A new decalin derivative, trichoharzianol (1), together with three known compounds, eujavanicol A (2), 5-hydroxy-3-hydroxymethyl-2-methyl-7-methoxychromone (3), and 4,6-dihydroxy-5-methylphthalide (4), were isolated from Trichoderma harzianum F031. For the first time, compounds 2-4 were reported from the Trichoderma species. Their structures were characterized by spectroscopic methods. Trichoharzianol (1) showed the highest antifungal activity against Colletotrichum gloeosporioides, with a minimum inhibitory concentration (MIC) of 128 μg/mL.Mahidol UniversityAgricultural and Biological SciencesChemistryArticleSCOPUS10.1021/acs.jafc.5b01258
