TITLE: | |
摘要: | 目的:建立测定比沙可啶肠溶片含量及含量均匀度的方法。方法:采用高效液相色谱法。色谱柱为Agilent ZORBAX C18,流动相为乙腈-20 mmol/L乙酸铵溶液(冰醋酸调pH至5.0)(55 ∶ 45,V/V),检测波长为265 nm,柱温为30 ℃,流速为1.0 ml/min,进样量为20 μl。结果:比沙可啶检测质量浓度线性范围为50~1 000 μg/ml(r=0.999 9);精密度、稳定性、重复性试验的RSD<1%;回收率为99.50%~101.17%,RSD=0.5%(n=9)。结论:该方法重复性好、准确度高,适用于比沙可啶肠溶片的质量控制。 |
ABSTRACT: | OBJECTIVE: To establish a method for the determination of content and content uniformity in Bisacodyl enteric-coated tablet. METHODS: HPLC method was performed on the column of Agilent ZORBAX C18 with mobile phase of acetonitrile-20 mmol/L ammonium acetate (adjusted pH to 5.0 with acetic acid) (55 ∶ 45,V/V), the detection wavelength was 265 nm, column temperature was 30 ℃, flow rate was 1.0 ml/min, and the volume injection was 20 μl. RESULTS: The linear range of bisacodyl was 50-1 000 μg/ml(r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 1%; recovery was 99.50%-101.17%(RSD=0.5%,n=9). CONCLUSIONS: The method is reproducible with high accuracy, and suitable for the quality control of Bisacodyl enteric-coated tablet. |
