Benzoylecgonine is the most common metabolite measured in urine drug screens to detect cocaine use. Erythroxin coca one of several species of cocaine plants grown in the Andes mountains. Cocaine is contained in the leaves. N-Acetylcysteine (NAC) an amino acid that is used in clinical medicine ...
Hippenstiel MJ, Gerson B.Optimization of storage conditions for cocaine and benzoylecgonine in urine: a review. J Anal Toxicol. 1994 Mar-Apr;18(2):104-9 Abstract The maximum stability conditions for cocaine and its metabolite benzoylecgonine (BE) in urine were analyzed. Suggestions were presented...
But it still leads me back to the first and most important question that I am posing. How come, if I tested positive for cocaine, both in a urine test and then in a hair strand test are their no metabolites present in either case? I hope someone with actual knowledge by way of educa...
[9–14].Occasionally, radio immuno-in a non-invasive and observable way,which makes assay has also been employed to measure morphine it unique compared to plasma or urine.Furthermore, in saliva [15].GC–MS is also the most popular concentrations in saliva have been suggested to technique ...

Nevertheless, it was not possible to conduct a standard recovery test in ratios higher than 9:1 (v/v) of urine to acid due to a lack of response. In conclusion, this methodology offers a reliable approach for determining BE, an important analyte in forensic chemistry, and the DoE allows ...
To determine the effectiveness of the QRPDA method for quantifying cocaine in biological samples, mice were injected with a sub-locomotor activating dose of cocaine (5 mg/kg; i.p.) and were found to have detectable levels of COC/BE in their urine (160.6 ng/ml) and blood plasma (8.1 ...
Objective To establish a liquid chromatography-tandem mass spectrometry(LC-MS/MS) method for the simultaneous analysis of cocaine(COC) and its metabolite benzoylecgonine(BZE) in urine samples. 目的建立尿液中可卡因(cocaine,COC)及其代谢物苯甲酰爱康宁(benzoylecgonine,BZE)的液相色谱-串联质谱分析方法。
