 Title    Substrate Specificity in the Fungal Metabolism of Prenylated Flavonoids  
 Abstract    The prenylated flavonoids, topazolin [5,7,4'-trihydroxy-3-methoxy-6-(3,3-dimethylaIlyl)-flavone], piscerythrone [5,7,2',4'-tetrahydroxy-5'-methoxy-3'-(3,3-dimethylallyl)isoflavone] and piscidone [5,7,4',5'-tetrahydroxy-2'-methoxy-6'-(3,3-dimethylallyl)isoflavone] were meta­ bolized by Aspergillus flavus and Botrytis cinerea to give a variety of products. Topazolin and piscerythrone were converted by both fungi to com pounds similar to those previously ob­ tained from luteone (6-prenyl) and licoisoflavone A (3'-prenyl) respectively. The 6'-prenylated isoflavone piscidone was metabolized only by B. cinerea to give the corresponding dihydro-pyrano-isoflavone as a m ajor product. N either fungus was found to metabolize the 8-prenylated pyranoflavanonol lupinifolinol.
