Abstract
The vanadium content of different mushrooms of the genus Amanita was measured by atomic absorption spectroscopy. Amanita regalis and Amanita velatipes showed high levels of vanadium comparable with the level present in the fly agaric Amanita muscaria. Electron paramagnetic resonance and high pressure liquid chromatography showed that in these three species amavadin, a vanadium(IV)complex with two N-hydroxy-2,2′-imino dipropionate ligands, was present. In the other species examined, only low levels of vanadium were found.
