摘要: | 目的:研究大鼠灌服青连宁心胶囊后盐酸小檗碱的组织分布规律。方法:取36只大鼠ig青连宁心胶囊(4 g/kg),分别于给药后1、3、5、7、9、11 h各取6只大鼠解剖取心脏、肝、脾、肺、肾等组织,另取6只大鼠空白组织为对照。采用高效液相色谱法测定各组织中盐酸小檗碱的浓度,色谱柱为Zorbax Eclipse XDB-C18,流动相为乙腈-0.05 mol/L磷酸二氢钾(25 ∶ 75,pH=3.17),检测波长为345 nm,流速为1.0 ml/min,柱温为25 ℃。结果:各组织中盐酸小檗碱检测线性范围均为0.404 8~404.800 0 μg/ml(r= 0.999 5~0.999 7),方法回收率为90%~102%(RSD均不大于6.49%,n=6),提取回收率为87%~101%(RSD均不大于5.45%,n=6)。给药1 h后,各组织中均能检测到盐酸小檗碱,其中以肝中浓度最高;给药3 h后,心脏中盐酸小檗碱的浓度即达到最大值;给药5 h后,肾中盐酸小檗碱浓度最高,但肝中浓度不断升高,且在给药7、9、11 h后检测浓度均最高;给药11 h后,肝中盐酸小檗碱浓度达365.263 4 μg/ml。结论:大鼠ig青连宁心胶囊后盐酸小檗碱能较快分布到各组织,其中在肝和心脏中分布较快、较多。 |
ABSTRACT: | OBJECTIVE: To study the tissue distribution regularity of berberine hydrochloride in rats after intragastric administration of Qinglian ningxin capsules. METHODS: 36 rats were given Qinglian ningxin capsules (4 g/kg) intragastrically, and the heart, liver, spleen, lung, kidney tissues were collected 1, 3, 5, 7, 9, 11 h after medication, 6 rats each. Other 6 rats were seleted to collect blank tissue as control. The concentration of berberine hydrochloride in each tissue was determined by HPLC. Zorbax Eclipse XDB- C18 column was used with mobile phase consisted of acetonitrile-0.05 mol/l potassium dihydrogen phosphate (25 ∶ 75, pH=3.17) at the flow rate of 1.0 ml/min. The detection wavelength was set at 345 nm and column temperature was 25 ℃. RESULTS: The linear range of berberine hydrochloride in each tissue were 0.404 8-404.800 0 μg/ml (r=0.999 5-0.999 7); method recovery was 90%-102% (all RSDs≤6.49%, n=6) and extraction recovery was 87%-101% (all RSDs≤5.45%, n=6). 1 h after medication, berberine hydrochloride was found in each tissue, and its concentration was the highest in liver. The concentration of berberine hydrochloride in heart reached the maximum 3 h after medication; that in kidney reached the maximum 5 h after medication; that in liver was increasing and reached the maximum 7, 9 and 11 h after medication; that in liver reached 365.263 4 μg/ml 11 h after medication. CONCLUSIONS: Berberine hydrochloride can be delivered in each tissue of rats rapidly after intragastric administration of Qinglian ningxin capsules. The distribation of it is higher and faster in liver and heart. |
