Abstract

Two new secoanthraquinone derivatives, wentiquinones A (1) and B (2), together with the eight known compounds 310, 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.
