Abstract:
OBJECTIVE:To establish a method for the content determination of loxoprofen silver in Loxoprofen silver cream, and provide reference for the quality control of the preparation. METHODS:HPLC was performed on the column of Diamonsil C18 with mobile phase of methanol-water-glacial acetic acid-triethylamine(55:45:0.1:0.1,V/V/V/V)at a flow rate of 1.0 mL/min,de-tection wavelength was 223 nm,column temperature was 30 ℃,and the injection volume was 20 μL. RESULTS:The linear range of loxoprofen silver was 6.53-130.7μg/mL(r=0.9999);the limit of quantitation was 0.253μg/mL,limit of detection was 0.076μg/mL;RSDs of precision,stability and reproducibility tests were lower than 2%;recovery was 96.79%-103.68%(RSD=2.23%, n=9). CONCLUSIONS:The method is simple,accurate and reproducible,and can be used for the content determination of Loxo-profen silver cream.
