Here, we investigated the use of on-line sample extraction coupled to rapid chromatography systems for tandem mass analysis of COC, EMF, and BZE in human urine. Using this method, sample preparation consisted of a sole In this study, 25 postmortem urine specimens testing positive, for cocaine and ecogonine methyl ester (EME) by full scan electron impact gas chromatography/mass spectrometry, were used to evaluate the stability of EME in refrigerated and frozen conditions. After an initial quantitation (t = 0), these specimens were split and stored at either 4 degrees C or -20 degrees C. At several intervals Recently, ecgonine methyl ester (methylecgonine) has been shown to be major urinary metabolite of cocaine in man after oral administration. These results indicate that ecgonine methyl ester is a prominent urinary metabolite after street use of cocaine, which primarily involves intranasal application and intravenous injection rather than ingestion.

1 Jun 1997 Ecgonine Methyl Ester, a Major Cocaine Metabolite, Causes Cerebral EME and BE have been detected in urine and/or plasma after cocaine Ecgonine methyl ester is a major urinary metabolite of cocaine, a popular illicit drug applications in urine drug testing, clinical toxicology or forensic analysis. Benzoylecgonine (BZE) is the mayor metabolite of cocaine in urine and its presence (NorCE), ecgonine (EC) and anhydroecgonine methyl ester (AEME) were A study on the stability of anhydroecgonine methyl ester (crack biomarker), benzoylecgonine, and cocaine in human urine.
