| 摘 要： | 本文用GC/MS方法,对人尿中脱氢睾酮(boldenone)代谢物进行了研究。志愿者口服20 mg脱氢睾酮后,收集阳性尿。尿样经过包括XAD-2树脂柱吸附、酶水解、有机相萃取及三甲基硅烷衍生化反应的预处理后,用毛细管气相色谱与质谱检测器联用进行分析,鉴定了脱氢睾酮的几个主要代谢物和它们的代谢模式;总结了兴奋剂检测中具有意义的代谢物及其碎片离子;对收集的阳性尿中脱氢睾酮浓度进行测定;对预处理方法的回收率进行了研究。

| Abstract: | The metabolism of boldenone (17 beta-hydroxy-1,4-androstem-3-one) in man has been investigated by gas chromatography/mass spectrometry. After oral administration of a 20 mg dose to man, six metabolites were detected in the conjugated fraction of the urinary samples. Boldenone, the major compound excreted in urine, was detected within 34 h after administration. In addition, several metabolites, resulting from the hydroxylation of boldenone and the reduction of the unsaturated carbon bonds of boldenone, were detected in the urine samples varying from 9 to 83 h. Extraction and fractionation of these metabolites were achieved by using XAD-2 column and gas chromatography. The recovery of the whole procedure was studied. Furthermore, the mass spectra of the metabolites are presented and major fragment pathways are discussed. |
