A sensitive immunochemical method for identifying hallucinogenic mushrooms (magic mushrooms) is required for regulating their illicit use. We have previously generated a monoclonal antibody (mAb) that targets psilocin (Psi), the major psychoactive compound in hallucinogenic mushrooms, and developed an enzyme-linked immunosorbent assay (ELISA). However, this ...
Hallucinogenic mushrooms (e.g. Psilocybe and Panaeolus species) as well as leaves and young shoots of the khat tree (Catha edulis Forsk) are illicit drugs in many countries. The exact concentration of the hallucinogenic alkaloids psilocin and psilocybin in mushrooms and the sympathomimetic alkaloids cathinone and cathine in khat is usually essential for juri...
Indole alkaloids of Psilocybe cubensis have been reported to be the potential candidates for drug discovery in central nervous system (CNS) disorders. In this research, the effect of the harvesting light on increasing the active alkaloids of P. cubensis was investigated. Three different lighting conditions, that is, dim daylight, indirect daylight, and darkn...
Psilocin was identified in a urine specimen collected during a routine driving under the influence of drugs investigation, the first for this laboratory. The subject did not exhibit any response to an automobile crash, indicating the he may have been unaware of the severity of the situation or his immediate surroundings. The urine specimen gave a positive re...
Accurate and sensitive analytical methods for psilocin (PC) and psilocybin (PB), tryptamine-type hallucinogens contained in "magic mushrooms," were investigated using liquid chromatography-mass spectrometry (LC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS-MS). The chromatographic separation on an ODS column and mass spectral information gave...

Psilocin and psilocybin are psychoactive components of mushrooms of the genus Psilocybe and many others (Panaeolus, Inocybe, Pluteus etc.). In our republic, several species of Psilocybe with a high content of these components can be found. In the present study, we give a semiquantitative content of psilocin and psilocybin in some of our mushrooms in dry subs...
Pharmacokinetic studies of psilocybin in humans have shown the rapid dephosphorylation of psilocybin to psilocin with further conversion to 4-hydroxy-tryptophole (4HT) and 4-hydroxyindole-3-acetic acid (4HIAA) in plasma. Our study shows that psilocin also undergoes conjugation and can be found in the urine as the psilocin-glucuronide conjugate. Recoveries af...

In this study a fatal case caused by the ingestion of magic mushrooms is reported. After a trip to the Netherlands a young girl had ingested a handful of psilocybe mushrooms with a soft drink. Soon later, she was trying to fly from the window and died in the street while falling from a room situated on the second floor of a house. The victim was not known by...
A review of techniques used to screen biological specimens for the presence of drugs was conducted with particular reference to systematic toxicological analysis. Extraction systems of both the liquid-liquid and solid-phase type show little apparent difference in their relative ability to extract a range of drugs according to their physio-chemical properties...
A new method has been developed for the rapid analysis of psilocybin and/or psilocin in fungus material using ion mobility spectrometry. Quantitative analysis was performed by gas chromatography-mass spectrometry after a simple one-step extraction involving homogenization of the dried fruit bodies of fungi in chloroform and derivatization with MSTFA. The pro...
Capillary electrophoresis was utilized for the rapid determination of psilocybin in the hallucinogenic mushroom Psilocybe semilanceata. Following a simple two step extraction with 3.0 + 2.0 ml methanol, the hallucinogenic compound was effectively separated from matrix components utilizing capillary zone electrophoresis (CZE) with a 10 mM borate/phosphate run...
While the hallucinogenic mushrooms Psilocybe semilanceata have previously been analyzed for the indole alkaloids psilocybin and baeocystin by capillary zone electrophoresis (CZE) at pH 11.5, the present work focused on the development of an alternative and complementary capillary electrophoretic method for their identification. Owing to their structural simi...
