L-1, AUC0-∞ (6 444.68 ± 521.25) μg. h. L-1 and t1/2 ( 1.84 ± 0.17) h, tmax ( 1.00 ± 0.00) h, AUC0-t (499.27 ± 10.14) μg. h. L-1, AUC0-∞ (1 593.52 ± 217.19) μg .h .L-1. CONCLUSION The established method is rapid, sensitive, and reproducible, and suitable for the pharmacokinetics study of astragaloside IV in rats.
