Flavonoids: Distribution, Chemistry And Pharmacological Role In Health And Disease

Abstract

The flavonoids are one of the most widespread groups of plant substances (I). They are ubiquitous in vascular plants and occur in the root, bark, leaf, fruit, flower, pollen and seeds(l'6). About 2% of the total carbon photosynthesised are converted to Flavonoids which in turn contribute to the myriad bright colours in plant tissues (3,7). These compounds are the largest group of plant phenols and more than 4000 types have been isolated and identified in vascular plants (I)
