Notes:
The negative ion mass spectra of some brassinosteroids are discussed in comparison with their positive ones. In contrast to the EI-mass spectra the negative ion mass spectra show strong peaks in the molecular ion region. The nature of an intense [M - 4]-· ion was investigated on the base of model compounds and deuterium labeled derivatives.
