摘要: 目的 建立用于测定吴茱萸碱血药浓度的液相色谱-串联质谱联用分析方法, 并研究吴茱萸碱在大鼠体内的药代动力学。 方法 6 只大鼠灌胃给药吴茱萸碱100 mg/kg, 眼底取血, LC-MS MS 法测定血药浓度, 并用DAS 药代动力学程序拟合计算药代动力学参数。 结果 吴茱萸碱浓度在0.2 ~ 50 ng mL内, 线性关系良好(r2 =0.9997)。提取回收率96.12 %~ 99.46 %, 日内、日间RSD 分别为4.61 %~ 13.51 %和5.65 %~ 11.49 %。主要药代动力学参数为:Cmax =(5.3±1.5)ng mL;tmax =(22±8)min;t 1 2 =(451±176)min 。 结论 建立的LC-MS MS 方法专属性强, 灵敏度高, 可用于吴茱萸碱的体内定量分析。

Abstract: AIM: To establish an LC-MS MS method for determination of evodiamine concentration in rat plasma and to study its pharmacokinetic profile in rats. METHODS: Six rats were administrated (i.g.)evodiamine at the dose of 100 mg/kg.Blood samples were collected from eye socket.Evodiamine concentration in rat plasma was determined by LC-MS MS method.The pharmacokinetic parameters were calculated using DAS program. RESULTS: A good linear relationship was obtained in the concentration range (0.2-50.0 ng mL) studied (r2 =0.9997).Average recoveries ranged from 96.12 % to 99.46 %.Intra-and inter-day relative standard deviations were 4.61 %-13.51 % and 5.65 %-11.49 %, respectively.The main pharmacokinetic parameters of evodiamine were as follows:Cmax(5.3±1.5) ng mL;tmax(22±8)min;t 1 2(451±176)min. CONCLUSION: A selective and sensitive liquid chromatography-tandem mass spectrometric (LC-MS MS)method for the quantification of evodiamine in rat plasma is developed and validated.This method is successfully applied for the pharmacokinetic studies of evodiamine in rats.
