Abstract

In this paper, the GEs were detected by liquid chromatography- mass spectrometry. This method had been optimized the pretreatment conditions and the mobile phase gradient elution program based on the AOCS.The recovery values of GEs ranged from 92.42% to 109.20%, meanwhile the RSD was 4.01% to 7.52%. The minimum detection limit of five GEs ranged from 9μg /kg to 30μg /kg.This method had high sensitivity and good repeatability.This method can meet the need of content analysis of glycidyl ester in practical work.
