Two new naphthoquinone derivatives, 6-hydroxy-astropaquinone B (1) and astropaquinone D (2) as well as the known compound 3-O-methyl-9-O-methylfusarubin (3) were isolated from Fusarium napiforme, an endophytic fungus isolated from the mangrove plant, Rhizophora mucronata. The structures of 1 and 2 were determined by 1D and 2D NMR spectroscopic analyses. Compounds 1, 2 and 3 exhibited moderate antibacterial activity against Staphylococcus aureus and Pseudomonas aeruginosa. Furthermore, 1, 2 and 3 were phytotoxic action in lettuce seeding at a concentration of 30 μg · mL−1.
