A new azaphilone derivative, falconensin H (6), was isolated from mycelia of Emericella falconensis, together with previously reported falconensins A- D (1-4) and 3,3'-dihydroxy-5,5'-dimethyldiphenyl ether (5). The structure of 6 was elucidated by spectroscopic investigation and chemical correlations. Among the compounds isolated, only 5 showed antibacterial activity.
