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.
