摘要:[ 目的] 建立丹芪偏瘫胶囊中间体的高效液相色谱仪/二极管阵列检测器/蒸发光散射检测器(HPLC/
DAD/ELSD)指纹图谱,为全面科学控制丹芪偏瘫胶囊的质量提供新方法。 [方法] 采用HPLC/DAD/ELSD 串联技
术,色谱柱:Waters Bridge 柱,RP18 (4.6 mm×250 mm ,5.0 μm)。流动相A :10%乙腈—冰醋酸(500∶2.2 ,v/v),B :90%
乙腈—冰醋酸(500∶2.2 ,v/v),柱温:35 ℃,进样量:20 μL ,流速:1 mL/min ,检测波长:254 nm ;漂移管温度: 50 ℃,
加热器级别:68% ,载气压力:35PSI,增益值:60。 [结果] 建立的方法对丹芪偏瘫胶囊中紫外吸收的成分和无紫
外吸收的成分均有良好的分离,一次进样同时测定了两类不同成分的指纹图谱,不同批次间的相似度符合相关
规定。 [结论] 该方法可用于丹芪偏瘫胶囊中间体中两类不同成分指纹图谱的同时测定。

Abstract: [Objective] To establish the HPLC/DAD/ELSD fingerprint of Danqi Capsule for hemiplegia
for the full scientific control of Danqi capsule hemiplegia and to provide a new method for the quality
control. [Methods] The technique in series of HPLC/DAD/ELSD was applied. Waters Bridge, RP18
