摘  要:目的:建立测定肾王膏中淫羊藿苷含量的方法。方法:采用高效液相色谱法。色谱柱为Chromasil C18(250mm×4.6mm,5μm),流动相为乙腈-0.5%磷酸溶液(27:73,V/V),流速为1.0ml/min,柱温为30℃,检测波长为270nm。结果:淫羊藿苷的进样量在0.0905~0.3620μg范围内与峰面积积分值呈良好的线性关系(r=0.9998);精密度、稳定性、重复性试验的RSD〈3%;平均加样回收率为101.24%,RSD=1.25%(n=9)。结论:该方法简便、快速、重复性好,可用于肾王膏的质量控制。OBJECTIVE: To establish the method for content determination of icariin in Shenwang cream. METHODS: HPLC method was used. The determination was performed on Chromasil C18(250×4.6mm,5μm) column with mobile phase consisted of acetoneitrile-5% phosphoric acid (27:73, V/V) at the flow rate of 1.0 ml/min. The column temperature was 30℃, and detection wavelength was set at 270 nm. RESULTS: The liner range of icariin was 0.090 5-0.362 0μg(r=0.999 8). RSD of precision, stability and reproducibility tests were lower than 3% with an average recovery of 101.24% (RSD=1.25%, n=9). CONCLUSIONS: The method is simple, rapid and repeatable. It can be used for quality control of Shenwang cream.
