高效液相色谱法测定三七伤药片中3组分的含量

目的建立以高效液相色谱法测定三七伤药片中三七皂苷R1和人参皂苷Rg1、Rb1含量的方法。方法色谱柱为VP-ODS(150mm×4.6mm,5μm),使用梯度洗脱系统,流动相为乙腈-水(0~20min(20∶80),20~26min(40∶60),26~35min(20∶80)),流速为1.0mL.min-1,柱温为室温,检测波长为203nm。结果三七皂苷R1的线性范围为0.261~7.83μg(r=0.9999),平均回收率为(101.12±2.03)%(RSD=2.1%);人参皂苷Rg1的线性范围为0.6025~18.075μg(r=0.9997),平均回收率为(97.22±3.33)%(RSD=1.9%);人参皂苷Rb1的线性范围为0.5375~16.125μg(r=0.9996),平均回收率为(100.71±2.4)%(RSD=1.6%)。结论该法可用于测定三七伤药片中三七皂苷R1、人参皂苷Rg1、Rb1的含量。

Determination of Notoginsenoside R1, Ginsenoside Rg1 and Rb1 in Sanqishangyao Tablets by HPLC

OBJECTIVE:To set up a HPLC method for the determination of the contents of notoginsenoside R1,ginsenoside Rg1 and Rb1 in Sanqishangyao tablets.METHODS:It was performed on VP-ODS (150mm×4.6mm,5μm),and the mobile phase was acetonitrile-water with gradient elution system(0～20min(20∶80),20～26min(40∶60),26～35min(20∶80)).The flow rate was 1.0mL·min-1 and the column temperature was room temperature.The detection wavelength was 203nm.RESULTS:The liner range of notoginsenoside R1 was 0.261～7.83μg(r=0.999 9)and the average recovery was (101.12±2.03)%(RSD=2.1%).The liner range of ginsenoside Rg1 was 0.602 5～18.075μg(r=0.999 7)and the average recovery rate was (97.22±3.33)%(RSD=1.9%).The liner range of ginsenoside Rb1 was 0.537 5～16.125μg(r=0.999 6)and the average recovery rate was(100.71±2.4)%(RSD=1.6%).CONCLUSION:The method is suitable for the content determination of notoginsenoside R1,ginsenoside Rg1 and Rb1 in Sanqishangyao Tablets.
