Baeocystin in Psilocybe semilanceata

Area of Science:

• Mycology
• Pharmacology
• Natural Product Chemistry

Background:

• Psilocybe mushrooms are known for containing psychoactive compounds.
• Baeocystin and psilocybin are key tryptamines found in various species.
• Understanding the distribution of these compounds is important for taxonomy and pharmacology.

Purpose of the Study:

• To identify and quantify specific psychoactive compounds in Psilocybe semilanceata.
• To investigate the presence of these compounds in a related species, Psilocybe pelliculosa.
• To confirm the chemical structures of isolated compounds.

Main Methods:

• Extraction of compounds from mushroom samples.
• Analysis using mass spectrometry (MS) for structural identification.
• UV spectroscopy for corroboration of compound structures.

Main Results:

• Baeocystin and psilocybin were identified in extracts of Psilocybe semilanceata.
• Psilocybin was detected in Psilocybe pelliculosa, but baeocystin was not.
• Trace amounts of psilocin were found in both studied species.

Conclusions:

• The study confirms the presence of baeocystin and psilocybin in Psilocybe semilanceata.
• It provides evidence for the presence of psilocybin in Psilocybe pelliculosa, differentiating it from Psilocybe semilanceata.
• The findings contribute to the chemical understanding of these two closely related species.
