Albaflavenone. (A) LC-MS analysis of culture broth extract of S. coelicolor's spores after 6 h germination in AM medium with glycerol. MS chromatogram recorded for m/z 219.175. (B) Mass spectrum of compound with tR = 9.01 min. Acquired m/z 219.1741 corresponds to [M+H]+ of albaflavenone with theoretical m/z 219.1749. (C) LC-MS analysis of hexane extract from supernatant of S. coelicolor after 48 h of culture in R3 medium with glycerol (further referred to as albaflavenone-hexane extract). MS chromatogram recorded for m/z 219.175. (D) Mass spectrum of compound with tR = 9.00 min. Acquired m/z 219.1736 corresponds to [M+H]+ of albaflavenone ion with the theoretical m/z 219.1749.
