目的 研究大鼠脑缺血再灌注后,血栓通主要成分人参皂苷Rb₁、Rg₁、Re、Rd及三七皂苷R₁在脑内的分布状况。方法 采用超高效液相色谱质谱联用法(UPLC-MS/MS)测定给予不同浓度的血栓通后,不同时间点血栓通主要成分在正常脑组织和缺血脑组织中的含量。结果 结果表明,血栓通活性成分在脑缺血大鼠脑中的分布远高于正常大鼠,并且其在脑内的含量随再灌注时间的延长降低。结论 脑缺血再灌注后,血脑屏障开放,注射用血栓通(冻干)可以透过血脑屏障发挥作用。

Objective To study the intracephalic distribution of ginsenosides Rb₁, Rg₁, Re, Rd and notoginsenoside R₁ from Xueshuantong Injection (lyophilized powder) after ischemia-reperfusion. Methods Using ultra performance liquid chromatography tandem massspectrometry (UPLC-MS/MS), the contents of active ingredients in Xueshuantong Injection in normal brain tissue and ischemic tissue at different drug concentration and time points were measured. Results The distribution of active ingredients of Xueshuantong Injection in cerebral ischemia brain was much higher than that of normal ones, and the content of active ingredients in brain reduces with reperfusion prolonged. Conclusion Xueshuantong Injection plays its role because blood brain barriar opens after ischemia-reperfusion.
