Aspergillus sp. F184 was isolated from soil for the development of new xanthine oxidase inhibitor. This xanthine oxidase inhibitor was sequentially purified by filtration, HP-20 adsorption column chromatography, ethyl acetate extraction, silica gel column chromatography and crystallization, and was named as YUX 104. YUX 104 was identified to be 5,6-epoxy-2-hydroxy-3-methyl-2-cyclohexene-1,4-dione(terreic acid) by NMR and mass spectroscopic sudies.
