摘要
目的研究补骨脂二氢黄酮甲醚在大鼠体内的组织分布。方法通过超高效液相色谱-串联质谱( UPLC-MS /MS)法,分析采用Waters ACQUITY UPLC HSS T3 色谱柱( 2. 1 mm×100 mm,1. 8 μm);流动相0. 05%甲酸-乙腈,梯度洗脱;体积流量0. 3 mL/min;柱温30 ℃;ESI 离子源;正离子模式。大鼠灌胃给予补骨脂二氢黄酮甲醚( 70 mg /kg)后,于不同时间点( 0. 083、0. 25、0. 5、1、4 h)测定其在心、肝、脾、肺、肾、脑、胃、小肠中的组织浓度。结果各组织中均检测到补骨脂二氢黄酮甲醚,其组织浓度依次为胃>小肠>肝>肺>肾>脾>心>脑,除胃、小肠( 0. 25 h)外其他组织在0. 5 h 达到最高浓度。结论该方法简便、稳定、可靠,可用于补骨脂二氢黄酮甲醚的体内分析。
AIM To study the in vivo tissue distribution of bavachinin in rats.METHODS Using an ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) method, the analysis was performed on a 30 ℃ thermostatic Waters ACQUITY UPLC HSS T3 column(2.1 mm×100 mm, 1.8 μm), with the mobile phase comprising of 0.05% formic acid-acetonitrile flowing at 0.3 mL/min in a gradient elution manner, and ESI source in a positive ionization mode was selected. Rats were given intragastric administration of bavachinin(70 mg/kg), after which the tissue concentrations in heart, liver, spleen, lung, kidney, brain, stomach and small intestine were determined at different time points(0.083, 0.25, 0.5, 1, 4 h).RESULTS Bavachinin was detected in various tissues, whose tissue concentrations were in sequence of stomach>small intestine>liver>lung>kidney>spleen>heart>brain. Except for stomach and small intestine(0.25 h), the other tissues reached the highest concentration at 0.5 h.CONCLUSION This simple, stable and reliable method can be used for the in vivo analysis of bavachinin.
