目的：建立了阳光胶囊中淫羊藿苷含量的测定方法。方法：采用固相萃取与高效液相色谱法结合的分析技术，样品供试液用Ｓｅｐ－ＰａｋＣ１８微柱制备，用十八烷基硅统健合硅胶为固定相，６０％甲醇水为流动相，紫外检测，进行了线性范围、精密度、稳定性、加样回收试验。结果：平均回收率为９９．６％，ＲＳＤ为１．８％。结论：该法简便、高效、分析结果准确、可靠，适宜于本品的质量控制。
Objective: To establish a method for the determination of icariin content in sun capsules. Methods: Analytical techniques using solid-phase extraction combined with high performance liquid chromatography (HPLC) were used. The sample solution was prepared using Sep-Pak C18 microcolumn. Silica-octane-silicon-based silica gel was used as the stationary phase and 60% methanol water was used as the mobile phase. , UV detection, linear range, precision, stability, sample recovery test. Results: The average recovery was 99.6% with an RSD of 1.8%. Conclusion: This method is simple, efficient, accurate and reliable, and suitable for the quality control of this product.
