摘要(Abstract):

目的:建立同时测定灯盏细辛注射液中绿原酸、咖啡酸、1,5-二-O-咖啡酰奎宁酸、野黄芩苷的含量测定方法。方法:采用高效液相色谱法,Agilent Zorbax SB-C18(4.6 mm×150 mm,5μm)色谱柱;流动相A-0.1%甲酸水溶液,B-乙腈,梯度洗脱;流速1.0 mL·min(-1),柱温35℃,进样量20μL。结果:绿原酸、咖啡酸、1,5-二-O-咖啡酰奎宁酸、野黄芩苷分别在0.025~0.800(r=0.999 0),0.027~0.850(r=0.999 9),0.062~1.978(r=0.999 7),0.118~3.770μg(r=0.999 9)成良好的线性关系,加样回收率分别为97.19%(RSD 1.16%);100.45%(RSD 1.16%);97.32%(RSD 1.43%);103.81%(RSD 0.70%)。结论:本法简便、快捷,结果准确、重复性好,可用于灯盏细辛注射液中4种有效成分的含量测定。
Objective:To establish a method for determination of chlorogenic acid,caffeic acid,caffeoylquinic acid and Scute- llarin in Dengzhan Xixin injection.Mothod:The HPLC method was carried out on Agilent Zorbax SB-C18 column(150 mm×4.6 mm,5μm)evaluated with acetonitrile-0.1% formic acid as mobile phase,gradient elution;the flow rate was 1.0 mL·min(-1),柱温35℃,进样量20μL。结果:绿原酸、咖啡酸、1,5-二-O-咖啡酰奎宁酸、野黄芩苷分别在0.025~0.800(r=0.999 0),0.027~0.850(r=0.999 9),0.062~1.978(r=0.999 7),0.118~3.770μg(r=0.999 9)成良好的线性关系,加样回收率分别为97.19%(RSD 1.16%);100.45%(RSD 1.16%);97.32%(RSD 1.43%);103.81%(RSD 0.70%)。结论:本法简便、快捷,结果准确、重复性好,可用于灯盏细辛注射液中4种有效成分的含量测定。
