Introduction. The ways of phenols classification, which were collected from literature based on structural and biochemical characteristics with description of source Plants need phenolic compounds for pigmentation, growth, reproduction, resistance to pathogens and for many other functions. The most common classification embraces the subdivision of phenolic compounds into two main groups: flavonoid (e.g., anthocyanins, flavanols, flavanones, flavonols, flavonones and isoflavones) and non-flavonoid (e.g., phenolic acids, xanthones, stilbens, lignans and tannins) polyphenols [ 54, 55 ].
