Chromones from an ascomycete,Chaetomium aureus

A novel chromone, named chaetoaurin (1), along with six known chromone derivatives (2-7), was isolated from the ethyl acetate extract of a solid-state fermented culture of Chaetomium aureus. Their structures were elucidated by extensive spectral analysis. All of these compounds were reported from C. aureus for the first time.
