摘要:

本研究旨在建立高脂肪饮食模型,用于评价胡椒酸乙酯的抗高脂血症活性,建立HPLC-MS/MS法测定口服给药后胡椒酸乙酯在大鼠血浆和肝脏中的药代动力学。给大鼠口服施用剂量为50 mg /kg的胡椒酸乙酯化合物。在给0.510小时通过HPLC检测血浆和肝脏中的胡椒酸乙酯浓度。通过DAS1.0软件分析药代动力学参数。血浆和肝胡椒酸乙酯的浓度-时间曲线符合二室模型。胡椒酸乙酯在胃肠道中迅速被吸收,并且可在口服给药后0.5小时在血和肝脏中检测到。

Abstract:

In the present study, we aimed to establish high-fat diet model for evaluating anti-hyperlipidaemic activity of GBA and to establish the HPLC-MS method for measuring the pharmacokinetics of GBA in rat blood plasma and liver after oral administration. Rats were orally administrated with GBA at the dose of 50mg/kg body weight. GBA concentrations in blood plasma and liver were detected by HPLC from 0.510 h post administrations. The pharmacokinetic parameters were analyzed by the DAS1.0Software. The concentration-time curves of the plasma GBA and liver GBA wereconformed to two-compartment model. GBA was rapidly absorbed in the gastrointestinal tract and could be detected in plasma and liver 0.5 h after oral administration.

Key words: Long pepper, Piperinic ester GBA, Antihyperlipidaemic activity, LC-MS/MS analysis
