摘要： A high performance liquid chromatography-tandem mass spectrometric method had been established for simultaneous determination of 25 sex hormones. The hormones were extracted by ethyl acetate and ethyl acetate-tert-butyl methyl ether (1/1, v/v) after enzymatic hydrolysis, followed by an LC-C18 cartridge for cleanup, then were quantified by HPLC-ESI MS/MS with internal standards. Limits of quantification were 1-2 mu g.kg(-1), average recoveries were 92-113 %, and the R.S.D. was 6-10 %.
