Determination of the naturally occurring vanadium-complex amavadin in Amanita muscaria with HPLC-ICPMS

Abstract

Amanita muscaria, also known as the fly agaric mushroom, can accumulate vanadium (V), with up to several hundred mg V kg-1 dry mass. It is long known that V is...

Reasons, Form of Ingestion and Side Effects Associated with Consumption of Amanita muscaria

“…It should also be noted that individual symptoms may be due to the presence of a number of other toxic elements. An example is the accumulation of speciation forms of vanadium, for which poisoning manifests itself, among other things, as irritation of the gastrointestinal tract [25,26]. Research to date has been based on investigating the toxic element content of Amanita muscaria in different parts of this fungus.…”

Atomic Spectrometry Update: review of advances in elemental speciation

“…All three of the reports of V speciation describe chromatographic separation with ICP-MS detection. Anion-exchange HPLC was applied to speciation in Amanita muscaria (fly agaric mushroom) 174 and in estuarine waters. 175 A. muscaria is unusual in being able to accumulate concentrations of V up to 100 mg kg −1 dw, most of which is present as a compound known as amavadin, whose biological function is not known.…”

Amanita muscaria: Ecology, Chemistry, Myths

“…To be a good quality bioindicator, an organism has to be able to accumulate a compound. A. muscaria effectively accumulates Hg and labile forms of Cd, K, Rb, and V-up to 0.1% of the dry mass in the lower part of the stipe, the latter being stabilized with ligands in the mushroom as amavadin complex [12,25,26]. A good bioindicator also has to be robust to the effect of the maturation stage on the composition of the monitored compound.…”
