Two new chromones, phomochromone A and B (1 and 2), and one new natural cyclopentenone, phomotenone (3), have been isolated from the endophytic fungusPhomopsis sp. through a bioassay-guidedprocedure. The absolute configurations of compounds 1–3 were assigned by TD-DFT CD calculations. Compounds 1–3 showed good antifungal, antibacterial, and antialgal activities.
