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...
Thin-layer chromatography confirmed the presence of psilocybin in Psilocybe semilanceata and P. coprinifacies collected in Czechoslovakia. In P. semilanceata , this is the first proof of psilocybin in native fruit bodies. For P. coprinifacies , it is a new finding. The concentration of psychotropic compounds was species-specific and stable. Psilocin was not definitively detected.
