摘要
目的:用HPLC-ELSD法对蒺藜皂苷元进行含量测定。方法:用HPLC-ELSD法测蒺藜中的含量进行测定,色谱条件ODS柱(5μm,250mm×4.6mm),流动相:乙腈-水(97:3,V/V)。结果:蒺藜皂苷元在0.83-4.98μg呈良好的线性关系(r=0.9993,n=5),平均回收率为99.8%(n=9),RSD为1.30%。结论:本方法简便易行,适用于蒺藜的含量测定。
Objective:An HPLC-ELSD method was established for determination of terrestris saponin. Methods:ODS column(5μm,250mm×4.6mm)and evaporative light scattering detector(ELSD) were used. Acetonitrile-water(97:3, V/V)were used as mobile phase.Results:There was a good linear relationship (r=0.9993,n=5)when terrestris saponin was 0.83~4.98μg.The average recovery rate was 99.8% and RSD was 1.30%.Conclusion:The method was simple and accurate.It could be used for the determination of terrestris saponin.
