摘要：
We have developed a liquid chromatography tandem mass spectrometric (LC-MS/MS) method for the simultaneous quantitative analysis of several free forms of steroid hormones in bovine serum I pregnenolone (P-5), progesterone (P-4), 17hydroxyP(5), 17hydroxyP(4), testosterone (T), dehydroepiandrosterone (DHEA), androstenedione (A), estrone (E-1), 2,4 and 16 hydroxyE(1), 2 and 4 methoxyE(1)]. Deuterated analogs were used as internal standards. Serum proteins were eliminated with acetonitrile. Oxime derivatives of steroids were extracted with tert-butylmethylether and analyzed in positive MRM mode. Methodology was validated in accordance with the European Commission Decision 2002/657/EC. Performance characteristics permit the use of this methodology for steroid determination in animal serum samples. (C) 2009 Elsevier B.V. All rights reserved
