摘要: 目的 建立用紫外分光光度法测定洛索洛芬钠片含量的方法。方法 以水为溶剂,测定波长为223nm。结果 检测线性范围为4.01616.064μg/mL,r=0.9997。平均回收率为98.81%,RSD=1.19%。结论 本方法准确、快速、简便,可用于洛索洛芬钠片的质量控制。Abstract: Objective To establish an UV spectrophotometry method to determine the contents of loxoprofen sodium tablets. Methods The water was used as solvent. The detection wavelength was set at 223nm. Results The calibration curve was linear in the range from 4.016 to 16.064μg/mL, r=0.9997. The average recovery was 98.81% and the RSD was 1.29%(n=5). Conclusion The method is accurate, rapid and simple for the quality control of loxoprofen sodium tablets.
