Abstract:Objective:To establish a RP- HPLC method for determination of salicyhc acid in its lotion . Method:Chromatographic condition included Hypersil ODS column and mobile phase of a mixture of methanol - water ( 80 : 20 ) , the detection wavelength was 283 nm.Results: The linear ranges of salicylic acid was 3.19ug/ ml-31.9ug/ml( r = 0.9998 ) ; the average recoveriy was 100.5% (RSD =0.54%) ( n=9 ). Conclusion:This method is simple, accurate, sensitive, and can be used for the quality control of the preparation.
Keywords:Salicylic acid  HPLC
