Abstract
A new cyclopentenone derivative, atrovinol (1), together with ten known compounds (2-11) were isolated from Trichoderma atroviride HH-01, an endophytic fungus from Illigera rhodantha (Hernandiaceae). Their structures were identified by HRESIMS, 1 D/2D NMR, and electronic circular dichroism (ECD) spectra. Compound 1 exhibited moderate inhibitory activity against Staphylococcus aureus and Bacillus subtilis with MIC values of 8.0 µg/mL and 16.0 µg/mL, respectively.
