Conclusions
The mass spectra of dihydrolycorine, diacetylidhydrolycorine, dihydroungminorine, diacetyldihydroungminorine, and diacetyldihydroungminorinone have been studied.
The fragmentation of these compounds differs from that of alkaloids of the lycorine type only by the absence of a retrodiene type of decomposition.
