A method has been developed for the rapid isolation and identification of psilocin from psilocin/psilocybin-containing mushrooms. Based on the difference in the solubility properties in butyl chloride of psilocin and other constituents present in psilocin/psilocybin-containing mushrooms, psilocin was easily separated in pure form.
