Chemical analysis of seven Amanita mushrooms sold in Japan (five Amanita muscaria and two Amanita pantherina) and four products labeled as extracts of A. muscaria found that the mushrooms contained the dissociative compounds ibotenic acid and muscimol at varying levels, with caps having higher concentrations than stems and flesh more than cuticle. In contrast, the extract products contained little to none of these compounds but instead held other psychoactive substances, including tryptamines, monoamine oxidase inhibitors, and tropane alkaloids, indicating adulteration.
