In seeds, flavonoids are concentrated in the seed coat, which serves to protect the embryo and nutrient reserves until germination is induced. Most of the alkaloids and flavonoids are present in the flowers and in the ripe fruits. Inhibitory action of some flavonoids on enhanced spontaneous lipid peroxidation following glutathione depletion. The levels of flavonoids did not vary significantly in conventional treatments over the same years. The extraction and separation of the flavonoid compounds were carried out using the following methods. The administered doses of alkaloid and flavonoid fractions correspond to the proportion of these components in the crude extract used in the experiment. The flavonoid baicalein inhibits fibrillation of alpha-synuclein and disaggregates existing fibrils. The total flavonoid content was calculated using = 29 200. For example, carotenoids and flavonoids are acquired in humans through ingestion. The effect was less pronounced in caput, especially for the male rats treated with flavonoid fraction. The crude extract was obtained from plants collected at the beginning of the vegetative cycle, when they contained 0.095 g alkaloids and 1.50 g flavonoids per 100 g dry plant. More work must be done, particularly in relation to flavonoid synthesis. From the Hansard archive Example from the Hansard archive.

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