Collisionally activated dissociation (CAD) of [M+H]⁺ of ustiloxins and phomopsins was examined. Fragments of ustiloxins were formed by the cleavage of O(1)-C(2) and the peptide chain to form “a”, “b”, “x”, and “y” series ions, and of the C(9)-C(10) bond to form ions “M-Bz” and “b-Bz”. Phomopsins gave the “b” and “y” series ions. The difference may be at least partly explained by different hydrogen bond-forming characteristics of ustiloxins and phomopsins.
