摘 要:
目的 建立淫黄胶囊中淫羊藿苷的含量测定方法。方法 采用高效液相色谱法。色谱柱为Zorbax SB—C18(250mm×4.6mm,5μm);流动相为乙腈-水(25:75,V/V),流速1.0mL/min;检测波长270nm。结果 淫羊藿苷的进样量与其峰面积积分值在0.09984~0.59904μg范围内有良好的线性关系(r=0.9998),平均加样回收率为97.77%,RSD=1.77%(n=6)。结论 本法简便可行,准确可靠,可用于淫黄胶囊中淫羊藿苷的含量测定。[著者文摘]

Abstract:
Objective To establish an HPLC method for determination of the content of icariin in Yinhuang Capsules. Methods The HPLC assay was performed on a Zorbax SB-CIs column (250 mm× 4.6 mm, 5 μm) with the mobile phase of acetonitrile-aquous (25 : 75, V/V) at a flow rate of 1.0 mL/min, and the detective wavelength was 270 nm. Results A good linearity of icariin was obtained in the range of 0.099 84~0.599 04μg (r=0.999 8). The average recovery was 97.77% and RSD was 1.77% (n =6). The method is simple, feasible, accurate and reliable. It can be applied to the determination of icariin in Yinhuang Capsules.[著者文摘]
