论文标题: HPLC法测定抗骨质增生片中淫羊藿苷的含量
英文标题:
中文摘要: 目的:建立测定抗骨质增生片中淫羊藿苷含量的方法,以期为完善该制剂的质量标准提供依据。方法:采用高效液相色谱法。色谱柱为Hypersil ODS2 C18,流动相为乙腈-水(27 ∶ 73,V/V),流速为1.0 ml/min,检测波长为270 nm,柱温为25 ℃,进样量为10 μl。结果:淫羊藿苷检测质量浓度线性范围为3~60 μg/ml(r=0.999 9);定量限为11.2 μg/ml,检测限为4.3 μg/ml;精密度、稳定性、重复性试验的RSD<2.0%;加样回收率为99.00%~100.67%(RSD=0.63%,n=6)。结论:该方法操作简便、结果准确、重复性好,可用于测定抗骨质增生片中淫羊藿苷的含量。
英文摘要: OBJECTIVE: To establish a method for the content determination of icariin in Kangguzhi zengsheng tablet,and provide a basis for improving the quality standard. METHODS: HPLC was performed on the column of Hypersil ODS2 C18 with mobile phase of acetonitrile - water (27 ∶ 73,V/V) at a flow rate of 1.0 ml/min, detection wavelength was 270 nm, column temperature was 25 ℃, and injection volume was 10 μl. RESULTS: The linear range of icariin was 3-60 μg/ml (r=0.999 9); limit of quantitation was 11.2 μg/ml, limit of detection 4.3 μg/ml; RSDs of precision, stability and reproducibility tests were lower than 2.0%; recovery was 99.00%-100.67%(RSD=0.63%, n=6). CONCLUSIONS: The method is simple, accurate and reproducible, and can be used for the content determination of icariin in Kangguzhi zengsheng tablet.
