| Abstract | dc.description.abstract | The electron impact-induced fragmentation of aristolochic acids and
some synthetic model compounds has been investigated using high resolution mass
spectrometry. It was found that the only primary cleavage given by condensed
aromatic systems having a carboxy and a nitro function in peri positions consists of
the elimination of NOr. The complexity which is usually observed in the upper mass
range of the spectra of aristolochic acids is attributable to contaminations with
closely related compounds. The potential of high resolution mass spectrometry for the
analysis of mixtures of aristolochic acids from natural sources is demonstrated. | es_CL |
