The latter route is particularly important since it is globally a route of detoxification that accounts for as much as 90% of the dose in humans, who excrete high urinary concentrations of benzoylecgonine (2), ecgonine methyl ester (3), and ecgonine (4).

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.

Ecgonine methyl ester in urine

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.

The two major urinary metabolites of cocaine are benzoylecgonine (BE) and ecgonine methyl ester (EME). The major advantage of BE screening is that many commercial immunoassays are designed to detect BE. On the other hand, EME is more amenable to gas …

Version 2.69 50592-5Ecgonine methyl ester [Mass/volume] in Urine by Confirmatory methodActive Part Description LP28530-1 Ecgonine methyl ester Ecgonine methyl ester (EME) is a major metabolite of cocaine, a wide spread illicit drug of abuse. [PMID: 7876811] Source: Regenstrief LOINC, PMID: 7876811 Fully-Specified Name Component Ecgonine methyl ester Property MCnc Time Pt System Urine Scale Qn Urine or plasma or serum is spiked with deuterated internal standards cocaine-d3, benzoylecgonine-d3, ecgonine methyl ester-d3, and cocaethylene-d3 and buffered with phosphate buffer. The drugs in the sample are extracted by cation-exchange solid phase extraction.

Spontaneous chemical hydrolysis to benzoylecgonine also occurs and cocaine is therefore unstable in aqueous solution (and urine) at pH values above neutrality. A rapid, rugged, and highly specific assay for the quantitation of cocaine (COC) and especially its primary metabolites benzoylecgonine (BZE) and ecgonine methyl ester (EME) in human urine has 1988-01-01 This work describes a fast and fully validated procedure for the simultaneous detection and quantification of ecgonine, ecgonine‐methyl‐ester, benzoylecgonine, nor‐benzoylecgonine, m‐hydroxybenzoylecgonine, cocaethylene, cocaine, norcocaine and norcocaethylene in human urine (500 μL) using one SPE and simple derivatization. A catalytic antibody against cocaine attenuates cocaine's cardiovascular effects in mice: a dose and time course analysis. Analysis of cocaine, benzoylecgonine, ecogonine methyl ester, and ecgonine by high-pressure liquid chromatography-API mass spectrometry and application to a short-term degradation study of cocaine in plasma. Ecgonine methyl ester: Description: Ecgonine methyl ester, also known as methyl ecgonine, belongs to the class of organic compounds known as tropane alkaloids. These are organic compounds containing the nitrogenous bicyclic alkaloid parent N-Methyl-8-azabicyclo[3.2.1]octane.
