Abstract
- Eight peptide toxins were isolated and purified from basidiocarps of Amanita exitialis with high performance liquid chromatography and were subjected to ultraviolet, nuclear magnetic resonance and mass spectrometry. We identified seven peptide toxins, α-amanitin, β-amanitin, amaninamide, phallacin, phallacidin, phallisacin and desoxoviroidin. The molecular weight (729.5 Da) of the eighth compound did not match that of any reported Amanita toxins and, although the UV absorption spectrum indicated it to be a phallotoxin, further studies are required to identify this component. This is the first report of amaninamide, phallacin, phallisacin and desoxoviroidin in this lethal mushroom species. [ABSTRACT FROM AUTHOR]
