Abstract:

The method for determination of diethylstilbestrol (DES) residues in aquatic products by UPLC-MS/MS was developed. The DES residues were extracted with ethyl acetate, purified with SLH solid phase extraction cartridge, determined by UPLC-MS/MS and quantified by external standard method. When adding diethylstilbestrol to samples in a range of 0.1 to 1.0 μg/kg, the recoveries are above 75%, the relative standard deviations are between 5.5% and 9.2%.

Key words: UPLC-MS/MS, diethylstilbestrol, aquatic products
