Abstract

A sensitive method for the quantitation of oxandrolone in urine was developed using GC/MS. After oral administration of 10mg oxandrolone, oxandrolone excreted in urine as unchanged form was extracted in ether and derivatized to its O-TMS. Oxandrolone excreted in urine as glucuronide conjugated form was extracted after enzymatic hydrolysis and derivatized to its O-TMS. The amounts of oxandrolone-O-TMS was measured in GC/MS with selected ion monitoring. Calusterone, a structurally similar anabolic steroid, was employed as internal standard.
