Abstract
ObjectiveTo establish a method for content determination of triamcinolone acetonide acetate in triamcinolone acetonide and neomycin paste by HPLC.Methods The experimental condition of the RP-HPLC method was as follows:DIONEX Acclaim 120 C18(250mm×4.6mm,5μm),with linear gradient elution using methanol and water (60∶40),The detected wavelength was 240 nm,the flow rate was 1.0 ml/min,The column temperature was at 30℃. ResultsThe fluocinolone acetonide curve was linear in the range of 0.05~0.50μg(r=0.9999).The average recovery rate was 98.09% withRSD of 0.73%.ConclusionThe method is simple,reliable,accurate and It could be used in the determination of triamcinolone acetonide acetate in triamcinolone acetonide and neomyc in paste.关键词
