Detection of psilocybin and psilocin in norwegian species of pluteus and conocybe.

A screening of Norwegian mushrooms for the presence of hallucinogenic indole alkaloids was carried out using HPLC with ultraviolet, fluorescence and electrochemical detection. The analysis revealed psilocybin and psilocin in two mushroom species: PLUTEUS SALICINUS and CONOCYBE CYANOPUS. The content of psilocybin and psilocin in dried material of PLUTEUS SALICINUS was determined to be 0.35% and 0.011%, respectively, and dried samples of CONOCYBE CYANOPUS were found to contain 0.33-0.55% psilocybin and 0.004-0.007% psilocin.
