目的:建立高效液相色谱法测定乳病消片中淫羊藿苷的含量。方法:色谱柱:Luna C_(18)柱(250 mm×4.60 mm,5μm),流动相:乙腈-水(30:70),流速:1.0 ml·min~(-1),柱温:30℃,检测波长:270 nm。结果:淫羊藿苷在20~80μg·ml~(-1)的浓度范围内呈良好的线性关系(r=0.999 9,n=7),平均加样回收率为98.15%(RSD=0.73%)。结论:本方法简便、准确、重复性好,可用于乳病消片的质量控制。
Objective: To establish an HPLC method for the determination of icariin in Ruxiaoxiao Tablet. Methods: The mobile phase consisted of Luna C 18 column (250 mm × 4.60 mm, 5 μm), mobile phase of acetonitrile-water (30:70), flow rate of 1.0 ml · min -1 and column temperature of 30 ℃ , Detection wavelength: 270 nm. Results: Icariin showed a good linear relationship (r = 0.999 9, n = 7) in the range of 20-80 μg · ml -1 with an average recovery of 98.15% (RSD = 0.73% ). Conclusion: The method is simple, accurate and reproducible, and can be used for the quality control of Xiaobuxiao tablets.
