“…Several techniques have been employed to determine psilocin and psilocybin in hallucinogenic mushrooms for forensic analysis, with high-performance liquid chromatography (HPLC) being by far the most widely used analytical technique. Detection modes include ultraviolet (UV) (1,2,(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18), fluorescence (2,12,13,17,19,20), electrochemical (12), voltametric detection, (6,9), and mass spectrometry (2,5,13,18,20). Other techniques for the determination of psilocin and psilocybin in mushroom samples also include gas chromatography-mass spectrometry (21)(22)(23), capillary electrophoresis (3), infrared spectroscopy (8,23), thin layer chromatography (2,15,18,21,24), gas chromatography (6,25), ion mobility spectrometry (22), and flow injection analysis (26).…”
