Keyword:  复胃散胶囊黄芪甲苷高效液相色谱-蒸发光散射;
Abstract: 目的 建立高效液相色谱-蒸发光散射检测器法测定复胃散胶囊中黄芪甲苷的含量.方法 采用Agilent 1200高效液相色谱仪和Waters Xselect C18色谱柱(4.6 mm×250 mm,5μm),流动相为乙腈-水(32:68),流速为1.0 mL·min-1,进样量为20μL,蒸发光散射检测器(漂移管温度为70℃,载气流速为2.0 L·min-1).结果 黄芪甲苷在0.0505~1.011 mg·mL-1的范围内呈良好的线性关系,标准曲线为lgA=1.3555lgC+3.2776(r=0.999);精密度和重复性的RSD分别为1.2%和1.6%;平均回收率为96.1%,RSD为1.7%.结论 该方法简便准确、快速、方便、精密度高、重复性好,可用于复胃散胶囊中黄芪甲苷的含量测定.
