Examplesofflavonoidflavonoid There was a significant positive relationship between monthly rainfall, monthly minimum temperatures andflavonoidconcentration, but no relationship was found with leaf age. From theCambridge English Corpus In seeds, flavonoids are concentrated in the seed coat, which serves to protect the embryo and nutrient reserves until germination is induced. From theCambridge English Corpus Most of the alkaloids and flavonoids are present in the flowers and in the ripe fruits.

From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under theOpen Parliament Licence v3.0 On exposure to high levels of ultra violet, many plants produce large amounts offlavonoidpigments, which absorb ultra violet and thus minimise damage elsewhere in the cell.
