摘要: 目的: 建立HPLC 丹皮酚胶囊血浓度测定方法, 评价丹皮酚胶囊的药代动力学特点。方法: 24名健康志愿者单剂量口服160 mg 丹皮酚胶囊, 按设定时间采集肘静脉血经乙睛萃取处理, 以XB-C18(250 mm×4.6 mm, 5 μm) 色谱柱为固定相, 四氢呋喃-甲醇-水-磷酸(6:60:34:0.1) 为流动相测定丹皮酚血浆浓度。采用DAS2.0 计算丹皮酚主要药动学参数。结果: 丹皮酚线性范围10~500 ng/mL, 最低检出浓度为10 ng/mL 。主要药代动力学参数:Cmax为(116±46) ng/mL, tmax 为(1.02±0.13) h, t1/2 为1.03 h 。结论: 建立的HPLC 方法特异性强、灵敏度高, 可用于丹皮酚血药浓度测定和人体药动学研究。

Abstract: AIM: To establish a sensitive HPLC method for determining the concentrations of paeonol in human plasma and to evaluate its pharmacokinetic characteristics. METHODS: A single oral dose of 160mg paeonol capsules was given to 24 Chinese healthy volunteers. Paeonol was separated on a XB-C18 column with tetrahydrofuran-methanol-water-phosphonic acid (6:60:34: 0.1, V:V) as mobile phase.The plasma concentrations of paeonol were determined and its pharmacokinetic parameters were calculated and evaluated using DAS 2.0. RESULTS: The linear range of the paeonol was 10-500 ng/mL and the determination limit was 10 ng/mL.The main pharmacokinetic parameters, as Cmax, tmax, t1/2, AUC0-3, AUC0-∞ after a single dose of paeonol capsules were (116±46) ng/mL, (1.02±0.13) h, (1.03±0.35) h, (174±45) ng/mL, (217±56) ng/mL, respectively. CONCLUSION: The HPLC method for determining paeonol concentration in plasma is rapid, sensitive and suitable for pharmacokinetic studies.
