Notes:
The mass spectrometric characterization of psoralen, isopseudopsoralen, pseudoisopsoralen and angelicin, four variously annulated furanocoumarins of biological interest, has been obtained by different collisional experiments (collision-activated dissociation, charge stripping and charge inversion spectra) performed on molecular species obtained by different ionization methods (electron impact, charge exchange, positive and negative ion chemical ionization). The results so obtained lead to an unequivocal structural identification of these isomeric compounds.
