Abstract: Objective To establish the quantitative determination method of dexamethasone acetate in Kelaweiding liniment by HPLC. Methods Column:Diamonsil-C18(150 mm×4.6 mm,5 μm),mobile phase:methanol-water-glacialaceticacid (80:20:0.5),flow rate:1.0 ml/min,UV detection wavelength:240 nm,injection volume :20 μl,column temperature:30℃. Results The standard curve was linear within the range of 2.00-64.00 μg/ml,linear equation was Y=0.405 2X+0.804 2(r=0.999 9).The average recovery was 99.3% with RSD 0.93% (n=9). Conclusion This method was simple,stable and could be used to assay dexamethasone acetate in Kelaweiding liniment.
