Sixty years ago, the ethnomycologist R. G. Wasson discovered an ancient mushroom cult in Oaxaca, Mexico. 1, 2 The famous mycologist R. Heim classified the psychoactive mushroom species in the genera Psilocybe and the eminent natural product chemist Albert Hofmann published the isolation, structural elucidation and synthesis of the new alkaloids psilocybin and psilocin in 1958. These indole...
Mushroom-forming fungi produce a wide array of toxic alkaloids. However, evolutionary analyses aimed at exploring the evolution of muscarine, a toxin that stimulates the parasympathetic nervous system, and psilocybin, a hallucinogen, have never been performed. The known taxonomic distribution of muscarine within the Inocybaceae is limited, based only on assays of species from temperate regions...
The psychoactive properties of N,N-dimethyltryptamine (DMT) 1a are known to induce altered states of consciousness in humans. This particular attribute attracts great interest from a variety of scientific and also clandestine communities. Our recent research has confirmed that DMT reacts with dichloromethane (DCM), either as a result of work-up or storage to give a quaternary N-chloromethyl...
The hallucinogenic mushroom Inocybe aeruginascens contains several typical Psilocybe alkaloids including psilocybin. We have now elucidated the structure of a further indole derivative named aeruginascin as the quaternary ammonium compound N, N, N-trimethyl-4-phosphoryloxytryptamine. Aeruginascin is closely related to the frog skin toxin bufotenidine (5-HTQ), a potent 5-HT3 receptor agonist,...
Abstract The occurrence and extraction of indole derivatives in six species from four genera of higher fungi were investigated. By using pure methanol for extraction of the mushrooms analysis revealed the highest concentrations of psilocybin and baeocystin. The psilocin content of the species was higher by using aqueous solutions of alcohols than with methanol alone but was an artificial...
Mycelial cultures of PSILOCYBE CUBENSIS, with the ability to form psilocybin and psilocin DE-NOVO, also hydroxylated and methylated fed tryptamine to give psilocin in up to 3.3% dry mass of the obtained fruit bodies. By using HPLC and TLC, it was found that these mushrooms contain only a small amount of psilocybin (0.01-0.2% dry mass). The values of psilocin are the highest described in any...
Abstract Mycelial cultures of Psilocybe cubensis capable of forming psilocybin and psilocin de novo display a high capacity for hydroxylation of tryptamine derivatives at the 4‐position. A specific biotransformation of added synthetic N,N‐diethyl‐tryptamine was found. Thus high amounts of 4‐hydroxy‐N,N‐diethyltryptamine (up to 3.3%) and a minor quantity of 4‐phosphoryloxy‐N,N‐diethyltryptamine...
Psilocybin was quantitatively determined in methanolic extracts of dried fruiting-bodies of the basidiomycete Inocybe aeruginas-cens and its content was compared with that in Psilocybe bohemica and P. semilanceata. By menas of HPLC it was found that the content of psilocybin in Inocybe aeruginascens is lower than in Psilocybe species. Similarly to Psilocybe, the content of psilocybin in Inocybe...
