Determination of Tyrosine in Urine Spectrophotometric Method;2. For chemical pre-extraction, MSTFA/TMSL derivatization reaction, GC/MS analysis, it is confirmed that two main metabolites (19-no-randrosterone and 19-noretiocholanolone) were found in nandrolone urine.

本文对合成的19-去甲雄烷醇酮的四个差向异构体混合物进行气相色谱分离，对诺龙和炔诺酮用药后，留取的人尿样通过化学预处理，MSTFA/TMSI衍生化反应，GC/MS分析，确证了尿样中诺龙的两个主要代谢产物为19-去甲雄酮和19-去甲原胆烷醇酮，炔诺酮的两个主要代谢物是四氢炔诺酮的两个形式，可能是3α-OH-5α-THINE和3α-OH-5β-THINE，在炔诺酮代谢前期，还发现有诺龙的上述两个代谢物存在。
