ABSTRACT
Objective To search for novel antifungal structures produced by marine fungus.Methods Using the Pyricularia oryzae (P.oryzaae) bioassay method to screen marine fungi led to the isolation of marine fungus 09-1-1-1.Active metabolites were isolated from the broth of the marine fungus 09-1-1-1.Results Two compounds were extracted from the mycelium and their structures were elucidated by various spectroscopic methods as 3a,12c-dihydro-8-hydroxy-6-methoxy-7H-furo\furo\xanthen-7-one(Ⅰ,sterigmatocystin) and 1,3,6,8-tetrahydroxy-2-(1-hydroxyhexyl)anthraquinone(Ⅱ,averantin).Conclusion The P.oryzae bioassay was a cheap,quick and convenient method for the screening of bioactive substances from marine fungi.Compound Ⅱ showed potent inhibitory activity to the mycelia of P.oryzae.The MIC of compound Ⅱagainst P.oryzae was 1.6 ?g?mL~(-1).
