  1. 1. Synthesis and analysis of potential metabolites of ADB-5´Br-BUTINACA

    University essay from Linköpings universitet/Kemi

    Author : Alaa Malekshahineia; [2023]
    Keywords : metabolites; NPS; synthetic cannabinoids;

    Abstract : In recent years, there has been a rise in the use of New Psychoactive Substances (NPS) that mimic the effects of controlled drugs and licensed medicines, which have become a significant public health concern globally. Synthetic cannabinoids, a rapidly expanding category of NPS, with much higher potency and binding affinity to the cannabinoid receptors than ∆9-tetrahydrocannabinol (THC), have led to serious psychiatric complications and other adverse effects.

  3. 2. Analysis of non-volatile chemicals from graminoid plants

    University essay from KTH/Kemi

    Author : Jakob Flygar; [2022]
    Keywords : Liquid Chromatography; Cyperus Rotundus; Panicum Repens; Malaria; Mass spectrometry; Vätskekromatografi; Cyperus Rotundus; Panicum Repens; Malaria; Masspektrometri;

    Abstract : Syftet med denna studie var att utveckla en separations- och analysmetod för identifiering av icke-volatila substanser från strån och rötter av de gräsliknande växterna Cyperus rotundus och Panicum repens. För analysen användes högpresterande vätskekromatografi (HPLC) och ultrahögpresterande vätskekromatografi (UHPLC) med en opolär stationär fas (RP-HPLC) med ultraviolett ljus (UV) och elektrosprej masspektrometri detektion (ESI-MS).
