Abstract

An analytical method has been developed in order to control the illegal use of stanozolol as growth promoter in livestock. The procedure was based on enzymatic hydrolysis, purification on a Clean Screen DAU column and derivatization with heptafluorobutyric anhydride prior to GC-MS analysis. This method allowed us to study the metabolism of stanozolol in cattle after oral and subcutaneous administrations. Urinary metabolites were identified by mass spectrometry. Stanozolol and 16-hydroxystanozolol were detected after oral administration, while 16-hydroxystanozolol and 4,16-dihydroxystanozolol were found after subcutaneous administration.
