摘  要:
建立参松养心胶囊中人参皂苷Rb1含量测定的HPLC方法。色谱柱Alltima C18(250mm×4.6mm,5μm),流动相乙腈-0.02%磷酸水溶液(32∶68),流速1.0mL/min;检测波长203nm。人参皂苷Rb1进样量在0.4~4.0μg与峰面积呈良好线性关系(r=0.999 1);平均加样回收率100.3%,RSD 1.72%。本方法结果准确,精密度及重现性较好,可以用于参松养心胶囊中人参皂苷Rb1的含量测定。

摘  要:
To develop an HPLC method for determination of active ginsenoside Rb1 in Shensongyangxin Capsules.Chromatographic separation was performed on an Alltima C18(250mm×4.6mm,5μm)column;mobile phase was acetonitrile-0.02% phosphoric acid,flow rate was 1.0mL/min;detector wavelength was 203nm.Good linear relationships of ginsenoside Rb1 was provided over investigated concentration between 0.4-4.0μg(r=0.999 1).The average recoveries of ginsenoside Rb1 was 100.3%.Repeatability experiments showed that relative standard deviation(RSD) values of ginsenoside Rb1 was 1.72%.The developed method was acurate,sensitive and repeatable,and can be used for the determination of ginsenoside Rb1 in Shensongyangxin Capsules.
