摘要
目的:研究丹皮酚在小鼠血浆和脑组织中的分布。方法:采用气相色谱-质谱法测定丹皮酚灌胃后小鼠血浆和脑组织中的浓度,用3p97软件计算两者的药动学参数并比较评价。结果:丹皮酚在血浆、脑组织的主要药动学参数Ka分别为99.3、18.22h-1,t1/2α分别为0.04、0.05h,t1/2β分别为3.95、71.23h,t1/2ka分别为0.01、0.04h,Cmax分别为4.57μg.mL-1、0.51μg.g-1,AUC0→t分别为2.32μg.h.mL-1、1.62μg.h.g-1。结论:丹皮酚灌胃小鼠后吸收迅速,血浆中消除快,不易透过血脑屏障,但在脑组织中停留时间长。
OBJECTIVE: To study the distribution characteristics of paeonol in the plasma and brain tissue of mice. METHODS: The concentrations of paeonol in the plasma and brain tissue of mice were determined by GC- MS and the pharmacokinetic parameters of paeonol calculated with 3P97 software were compared and evaluated. RESULTS: The main pharmacokinetic parameters of paeonol in the plasma and the brain were as follows: Ka : (99.3 h 1 vs 18.22 h 1) ; t 1/2a: (0.04 h vs 0.05 h) ; t 1/aa: (3.95 h vs 71.23 h) ; t 1/a,: (0.01 h vs 0.04 h) ; Cmax: (4.57 μg · mL ^-1 vs 0.51 μg · g ^-1) ;AUC0→t : 2.32 μg · mL^- 1· h, 1.62μg· g^- 1· h.CONCLUSION: After intragastric administration, paeonol rapidly absorbed by mice and quickly eliminated from plasma, and it had difficulty in passing through the blood-brain barrier but it has long retention time in brain tissue.
