| Abstract: | Objective： To establish ultraviolet spectrophtometry method for the determination of loxoprofen sodium. Methods： The contents of loxoprofen sodium were determined at 223 nm with water as the blank control by ultraviolet spectrophotometry. Results： The calibration curve of loxoprofen sodium was linear when its concentration range was from 4.016 to 20.080 μg/ml（r=0.999 4,n=5）, and average recovery was 99.13%. Conclusion： The method is convenient in operation, precise, reliable in results,and can be used as rapid determination for loxoprofen sodium in tablets. |
