Diethylstilbestrol and bisphenol A were extracted from food products using acetonitrile by QuEChERS method. Additional purification and concentration of the extract was performed by dispersive liquid-liquid microextraction using trichloromethane. Run time is 1-1,5 hours, relative standard deviation of test results is not higher than 0,1. Key words : diethylstilbestrol, bisphenol A, gas liquid chromatography, electron capture detector, trifluorouracil derivatives, QuEChERS method, dispersive liquid-liquid microextraction Электронная Научная СельскоХозяйственная Библиотека
