Take ammonium acetic acid with methanol solution as mobile phase,under the conditions that ultraviolet detector wavelength of 256 nm and the column temperature of 35 ℃,an HPLC method for detecting the content of Propyl p-Hydroxybenzoate in soy sauce and vinegar is established.The result shows that the method has a good linear relationship and the correlation coefficient is 0.9989 with the limit of detection of 1 mg/L.The average recoveries vary from 104% to 118% with the relative standard deviation of 0.89%.The comparative study with the local standard method proves that the two methods are basically identical. It is suitable for the detection of Propyl p-hydroxybenzoate (PP)in soy sauce and vinegar.
