Application of Pressurized Capillary Electromatography in Detection of Geniposide and Baicalin in Xiongju Shangqing Pian[J]. 2015,34(10):1147-1151.
采用加压毛细管反相电色谱技术,建立了一种用于分离检测芎菊上清片中栀子苷和黄芩苷的高效简便新方法。色谱柱为EP-100-20/45-3 C18毛细管柱(总长度45 cm,有效长度20 cm,直径为100 μm,ODS填料内径3 μm),柱温为25 ℃,流动相采用20 mmol/L NaH2PO4-乙腈(71∶29),流动相的总流速为0.035 mL/min,分离电压为+2.0 kV,检测波长为240 nm。经等度洗脱,栀子苷和黄芩苷可实现快速分离,峰面积的相对标准偏差(RSD)不大于2.8%,回收率为91.9%~101.2%,测得该芎菊上清片中栀子苷的含量为2.616 mg/g,黄芩苷的含量为11.220 mg/g。该方法的选择性好、柱效高、试剂用量少,用于芎菊上清片中黄芩苷和栀子苷的分离检测,结果满意。
A high performance and facile method was developed for analysis of geniposide and baicalin by reversed-phase pressurized capillary electromatography(pCEC).The separation was performed on a reversed-phase EP-100-20/45-3-C18 column(total length 45 cm,effective length 20 cm,diameter 100 μm,ODS packing inside diameter 3 μm) with column temperature of 25 ℃.The mobile phase was composed of 20 mmol/L NaH2PO4-acetonitrile(71∶29), mobile phase overall flow rate was set at 0.035 mL/min,separation voltage was +2.0 kV,and the UV detection wavelength was 240 nm.In an isocratic mode pCEC,the relative standard deviations(RSDs) for peak area were not more than 2.8%,and the recoveries were in the range of 91.9%-101.2%.This method was applied in the detection of Xiongju Shangqing Pian with geniposide content of 2.616 mg/g and baicalin content of 11.220 mg/g.The method showed advantages of good selectivity,high column efficiency and low consumption of sample and reagent,and was successfully applied in the separation and detection of geniposide and baicalin in real sample.
