An analytical method to determine 2 preservatives in preserved vegetables such as p-hydroxybenzoic acid esters(ethyl paraben and propyl paraben)by a capillary gas chromatography was studied.The results showed that the recovery was ranged between 88%~97% and the relative standard deviations were ranged between 1.8%~5.0%.This method is accurate and simple.
