Detection of 1-benzylpiperazine, 1-(3-trifluoromethylphenyl)-piperazine, and 1-(3-chlorophenyl)-piperazine in 3,4-methylenedioxymethamphetamine-positive urine samples.
Historically, ecstasy tablets contained 3,4-methylenedioxymethamphetamine (MDMA) as the psychoactive component. In recent years, the Drug Enforcement Administration (DEA) and other law enforcement agencies have seized ecstasy tablets that are comprised of psychoactive drugs or drug mixtures other than MDMA. Many jurisdictions have reported the presence of piperazine derivatives including 1-benz...

There are well over 500 registered pesticides worldwide for use in agricultural regions and new agrochemicals are introduced to the marketplace continuously. This chapter deals with the chemical analysis methods for the main pesticide chemical classes that are most frequently analyzed with gas chromatography (GC) or liquid chromatography (LC) coupled to mass spectrometry (MS). GC amenable pesti...
متن کاملLC-ESI-MS/MS Alkaloidal Profiling and Biological Investigation of Cleistocactus winteri Stems
Cleistocactus winteri is a succulent plant of the Cactaceae family, commonly known as the golden rat tail. Many members of the Cactaceae family are the focus of chemical and biological studies as they contain bioactive compounds, well known for their health-related properties. We aimed to investigate Cleistocactus winteri stems both phytochemically and biologicallyfor the firs...

متن کاملAnalysis of 136 pesticides in avocado using a modified QuEChERS method with LC-MS/MS and GC-MS/MS.
A simple and high-throughput screening method for the analysis of 136 pesticides in avocado ( Persea americana ) by LC-(+)-ESI-MS/MS and GC-MS/MS is presented. A modified QuEChERS sample preparation method was developed to improve the extraction recovery of highly lipophilic pesticides. Extracts from minced avocados after acetonitrile (MeCN) extraction were directly injected to LC-MS/MS, wherea...
