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.

Alpha-methyltryptamine (AMT), a psychoactive tryptamine analogue, is metabolized in rats into at least four distinct compounds. After oral administration of 10 mg/kg to male Wistar rats, urine collected over 24 hours was enzymatically hydrolyzed, extracted, and analyzed by gas chromatography/mass spectrometry. The detected metabolites were 2-oxo-AMT, 6-hydroxy-AMT, 7-hydroxy-AMT, and 1'-hydroxy-AMT. These findings identify specific metabolic pathways for AMT, which may inform understanding of its pharmacological effects and duration of action.

After oral administration to rats, the drug 2C-I is broken down into several metabolites through O-demethylation, N-acetylation, and deamination followed by oxidation to carboxylic acid. Five of these metabolites were synthesized in the lab and identified using gas chromatography/mass spectrometry. The findings will aid forensic analysis of 2C-I and its metabolites in biological samples.
