摘要：

Examination of eight different polyhydroxyalkylpyrazines by Curie-point pyrolysis-capillary gas chromatography-mass spectrometry resulted in the identification of 44 compounds including 32 pyrazine derivatives. Among these were some pyrazinecarboxaldehydes, which had never before been found in the pyrolyzates of substances formed by reactions of sugars with ammonia. Mass spectrometric fragmentation patterns of these compounds are given.
