Methods Compounds were isolated from the EtOAc extract by chromatography technology and their structures were elucidated on the basis of comprehensive spectroscopic analysis. Results A total of 15 compounds were isolated and their structures were identified as methyl 4-acetamido-3-hydroxybenzoate (1), (E)-methyl5-hydroxy-3-methylpent-2-eno (2), isobenzofuranone A (3), 4-hydroxyacetophenone (4), 6-hydroxy-isosclerone (5), talarojlavone (6), 7-hydroxy-2-hydroxymethyl-5-methyl-4H-chromen-4-one (7), alternarienonic acid (8), 7-hydroxy-2,5-dimethyl-4H-1-benzopyran-4-one (9), 5-hydroxy-epialtenuene (10), alternariol (11), methyl 3-hydroxybenzoate (12), stemphyperylenol (13), altenusin (14), and altenuene (15).
