Six new metabolites, including two diphenolic derivatives (1 and 2), one pseurotin (3), one butenolide derivative (4), one benzopyran (5) and one isochromane lactone (6), together with ten known compounds (7-16) were isolated from an endophytic fungus Aspergillus sp. Their planar structures and absolute configurations were established based on techniques of MS, NMR, IR, UV, [Rh2(OCOCF3)4] complex-induced ECD, quantum chemical electronic circular dichroism (ECD) calculations, and single crystal X-ray diffraction. Structurally, compound 2
