Development and validation of an analytical method for the determination of select 4-position ring-substituted tryptamines in plasma by liquid chromatography–tandem mass spectrometry

Journal of Analytical Toxicology May 26, 2025 Malik Schoffner, Vamshikrishna Reddy Sammeta, Marilyn Naeem et al. 2 citations

Abstract 4-Phosporyloxy-N, N-dimethyltryptamine (psilocybin) is a psychedelic tryptamine found in certain mushroom species that has shown efficacy in the treatment of various psychiatric disorders. In conjunction with the renewed interest in therapeutic effects of psychedelics, there has been an increase in psilocybin-like designer tryptamines appearing in non-medical drug markets. The present...

Essential oil-based dispersive liquid-liquid microextraction for the determination of N,N-dimethyltryptamine and β-carbolines in human plasma: A novel solvent-free alternative

Talanta December 9, 2020 Gabriela de Oliveira Silveira, Felipe Rebello Lourenço, Ana Miguel Fonseca Pego et al. 15 citations

The present study describes the development of a novel solvent-free vortex-assisted dispersive liquid-liquid microextraction alternative based on a natural essential oil as extracting solvent (VA-EO-DLLME) for the determination of N,N-dimethyltryptamine (DMT), harmine (HRM), harmaline (HRL) and tetrahydroarmine (THH) (compounds found in the ayahuasca tea, a psychedelic plant preparation) in...
