Biosynthetically Diverse Compounds from a Saltwater Culture of Sponge-DerivedAspergillus niger

Abstract
The new compound, asperic acid (1), and the known compounds hexylitaconic acid (2), malformin C (3), pyrophen (4), and asperazine (5) were isolated from the saltwater culture of Aspergillusniger derived from a Caribbean sponge, Hyrtiosproteus. The structure elucidation of asperic acid is presented.
