Flavonoids.

The bright colors of most fruits and vegetables

 

Flavonoids and polyphenols

  • Flavonoids are the class of polyphenols more abundant and widespread in the plant world.
  • They are in different parts of the vascular plants.
  • In 1937 the Hungarian scientist Albert Szent-Györgyi, Nobel Prize in Physiology and Medicine, found its vascular protective properties and gave them the name vitamin P.
  • Until now, it has been found in these natural products, antioxidants, anti-inflammatory, antiplatelet, antihemorrhagic, vasodilator, antineoplastic, antiviral, antibacterial, anti-allergic , and hepatoprotective properties
  • Currently, their biological properties are subject to important biomedical research.
  • Based on these activities, flavonoids are considered today as potential therapeutics agents against a wide variety of diseases.

 

What are flavonoids and where are they?

  • Flavonoids are a large number of natural products of low molecular weight, most with structure phenyl-benzo-y-pyran (or phenyl-y-chromone). They are plant secondary metabolism products.
  • In plants, flavonoids are found in the free state, or more frequently as flavonolic glycosides.
  • The flavonolic glycosides are generally soluble in water, while their aglycone, the non-associated glycoside moiety, are the only slightly.
  • There is a relationship between the biological activity of flavonoids and their chemical structure, particularly hydroxylation patterns in the rings of the structure.
