A nove] indophenol-reducing and DPPH radicalscavellging compeumd (1) was iselated from a fungal metabolite. The structure ef 1 was determined by a spectroscopic analysis, and the absolllte configuration of 1 was determined by the modMed Mosher's method. Compound 1 showed slow・reacting DPPH radicalscayenging activity (EDse value of 298 "M sfter 96 hr).
