Název v původním jazyce

Isolation and identification of the Amanita muscaria and Amanita pantherina toxins in human urine.

Popis výsledku v původním jazyce

OBJECTIVES: Ibotenic acid, muscimol and muscarine were recognized as responsible for psychotropic effects of A. muscaria and A. pantherina. Demand for their specific and sensitive identification and quantitation in biological material lead to effort to develop reliable analytical method, but satisfactory solution is still lacking. Presented article describes liquid chromatography-mass spectrometry method suitable for isolation and identification of principal toxins of A. muscaria and A. pantherina in urine. METHODS AND RESULTS: Dedicated liquid chromatography-mass spectrometry method is reported. Technique consists of an extraction of analytes on Strata X-CW and Discovery SCX SPE cartridges and separation is achieved using a Gemini C18 column (150 mm x2.0 mm, 5 micron) and 8 mM heptafluorobutyric acid as mobile phase. Detection at m/z 159 for ibotenic acid, m/z 115 for muscimol and m/z 174 for muscarine was used. Retention times and LODs are 2.6 min and 50 ng.ml-1 for ibotenic acid, 4
