Discovery of a novel glucuronide metabolite of methyltestosteron in tilapia bile e in tilapia bile by liquid chromatography/quadrupole-time of flight mass spectrometry

摘要

1. A new hydroxylated MT glucuronide was detected in bile up to 14 days. 2. The hydroxylation is not at C-6, C-7, C-11 or C-19 position. 3. The hydroxylation is most probably in the D ring.
