| Abstract: | A method was described for determination of salicylic acid in flavor and essence by HPLC with DAD on DIAMONSIL Cls column. The absorbance of samples were linear to the amount of salicylic acid between 0.2 - 50 mg/L, with the correlative coefficient of 0.9997, the recoveries range 96.50%-99.71%, and relative standard deviation was 0.16 %. The resuits indicated that the method was simple, rapid and reproducible, reliable for salicylic acid detection. |
