摘要：

Cytosporones O, P and Q, together with the known compounds cytosporones B, C, D, E and dothiorelones A, 13, C. and H were isolated from the ascomycete fungus Cytospora sp. during a chemotaxonomic study Of fungal endophytes belonging to the related genera Cytospora and Phomopsis from Brazil. The structures were determined by NMR spectroscopy and mass spectrometry. With exception of cytosporones D, E, Q and dothiorelone B, all compounds were consistently detected in the metabolite profiles of eight Cytospora isolates investigated; and were also produced by a distinct chemotype of Phomopsis.
