摘要

Abstract The yellow zoochrome of the sponge Verongia aerophoba, which blackens when exposed to the air, has been isolated and its structure established as 3, 5, 8-trihydroxy-4- quinolone. The pigment is easily oxidized to an unstable blue quinone which quickly gives rise to an unsoluble black material.
