Two new solanapyrone analogues, solanapyrones N and O (1 and 2, resp.), and three known compounds, solanapyrone C (3), nigrosporalactone (4), and phomalactone (5), were isolated from the fermentation culture of Nigrospora sp. YB‐141, an endophytic fungus isolated from Azadirachta indica A. Juss. The structures of the new compounds were elucidated on the basis of spectroscopic analysis. The antifungal activities of 1–5 towards seven phytopathogenic fungi were tested. Most of the compounds exhibited no or only weak antifungal activities.
