摘要: 目的:研究蛇床子素在大鼠体内的组织分布特征,为临床合理用药提供合理依据。方法:大鼠腹腔注射30,120 mg·kg-1蛇床子素后,采用RP-HPLC法测定大鼠组织中不同时间点的药物浓度,分析蛇床子素在大鼠体内的组织分布特点。结果:大鼠ip蛇床子素后,组织分布较快,给药5 min均可检测到蛇床子素,10 min内心、肝、肺、肾均可达到峰值。当给药浓度增加4倍时,蛇床子素在各组织中的达峰时间没有显著性变化,只是相应时间点的药物浓度均略有升高,药物消除的时间也相应延长。结论:蛇床子素在大鼠组织中分布快广泛,消除也快,且可能穿越血脑屏障和血睾屏障。

Abstract: Objective: To study the tissue distribution of ostholon rats and to provide bases for clinical applications. Methods:  After osthol was administered to rats (30, 120 mg·kg-1 ;ip), the concentration of osthol in rat tissues after different time was determined by RP-HPLC. Results: Osthol distributed rapidly in the tissues after ip: eight tissues can detect osthol after 5 min. Heart, liver, lung and kidney all reached Cmax in 10 min. When the dose is increased 4 folds, Tpeaks of osthol in tissues had no significant changes, except the concentration and elimination time increased slightly corresponding to the same time-point. Conclusion: Osthol was distributed rapidly and extensively in the rat’s body and may pass through blood-brain-barrier and blood-testis-barrier.
