| 中文摘要:目的 建立落新妇苷组织浓度的高效毛细管电泳分析方法,并对其在小鼠体内的组织分布进行测定。方法 高效毛细管电泳之胶束电动模式测定小鼠尾静脉注射30 mg/kg落新妇苷后不同时间点各组织中药物含量。结果 落新妇苷在组织器官的浓度分布特点是:C心 > C肝 > C肾 > C脾 > C肺 > C脑。心脏组织C5 min > C15 min > C60 min,自5 min浓度达峰后呈缓慢递减趋势,C60 min仍保持较高浓度。其他组织C15 min达峰,肝脏在C15 min至C60 min均保持较高药物浓度,C60 min在各组织中浓度最高。60 min内脑组织含有较稳定药物含量。结论 落新妇苷在小鼠体内分布广泛,心、肝、肾保持较高组织浓度,且能够穿越血脑屏障分布到脑组织中。 |

| Abstract:Objective To establish a high performance capillary electrophoresis(HPCE) method for analysis of tissue distribution of astilbin in mice.Methods The model of micellar electrokinetic capillary chromatography(MECC) of HPCE was adopted after intravenous injection.The concentrations of astilbin in biological samples were determined. Results The tissue distribution feature of astilbin was Cheart > Cliver > Ckidney > Cspleen > Clung > Cbrain. The Cheart shows C5 min > C15 min > C60 min and C5 min is Cmax. But C15 min was Cmax in other tissues. The steady content of astilbin was found in brain tissue within 60 min. Conclusion Astilbin was widely distributed in main tissues, which could also permeate blood brain barrier. |
