摘要
目的建立测定康艾扶正颗粒中黄芪甲苷含量的HPLC-ELSD法。方法采用HPLC-ELSD法,pilenomene×Luna 5u C18色谱柱(150mm×4.60mm,5μm),以乙腈-水(34:66)为流动相,流速:1.0ml·min^-1。ELSD参数:漂移管温度110℃,气体流速2.8L·min^-1。结果在选择的色谱条件下黄芪甲苷与其它组分分离良好,对照品在2.064~10.32μg范围内呈良好的线性关系(r=0.9999),平均回收率为100.48%,RSD为1.06%。结论HPLC-ELSD法可用于康艾扶正颗粒中黄芪甲苷含量测定。
Aim A HPLC-ELSD method was developed for the quantitative determination of astragaloside Ivin Kangai Fuzheng Granules. Methods Astragaloside Ⅳ concentration was detected by using high performance evaporative light scattering detection The chromatographic conditions adopted were:phenomenne × Luna-C18 column( 150 mm ×4.60 mm, 5 μm) ,a mobile phase of acetonitrile-water(34: 66) ,room temperature of the drift tube was set at 110℃ ,and the flow rate of nebulizing gas at 2.8 L · min^-1. Results The alibration curves for the quantitative determination of astragaloside IV was linear over the range of 2.064 - 10. 32 μg (r = 0. 9999). The recovery was 100. 48% with RSD 1.06 %. Conclusion The developed method can be used for the quantitative determination of stragaloside Ⅳ in kanghi fuzheng granules.
