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.
