title: New cyclopentenones from strain Trichoderma sp. YLF-3.
abstract: Two new cyclopentenones, trichodermone A (1) and trichodermone B (2), together with a known compound, 3-(3-oxocyclopent-1-enyl) propanoic acid (3), were isolated from the strain Trichoderma sp. YLF-3. Their structures were elucidated on the basis of their spectroscopic data. All compounds were assayed for antibacterial activity. Compound 3 showed activity against Staphyloccocus aureus and Bacillus cereus.
