 Muscazone is another compound that has more recently been isolated from European specimens of the fly agaric . It is a product of the breakdown of ibotenic acid by ultra @-@ violet radiation . Muscazone is of minor pharmacological activity compared with the other agents . Amanita muscaria and related species are known as effective bioaccumulators of vanadium ; some species concentrate vanadium to levels of up to 400 times those typically found in plants . Vanadium is present in fruit @-@ bodies as an organometallic compound called amavadine . The biological importance of the accumulation process is unknown .
