title: Detection of benzoylecgonine in human urine.
abstract: A thin-layer chromatography (TLC) method is described that can be used to detect benzoylecgonine (BE), a metabolite of cocaine, in human urine. It is a two-part procedure that can be integrated into a rapid screening program for drug abuse. The first part of the method utilizes two TLC solvent systems to identify a variety of drugs, including BE. The second part is specific for the cocaine metabolite and can be used as a confirmation method. The procedure is sensitive to 3-4 microgram/ml of BE in urine.
