目的:建立高效液相色谱法测定人血浆中拉莫三嗪的浓度。方法以DiamonsilTM C18反相柱(150mm ×4.6mm,5μm)为色谱柱,流动相为0.03mol· L -1醋酸铵-甲醇(58∶42);流速:1.0mL· min -1;柱温:30℃;检测波长:310nm。以乙酸乙酯为提取剂。结果拉莫三嗪浓度在0.5~24.0μg· mL -1范围内,峰面积与浓度线性关系良好;拉莫三嗪的低、中、高浓度(1.0,8.0,20.0μg· mL -1)相对平均回收率大于95%;提取回收率大于75%。日内、日间RSD均低于10%(n=5)。分析方法的检测限0.1μg· mL -1;拉莫三嗪曲线回归方程为:Y=0.0899X+0.0215,r=0.9989(n=7);结论该方法灵敏、准确、简单、快速,能够满足体内药物分析的要求。

OBJECTIVE To establish a method for determining the concentration of lamotrigine in human plas-ma by HPLC.METHODS The drug from plasma was analyzed in a reverse phase HPLC system C18 column (150mm ×4.6mm,5μm);mobile phase consisted of 0.03mol· L-1 ammonium acetate-methanol(58∶42);the flow rate was1.0mL · min-1;the detection wavelength was at 310nm.Ethyl acetate was used as extracting sol-vent.RESULTS The peak area and concentration of Lamotrigine in 0.5~24.0μg· mL-1 has good linearity.The average recoveries of lamotrigne in low,middle and high concentrations (1.0,8.0,20.0μg· mL-1 ) were over 95%respectively;the extraction recovery over 75%.The intra-day and inter-day variation ( RSD) was less than 10%( n=5).The minimum detectable concentration of lamotrigne was 0.1μg · mL-1.The regression equation was Y =0.0899X+0.0215.r=0.9989(n=7).CONCLUSION The method is sensitive,accurate,simple,fast.It is suit-able for deter mination of drug analysis.
