Many studies have shown that a relationship exists between the consumption of tea and potential disease prevention properties which may be due to high polyphenol content (4, 5). Polyphenols are secondary metabolites of plants that are used in their defense system against severe environments such as ultraviolet radiation and pathogens. These compounds are generally classified into flavonoids, phenolic acids, lignans and stilbenes. Flavonoids, the most ubiquitous polyphenols, are benzo-γ-pyrone derivatives consisting of phenolic and pyrane rings, and are classified into flavanols, flavones, flavonols, flavanones, isoflavones and anthocyanidins.
