New prenylxanthones, polyketide hemiterpenoid pigments from the endophytic fungus Emericella sp. XL029 and their anti-agricultural pathogenic fungal and antibacterial activities

Abstract

Four new prenylxanthones and five known compounds were isolated from the plant endophytic fungus<italic>Emericella</italic>sp. XL029. Biological assays revealed that the compounds showed selective inhibitory activity against bacterial and fungal strains.
