theaflavin

Theaflavin is a polyphenolic flavonoid that has been found in black tea and has diverse biological activities, including antioxidant, anticancer, anti-inflammatory, and antiviral properties

Theaflavin-3-gallate (Theaflavine-3-Gallate) can play a role in decreased intestinal cholesterol absorption via inhibition of micelle formation. Theaflavin-3-gallate has anticancer and apoptotic effects in non-small cell lung carcinoma, it acts as prooxidants and induce oxidative stress, with carcinoma cells more sensitive than normal fibroblasts.

Theaflavin 3,3'-digallate, a major polyphenol found in black tea, is an inducer of oxidative stress which has anti-inflammatory and cancer chemopreventive actions, it reduces tumor angiogenesis by downregulating HIF-1αand VEGF.

Theaflavin-3'-Gallate (Theaflavin 2B) usually comes from the leaves of Camellia sinensis (L.) O. Kuntze. Theaflavin-3'-gallate, act as prooxidants and induce oxidative stress, with carcinoma cells more sensitive than normal fibroblasts.

Theaflavin digallate and lactic acid together could reduce herpes simplex virus transmission.

Neotheaflavin (from black tea) inhibits pancreatic lipase.

Isotheaflavin is a natural product.
