A new isoflavone from the mangrove endophytic fungus Fusarium sp (ZZF60)

A new isoflavone, 5-hydroxy-7-methoxy-4'-O-(3-methylbut-2-enyl) isoflavone (1), together with five known compounds, eriodictyol (2), vittarin-B (3), 3,6,7-trihydroxy-1-methoxyxanthone (4), 1,3,6-Trihydroxy-8-methylxanthone (5) and cyclo (Phe-Tyr) (6), was isolated from the mangrove endophytic fungus, Fusarium sp. ZZF60 obtained from the South China Sea. Their structures were determined by the analysis of spectroscopic data.
