摘要 目的建立液相色谱-串联质谱联用法测定人血浆中染料木素(雌激素类药物)及其葡萄糖醛酸代谢物(GGS)并研究其在健康人体中的药代动力学。方法10例健康受试者空腹口服染料木素50mg,血浆加入内标物地塞米松后,经液-液萃取,色谱柱为Capcell Pak C8(2mm×150mm,5μm),流动相为:甲醇-5mmol·L^-1乙酸铵-乙腈(70:20:10),以ESI源正离子MRM模式测定染料木素的血药浓度,GGS先酶解为原形后间接测定,用DAS2.0程序计算药代动力学参数。结果线性范围为0.3~500.0μg·L^-1(1=0.9983),回收率在92.9%~104.9%,绝对回收率在74.2%~89.2%,13内、13间变异(RSD)均〈15%。染料木素和GGS的主要药代动力学参数:tmax分别为(5.0±I.3),(6.0±2.4)h,Cmax分别为(10.1±6.3),(218.7±68.6)μg·L^-1,AUC0-1分别为(31.2±10.3),(3344.0±1635.0)μg·h·L^-1,AUC0-∞分别为(33.9±11.4),(3703.0±2031.0)μg·h·L^-1。结论测定方法灵敏、准确、快速、特异性强,适用于染料木素药代动力学研究。 Objective To establish a LC/MS/MS method in order to determine concentration of genistein and glucuronidated genistein (GGS) in plasma, and study its pharmacokinetics in healthy human. Methods Ten healthy volunteers were given a single oral dose of genistein 50 mg. The plasma sample were prepared by liquid -liquid extraction method with ethyl acetate, used the Capcell Pak C8(2 mm± 150 mm, 5 μm) as analytical column, the mobile phase consisted of methanol- 5 mmol L^-1 NH4AC buffer - acetonitrile (70 : 20 : 10 ). The plasma concentrations were detected in ESI positive MRM mode, and the GGS was hydrolyzed to genistein and detected indirectly. The pharmacokinetic parameters were analyzed by DAS ( ver 2.0). Results The good linear range of genistein was 0. 5 - 500. 0 g · L^-1 ( γ = 0. 9983 ). The recovery and the absolute recovery was 92. 9% - 104. 9% and 74. 2% - 89. 2%, respectively. The within- day and between -day deviations were less than 15%. The pharmacokinetic parameter of genistein and GGS were as follows: t were (5.0± 1.3) and (6.0±2.4) h, Cmax were (10.1 ± 6.3) and (218.7±68.6) μg·L^-1, AUC0-1 were (31.2 ± 10. 3) and (3344.0 ± 1635.0) μg·L^-1, AUC0-1 were (33.9±11.4) and (3703.0 ±2031.0)μg·h·L^-1. Conclusion The method was sensitive, accurate, rapid, specific, suitable for pharmacokinetics study of genistein
