Two New Secoanthraquinone Derivatives from the Marine-Derived Endophytic Fungus Aspergillus wentii EN-48.

Two new secoanthraquinone derivatives, wentiquinones A ( 1) and B ( 2), together with the eight known compounds 3- 10, were isolated from the culture extracts of Aspergillus wentii EN-48, an endophytic fungus derived from an unidentified marine brown algal species of the genus Sargassum. The structures of these compounds were elucidated on the basis of extensive spectroscopic analysis. [ABSTRACT FROM AUTHOR]
