(A) Molecular structure of myricetin, dihydromyricetin, and myricitrin. (B) IC50 determination of flavonoids for dihydropyrimidinase using dihydrouracil as a substrate. (C) IC50 determination of flavonoids for dihydropyrimidinase using 5-propyl-hydantoin as a substrate. IC50 value for dihydropyrimidinase was directly determined using graphic analysis.
