摘要:

茴香酸对羟基苯乙酯(HPA)是中药羌活和宽叶羌活的主要生物活性成分之一。本文建立了一种快速、特异的反相高效液相色谱法(RP-HPLC)用于静脉(20 mg/kg)和灌胃(200 mg/kg)给予大鼠HPA后其在大鼠血浆的测定和药代动力学研究。血浆样品经乙酸乙酯液液萃取净化后,进样RP-HPLC系统分离和测定。分析型色谱柱为DiamonsilTM ODS C18; 浆样品分析的流动相为MeOH–H2O (v/v), 静脉给药样品分析时为75:25,灌胃给药样品分析时为70:30;流速为1.0 mL/min, UV检测波长为256 nmHPA标准曲线线性范围,静脉给药时为0.05–5.0 μg/mL (r2 = 0.9984), 灌胃给药时为0.5–10.0 μg/mL (r2 = 0.9995); 萃取回收率为82.01%–87.97%, 日内和日间精密度为1.71%–3.99%, 准确度范围为91.22%–110.5%; HPA在大口服时的绝对生物利用度为48.17%以上结果表明所建方法适合用于HPA在大鼠血浆中的测定和药代动力学研究。

Abstract:

In the present study, we developed a rapid and specific reversed-phase high-performance liquid chromatographic (RP-HPLC) method for the quantification of p-hydroxyphenethyl anisate (HPA), one of the main bioactive constituents of the roots and rhizomes ofNotopterygium incisumand N. franchetii, in rat plasma after an intravenous (20 mg/kg, i.v.) and an intragastrical (200 mg/kg,i.g.) administration to rats, respectively. The method involved a plasma clear-up step using liquid-liquid extraction by EtOAc, followed by RP-HPLC separation and detection. Separation of HPAwas performed on an analytical DiamonsilTM ODS C18 column with the mobile phase of MeOH–H2O at ratios of 75:25 (v/v) for i.v. and 70:30 (v/v) for i.g. administration. The flow-rate was 1.0 mL/min, and UV detection was performed at 256 nm. The calibration curves were linear over the ranges of 0.05–5.0 μg/mL (r2 = 0.9984) for i.v. and 0.5–10.0 μg/mL (r2 = 0.9995) for i.g. administrationin rat plasma. The extraction recoveries were in the range of 82.01%–87.97%. The intra- and inter-day precisions were between 1.71% and 3.99%, with accuracies ranging from 91.22% to 110.5%. The absolute bioavailability of an orally administered HPA in rats was about 48.17%. The developed method was suitable for the determination and pharmacokinetic studyof HPA in rat plasma.
