DE   taxifolin 8-monooxygenase.
CA   (1) (2R,3R)-dihydroquercetin + H(+) + NADH + O2 = (2R,3R)-2,3-
CA   dihydrogossypetin + H2O + NAD(+).
CA   (2) (2R,3R)-dihydroquercetin + H(+) + NADPH + O2 = (2R,3R)-2,3-
CA   dihydrogossypetin + H2O + NADP(+).
CC   -!- Converts a flavanol into a flavanone.
CC   -!- Also acts on fustin, but not on catechin, quercetin or
