Psilocybin and psilocin levels in twenty species from seven genera of wild mushrooms in the Pacific Northwest, U.S.A.

Journal of Ethnopharmacology May 1, 1982 Michael Beug, Jeremy Bigwood 63 citations

An analysis of twenty mushroom species from seven genera in the Pacific Northwest detected psilocybin—and sometimes psilocin—in seven species across three genera. The amount of these compounds varied more than sevenfold between different collections of the same species. In mushrooms used recreationally or entheogenically, total psilocybin and psilocin levels ranged from 0.1% to nearly 2% of dry weight.

Quantitative analysis of psilocybin and psilocin and psilocybe baecystis (singer and smith) by high-performance liquid chromatography and by thin-layer chromatography

Journal of Chromatography A March 1, 1981 Michael Beug, Jeremy Bigwood 52 citations

A method for rapidly measuring the amounts of psilocybin and psilocin in wild mushroom extracts uses reversed-phase high-performance liquid chromatography with paired-ion reagents. Nine solvent systems and three solid supports were tested for how well they separate psilocybin, psilocin, and other components of crude mushroom extracts using thin-layer chromatography.

Variation of psilocybin and psilocin levels with repeated flushes (harvests) of mature sporocarps of Psilocybe cubensis (earle) singer

Journal of Ethnopharmacology May 1, 1982 Jeremy Bigwood, Michael W. Beug 42 citations

In controlled cultures of Psilocybe cubensis mushrooms, psilocin levels were generally zero in the first or second fruiting flush and reached a maximum by the fourth flush. Psilocybin levels were nearly always at least twice those of psilocin, showed no consistent trend across flushes, but varied up to fourfold. Mushroom samples from outside sources had psilocybin levels varying more than tenfold between collections.
