Abstract
The EI, FD and FAB mass spectra of saframycins, isoquinolinequinone antibiotics, have been examined. The FD spectra gave intense molecular ions as the base peak in all cases. The general fragmentation pattern observed in EI and FAB spectra has been discussed. In particular, unique and significant fragment ions for structural study of the antibiotics were found in the FAB spectra.
