Isolation and identification of antibiotic albaflavenone from Dictyophora indusiata (Vent:Pers.) Fischer

A sesquiterpene antibiotic was isolated from the dried fruiting body of Dictyophora indusiata (Vent:Pers.) Fischer by solvent extraction and column chromatography and identified as albaflavenone by FTIR, GC-MS, HR-FIMS and NMR spectra. The content of albaflavenone in the dried fruiting body of Dictyophora indusiata (Vent: Pers.) Fischer (the content of water was 15.63%) was quantified by GC through an external standard method to be about 0.0063%. The compound isolated has an earthy, camphor-like odour.
