摘 要:目的:考察健康人口服冠心Ⅱ号煎剂后血清中阿魏酸的浓度-时间曲线和药动学参数。方法:采用高效液相色谱法测定健康男性志愿者单次口服冠心Ⅱ号(4.5g·kg-1)煎剂后血清中阿魏酸的浓度。结果:阿魏酸的浓度-时间曲线无双峰现象出现,最高血药浓度的个体间差异达6倍,Ka为(0.26±0.350)min-1,Ke为(0.013±0.004 17)min-1,t1/2Ke为(63.45±32.288)min,tmax为(24.117±14.631)min,AUC为(13 263.51±6 478.275)ng·min-1·mL-1,CL/F(s)为(0.000 44±0.000 268)L·g-1·min-1。结论:健康男性口服冠心Ⅱ号煎剂后血清中阿魏酸的血药浓度个体差异大,阿魏酸吸收快,排泄也快。OBJECTIVE: To investigate the concentration-time curve of ferulic acid(FA) in serum of healthy male volunteers after oral administration of Guanxin Ⅱ (GXEH) and to study its pharmacokinetic parameters.METHODS: Serum FA level was determined by HPLC in healthy male volunteers after single oral administration of GXEH(4.5g · kg^-1) decoction. RESULTS: No double-peak occurred in the concentration-time curve of FA.6-fold interindividual variation was noted in maximum blood drug level.The pharmacokinetic parameters were stated as follows: Ka: (0.26 ± 0.350) min^-1 Ke: (0.013 ± 0.004 17)min^-1; t1/2 Ke: (63.45± 32.288) min; tmax: (24.117 ± 14.631) min, AUC: (13 263.51 ± 6478.275) ng · min^-1 · mL^-1; CL/F(s) : (0.000 44±0.000 268)L·g^-1. min^-1.CONCLUSION :There is a significant individual FA level difference in healthy male volunteers after oral oral administration of GXEH decoction, and both the absorption and the elemination of FA are fast.
