The mass spectra of indolizidin-8-ol derivatives (1-6) were measured by electron impact ionization.The characteristic fragment ions were observed in the mass spectra of the indolizidin-8-ol derivatives at m/z 154, m/z 140, m/z 136, m/z 110, m/z 97, m/z 96, m/z 84, m/z 70, m/z 69, and m/z 55.The peak intensities at M+· and m/z 154 in the mass spectra at 70 ev of the epimers of indolizidin-8-ol derivatives show little difference, but careful examination of the spectra at 70 eV and 20 eV enables distinction between two epimers. The difference between alkyl and phenyl substituents can be recognized by the peak intensities at m/z 154, m/z 140, and m/z 136.
