Norbaeocystin is a psilocybin mushroom alkaloid and analog of psilocybin. It is found as a minor compound in most psilocybin mushrooms together with psilocin, psilocybin and baeocystin.
Norbaeocystin is a N-demethylated derivative of baeocystin (itself a N-demethylated derivative of psilocybin), and a phosphorylated derivative of 4-hydroxytryptamine.
