Flavonoids and Polyphenols
Flavonoids are phenolic compounds that contain a structure of 15 carbon atoms, consisting of two aromatic rings linked by a three-carbon bridge. Polyphenols are a broader class of organic compounds containing multiple phenolic groups. Both groups have potent antioxidant properties, allowing them to protect cells from damage caused by free radicals. Flavonoids are commonly found in fruits, vegetables, and tea and are associated with improved cardiovascular health and the prevention of chronic diseases. Polyphenols also have applications in cancer prevention and brain health promotion.
At CymitQuimica, we offer high-quality flavonoids and polyphenols for research in chemistry, pharmacology, and biomedicine.
