Abstract
An analytical method has been developed in order to control the illega l use of stanozolol as growth promoter in livestock. The procedure was based on enzymatic hydrolysis, purification on a Clean Screen DAU col umn and derivatization with heptafluorobutyric anhydride prior to GC-M S analysis. This method allowed us to study the metabolism of stanozol ol in cattle after oral and subcutaneous administrations. Urinary meta bolites were identified by mass spectrometry. Stanozolol and 16-hydrox ystanozolol were detected after oral administration, while 16-hydroxys tanozolol and 4,16-dihydroxystanozolol were found after subcutaneous a dministration.
