摘要
目的:建立同时测定羊藿三七胶囊中朝藿定C和淫羊藿苷含量的高效液相色谱法。方法:采用Agilent C18柱(150 mm×4.6 mm,5μm);流动相为乙腈-0.05%磷酸溶液(26∶74);流速为1.0 m L·min^-1;检测波长为270 nm。结果:朝藿定C进样量在0.288-9.198μg、淫羊藿苷进样量在0.111-3.558μg与峰面积呈良好的线性关系(r=0.999 9);朝藿定C的平均回收率为103.0%,RSD=0.8%(n=6);淫羊藿苷的平均回收率为98.9%,RSD=1.8%(n=6)。结论:本方法简便、准确,重复性好,可作为羊藿三七胶囊中淫羊藿的含量测定方法。
Objective:To establish a HPLC method for simultaneous determination of epimedin C and icariin in Yanghuo Sanqi Capsules.Methods:The samples were separated on Agilent C18 column( 150 mm × 4.6 mm,5 μm) by acetonitrile-0.05% phosphoric acid solution( 26 ∶ 74) as the mobile phase.The flow rate was 1.0 m L·min^- 1and the detection wavelength was 270 nm.Results:The calibration curves showed good linearity in the range of 0.288-9.198 μg( epimedin C),0.111-3.558 μg( icariin).The average recoverise( n = 6) were 103.0%( RSD = 0.8%),98.9%( RSD = 1.8%),respectively.Conclusion:The method is simple and accurate with good reproducibility.It can be used for the determination of Epimedii Folium in Yanghuo Sanqi Capsules.
