Summary

1. The mass spectra of six alkaloids of the lycorine type (caranine, pluviine, lycorine, methylpseudolycorine, ungminorine, and galanthine) and four derivatives of these alkaloids have been studied.

2. Three main directions of fragmentation of the molecular ions of the compounds studied have been established: the formation of the ion (M-1), the cleavage of ring B in the form of a retrodiene reaction, and the successive elimination of the substituents from rings B and C in the ion (M-1)+.
