When incubated in liquid culture with Aspergillus flavus, the prenylated flavanone 6-prenylnaringenin [(2S)-6-(3,3-dimethylallyl)-5,7,4'-trihydroxyflavanone] was converted into 2,3-dihydrodihydroxyprenyl-substituted naringenin, 6-prenylnaringenin hydrate, and dihydrofurano-substituted naringenin, The latter metabolite was also found as the major metabolite of 6-prenylnaringenin in Botrytis cinerea culture. Further experiments using a strain of Ascochyta rabiei pathogenic to chickpea, which can metabolize non-planar isoflavonoid pterocarpans, revealed that 6-prenylnaringenin gave only a minute amount of metabolites, whilst the prenylated isoflavone luteone [6-(3,3-dimethylallyl)-5,7,2',4'-tetrahydroxyisoflavone] was slowly converted into the corresponding dihydrofuranoisoflavone.
