TITLE:
摘要: 目的:建立测定利心丸中毛蕊花糖苷含量的方法。方法:采用高效液相色谱法。色谱柱为ZORBAX SB-Aq,流动相为乙腈-0.1%磷酸溶液(16 ∶ 84,V/V),流速为1.0 ml/min,检测波长为334 nm,柱温为30 ℃,进样量为10 μl。结果:毛蕊花糖苷检测进样量线性范围为0.254 4~1.526 4 μg(r=0.999 7);定量限为1.358 6 μg/ml,检测限为0.407 6 μg/ml;精密度、稳定性、重复性试验的RSD<2%;加样回收率为95.06%~97.31%(RSD=1.05%,n=6)。结论:该方法操作简便、结果准确,适用于测定利心丸中毛蕊花糖苷的含量。
ABSTRACT: OBJECTIVE: To establish a method for the content determination of verbascoside in Lixin pill. METHODS: HPLC was performed on the column of ZORBAX SB-Aq with mobile phase of acetonitrile-1% phosphoric acid solution (16 ∶ 84,V/V) at a flow rate of 1.0 ml/min, detection wavelength was 334 nm, column temperature was 30℃, and injection volume was 10 μl. RESULTS: The linear range of verbascoside was 0.254 4-1.526 4 μg(r=0.999 7); limit of quantification was 1.358 6 μg/ml, and limit of detection was 0.407 6 μg/ml; RSDs of precision, stability and reproducibility tests were lower than 2%; recovery was 95.06%-97.31%(RSD=1.05%,n=6). CONCLUSIONS: The method is simple, accurate, and suitable for the content determination of verbascoside in Lixin pill.
