The title compound, C8H10O4, was isolated from culture extracts of the endophytic fungus Xylaria sp. (PB-30). The cyclohexenone ring exhibits a flattened boat conformation. In the crystal structure, molecules related by translation along the b axis are linked into chains through O—H...O hydrogen bonds. Weak non-classical C—H...O contacts are also observed in the structure.
