Polüfenole

Polüfenole is a term used to describe a large group of naturally occurring organic compounds characterized by the presence of more than one phenol unit in their molecular structure. Phenols themselves are organic compounds that contain a hydroxyl group (-OH) bonded directly to an aromatic hydrocarbon group. This structural feature gives polyphenols their characteristic chemical properties and is central to their diverse biological activities.

These compounds are widely distributed throughout the plant kingdom, found in fruits, vegetables, cereals, legumes, tea, coffee, wine, and chocolate. The specific type and concentration of polyphenols can vary significantly depending on the plant species, cultivar, growing conditions, and processing methods. Some common examples of polyphenol classes include flavonoids, phenolic acids, stilbenes, and lignans.

Polyphenols are of significant interest due to their potent antioxidant properties. The hydroxyl groups present in their structure can readily donate hydrogen atoms, neutralizing free radicals that can cause cellular damage. Beyond antioxidant activity, research suggests that polyphenols may also possess anti-inflammatory, antimicrobial, and potential anti-cancer effects. Their role in human health is an active area of scientific investigation, with dietary intake of polyphenol-rich foods being associated with a reduced risk of certain chronic diseases.
