Fig. 4 in The grass root endophytic fungus Flavomyces fulophazii: An abundant source of tetramic acid and chlorinated azaphilone derivatives

Fig. 4. Characteristic MS fragmentation of azaphilone compounds 6a, 7–11 (A) and 6b flavochlorine F (B) along with their backbone specific fragment ion structure (C). Corresponding fragment ions generated from protonated molecular ions of these azaphilones by various collision induced dissociation energies, are detailed in the Supplementary Tables S2 and S3.
