摘 要: | 目的:用高效液相色谱法测定非布司他片的有关物质。方法:采用TSKgel ODS-80Ts色谱柱(4.6mm×250mm,5μm),以0.02%冰醋酸溶液为流动相A,0.02%冰醋酸乙腈溶液为流动相B梯度洗脱,流量1.0mL·min^-1,检测波长217am。可采用杂质对照品法或加校正因子的自身对照法测定有关物质。结果:浓度分别在1.021~3.063μg·mL^-1(r=0.99994);1.002—3.006μg·mL^-1(r=0.99995);0.993~2.979μg·mL^-1(r=0.99997)范围内与峰面积呈良好的线性关系,主药与有关物质能达到较好的基线分离。结论:本方法灵敏度高,专属性强,准确可靠,可用于该药品质量控制。

Abstract: | Objective: To establish an HPLC method for determination of related substances of febuxostat tablets. Methods: The TSKgel ODS-80Ts (4. 6 mm ×250 mm,5μm)was used, Using gradient elution,and the flow rate was 1.0 mL μ min^-1. The detection wave-length was 217 nm. Results: The linear ranges were 1. 021-3.063 μg · mL^ - 1 ( r = 0. 999 94 ) ; 1. 002-3. 006μg · mL^ - 1 ( r = 0. 999 95 ) and 0. 993-2. 979μg · mL^-1 (r =0. 999 97), the related substances and febuxostat could be separated well. Conculsion: The method was sensitive, accurate and high specific for the quality evaluation and control. |
