Abstract
The stability of and Boldenone glucuronides (BOLg), Testosterone glucuronide (Tg) and Epitestosterone glucuronide (ETg) in bovine faeces was studied in vitro. The detection of the glucuronide steroids, added to saline sospensions of faeces, and of the respective free forms, was performed by HPLC-MS/MS in positive APCI mode. The results show that Tg and BOLg, as previously observed for the free forms, resulted poorly stable; α Bolg and ETg transformed mainly into α Boldenone (α Bol) and Epitestosterone (ET). Neo formations of α Bol and ET were also confirmed.
