Etymology

The term 'polyphenol' originates from the Greek words 'poly' meaning many and 'phenol,' which refers to a type of organic compound that consists of a hydroxyl group (-OH) attached to an aromatic hydrocarbon group. Polyphenols are characterized by their multiple phenolic hydroxyl groups, which contribute to their chemical structure and biological activity. They were first identified in the mid-19th century when chemists began studying the chemical compounds found in plant materials. The recognition of their health benefits has grown significantly since the 1980s, particularly due to research highlighting their antioxidant properties and potential role in reducing the risk of chronic diseases such as heart disease, diabetes, and cancer. Today, polyphenols are widely studied in nutritional science, pharmacology, and biochemistry for their various health-promoting effects.
