Fig. 3 in The grass root endophytic fungus Flavomyces fulophazii: An abundant source of tetramic acid and chlorinated azaphilone derivatives

Fig. 3. Extracted ion chromatograms (A–F) for m/z 340.1 (A), m/z 296.1 (B), m/z 252.1 (C), m/z 310.1 (D), m/z 352.1 (E), and m/z 253.1 (F) corresponding to azaphilones, and HR-MS spectra (A′–F′) of azaphilones 6a (flavochlorine E), 7 (flavochlorine A), 8 (flavochlorine B), 9 (flavochlorine C), 10 (flavochlorine G) and 11 (flavochlorine D), respectively, along with their chemical structures (note: HR-MS spectrum of 6b (flavochlorine F) comparable with that of compound 6a, was not depicted). Chromatograms and spectra were obtained from a HPLC separation of the extract prepared from Flavomyces fulophazii culture sample HF-3A.
