Opis

Komentarz do analizy

Flavonoids are polyphenolic compounds ubiquitous in nature and classified, according to their chemical structure, into flavonols, flavones, flavanones, isoflavones, catechins, anthocyanidins and chalcones. They are widely present in fruits, vegetables, leaves, nuts, seeds, bark and beverages (tea, coffee, beer, wine and fruit drinks).
