TI  - [Determination of 41 hormones in cereal feeds by liquid chromatography-tandem 
      mass spectrometry].
PG  - 523-34
AB  - A method was developed for the determination of 10 androgens, 11 progesterones, 
      10 glucocorticoids, 5 estrogens and 5 resorcylic acid lactones in cereal feeds by 
      liquid chromatography-tandem mass spectrometry (LC-MS/MS). Ethyl acetate was used 
      to extract the sample, and the mixed QuEChERS sorbents were dispersed for 
      purification. The extract was separated by a C18 column and detected in positive 
      or negative multiple reaction monitoring (MRM) mode. With the optimal conditions, 
      the linear ranges of 41 hormones were 5.0 - 200.0 microg/kg with the correlation 
      coefficients above 0.99 and the limits of quantification (LOQs, S/N > or = 10) 
      were 0.123- 2.72 microg/kg. The method validation was carried out at three 
      spiking levels, and the recoveries were 70.3% - 118.1% for soybean meals with the 
      relative standard deviations (RSDs) of 0.82% - 19.5%, and 76.1% - 122.8% for corn 
      meals with the RSD of 1.3% - 15.0%. This method is simple, fast and credible, can 
      be applied to simultaneous screening and determination of estrogens, 
      progesterones, androgens, glucocorticoids and resorcylic acid lactones belonging 
      to the illegal additive of hormones in cereal feeds.
