【摘要】 目的建立测定人血浆中氯氮平浓度的高效
液相色谱法。方法以DiamonsilTMC18反相柱(150 mm×4.6 mm,5μm)为色谱柱,流动相为0.03 mol.L-1醋酸铵-甲醇(25:75);流速0.8 mL.min-1,柱温40℃,检测波长254nm。以醋酸乙酯与二氯甲烷(80:20)为提取剂。结果氯氮平的高、中、低(1 000.0,400.0,10.0 ng.mL-1)3种浓度平均回收率分别为98.28%,97.63%,101.41%,日内、日间精密度RSD均<7%(n=5);分析方法的检测限为5.0ng.mL-1;线性范围为10.0~1 000.0 ng.mL-1。曲线方程:C=25.69F+3.47,r=0.999 7(n=10)。结论该方法灵敏、准确、简单、快速,可用于临床血药浓度监测和药动学研究。 更多还原
【Abstract】 Objective To establish a method for determining the concentration of clozapine in human plasma by HPLC. Methods The drug from plasma was analyzed in a reverse phase HPLC system C18 column(150 mm×4.6 mm,5 μm);mobile phase consisted of 0.03 mol·L-1ammonioum-methanol(25:75);the flow rate was 0.8 mL·min-1;the detection wavelength was at 254 nm.Ethyl acetate and dichloromethane(80:20) was used as extracting solvent. Results The average recoveries of clozapine in high,middle and low concentrations(100... 更多还原
