The content of tryptamine derivatives in Psilocybe semilanceata, a popular hallucinogenic mushroom, was measured by high-performance liquid chromatography. Most of the 52 samples have been collected at several localities in Switzerland during a 1-5 year period. The content of psilocybin and baeocystin varied in the range of 0.21-2.02% and 0.05-0.77%, respectively, whereas only traces of...
Abstract Baeocystin ( 7 ) (4‐phosphoryloxy‐N‐methyltryptamine) has been synthesized starting from 2‐methyl‐3‐nitrophenol ( 1 ). The spectral data (UV, IR, 1 H‐, 31 P‐, 13 C‐NMR, MS) are identical with those of 7 isolated from Psilocybe semilanceata .
