5,7-Dihydroxyflavonoids have antifungal activities against P. italicum. C-4′-OH and C-3-OH are crucial for antifungal activities of 5,7-dihydroxyflavonoids. Glycosylation could affect the antifungal activity of 5,7-dihydroxyflavonoids. The relationship between antifungal activity and respiration inhibition have been discussed.
