Résumé
Microbial transformation of (±)-6-(1,1-dimethylallyl)naringenin (6-DMAN, 1) and (±)-5-(O-prenyl) naringenin-4′,7-diacetate (5-O-PN, 2) was performed by using fungi. Scale-up fermentation studies with Mucor hiemalis, Cunninghamella elegans var. elegans, and Penicillium chrysogenum led to the isolation of five microbial metabolites. Chemical structures of the metabolites were determined by spectral analyses as (±)-8-prenylnaringenin (3), (2S)-5,4′-dihydroxy-7,8-[(R)-2-(1-hydroxy-1-methylethyl)-2,3-dihydrofurano]flavanone (4), (±)-5-(O-prenyl)naringenin-4′-acetate (5), (±)-naringenin-4′-acetate (6), and (±)-naringenin (7), of which 5 was identified as a new compound.
