Analysis of 28 hair samples from users of the hallucinogenic beverage ayahuasca

Forensic Science International April 20, 2021 Mengxi Liu, Huan Yang, Jing Hu et al. 14 citations

Ayahuasca is a psychoactive beverage widely used in religious ceremonies in Amazonia. Dimethyltryptamine is the main active compound of ayahuasca. Dimethyltryptamine has many hazardous effects, including hallucinations. In the present study, a fast and reliable UPLC-MS/MS method was developed and validated for the quantitation of dimethyltryptamine in hair samples. Twenty-milligram hair samples...

UHPLC-MS/MS method for simultaneously detecting 16 tryptamines and their metabolites in human hair and applications to real forensics cases.

Journal of chromatography. B, Analytical technologies in the biomedical and life sciences November 30, 2020 Yan Shi, Roujia Wang, Shuai Yuan et al.

Tryptamines are hallucinogenic substances many of which have appeared recently as novel psychoactive substances (NPS). Herein, we describe the establishment of a rapid UHPLC-MS/MS quantitative method for the targeted screening of 16 tryptamines of abuse in hair. Twenty milligram pieces of hair were pulverized below 4 °C in 0.5 mL of deionized water containing 0.1% formic acid and an internal...

Development of an LC-MS/MS method for determining 5-MeO-DIPT in dried urine spots and application to forensic cases.

Journal of Forensic and Legal Medicine May 1, 2020 Xiuying Yan, Shuai Yuan, Zhiguo Yu et al.

The dried urine spots (DUSs) technique is increasing continuously as an easy sampling method for monitoring substance abuse due to its advantages of stability and convenience regarding transport and storage. 5-Methoxy-N,N-diisopropyltryptamine (5-MeO-DIPT) is a new type of tryptamine hallucinogen, the use of which has been banned in many countries. And according to the previous research,...

Determination of 5-MeO-DIPT in Human Urine Using Gas Chromatography Coupled with High-Resolution Orbitrap Mass Spectrometry

Journal of Analytical Toxicology January 29, 2020 Xiuying Yan, Ping Xiang, Yunli Zhao et al. 20 citations

5-Methoxy-N,N-Diisopropyltryptamine (5-MeO-DIPT) is a designer hallucinogen derived from tryptamine and its use has been banned by many countries. In this study, a qualitative and quantitative method was developed for determining 5-MeO-DIPT in urine by gas chromatography high-resolution mass spectrometry. 5-hydroxy-N,N-diisopropyltryptamine (5-OH-DIPT) and 5-methoxy-N-isopropyltryptamine...

Application of hair analysis to document illegal 5-methoxy-N,N-dissopropyltrptamine (5-MeO-DiPT) use.

Forensic Science International November 1, 2019 Roujia Wang, Ping Xiang, Zhiguo Yu et al.

5-Methoxy-N,N-diisopropyltryptamine (5-MeO-DiPT) is a designer hallucinogen that is a synthetic tryptamine derivative. It is highly abused and is involved in criminal activities because of its psychotropic properties. Herein, we presented an UHPLC-MS/MS method allowing for the qualitative and quantitative determination of 5-MeO-DiPT in human hair. The hair was first decontaminated and then cut...
