NCIt definition : A class of natural flavonoids derived from the dried leaves of the plant Camellia
sinensis (tea) and related plants with potent antioxidant properties. Theaflavins
are polymers derived from natural catechins which are oxidized upon drying of the
plant leaf. Flavonoids such as theaflavins neutralize free-radical species and increase
the activity of detoxifying phase II enzymes in the liver. In animal studies, theaflavins
have been shown to exhibit antitumor effects by inducing tumor cell apoptosis, arresting
cell division, inhibiting cancer cell invasion, and blocking growth factor-induced
angiogenesis. Black tea contains the highest concentrations of theaflavins. (NCI04);
