Two new nonenolides named diaportheolides A ( 1 ) and B ( 2 ) were isolated from the endophytic fungus Diaporthe sp. SXZ‐19 of Camptotheca acuminata . The chemical structures of 1 and 2 were elucidated by spectroscopic analyses, including 1D‐ and 2D‐NMR experiments and HR‐ESI‐MS data analysis. Their in vitro antibacterial activities are established to be insignificant.
