液相-蒸发光散射检测法测定龙生蛭胶囊中黄芪甲苷的含量。方法色谱柱为Diamonsil C18(250mm×4.6 mm,5μm)。流动相为乙腈-水(33∶67),流速1.0 ml/min。ELSD参数:漂移管温度105℃,气体流量2.8 ml/min。结果黄芪甲苷在2.45~10.64μg的线性关系良好(r=0.999 2,n=5)。结论方法简便准确,重现性好,灵敏度高。 更多还原
【Abstract】 Objective To establish an HPLC-ELSD method for determining the contents of astragaloside in Longshengzhi capsules.Methods The chromatographic column was Diamosil C18(250 mn×4.6 mm,5 μm).The mobile phase was ace tonitrile-water(33∶67)and the flow rate was 1.0 ml/min.The drift tube temperature was at 105℃.The gas flow rate was at 2.8 ml/min.Results Within the range of 2.45~10.64 μg,the content of astragaloside had a good linear ratationship(r=0.999 2,n=5).Conclusion The method is easy,reliable,sen... 更多还原
