Three new bianthraquinone metabolites (1-3), along with twelve known compounds (4-15), were isolated from the rice fermentation of the fungus Stemphylium lycopersici (strain number FJJ006) obtained from the sponge collected from Jeju island, Korea. Their structures were elucidated using comprehensive spectroscopic methods. Structures of these new compounds were determined on the basis of NMR and HR-MS analyses, as well as comparison with literatures.Introduction 1 Experimental Section 2 1.
