论文标题: HPLC法测定洛伐他汀分散片的含量及含量均匀度
英文标题:
中文摘要: 目的:建立测定洛伐他汀分散片含量及含量均匀度的方法,为其仿制生产和贮存期质量控制提供参考。方法:采用高效液相色谱法。色谱柱为Waters MS C18,流动相为乙腈-0.01%磷酸(55 ∶ 45,V/V),检测波长为238 nm,柱温为30 ℃,流速为1.0 ml/min,进样量为20 μl。结果:洛伐他汀检测质量浓度线性范围为20.32~609.60 μg/ml(r=0.999 9);精密度、稳定性、重复性试验的RSD<1%;回收率为99.60%~101.68%,RSD=0.8%(n=9)。结论:该方法的重复性好、准确度高,适于洛伐他汀分散片的质量控制。
英文摘要: OBJECTIVE:To establish a method for the determination of content and content uniformity in Lovastatin dispersible tablet,to provide reference for the quality control of its peneric production and storage period. METHODS: HPLC method was adopted on the column of Waters MS C18 with mobile phase of acetonitrile-0.01% phosphoric acid (55 ∶ 45,V/V), detection wavelength was 238 nm, column temperature was 30 ℃, flow rate was 1.0 ml/min, and the volume injection was 20 μl. RESULTS: The linear range of lovastatin was 20.32-609.60 μg/ml (r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 1%; recovery was 99.60%-101.68% (RSD=0.8%,n=9). CONCLUSIONS: The method is reproducible with high accuracy, and suitable for the quality control of Lovastatin dispersible tablet.
