If someone wanted to learn about polyphenols they should study bio-chemistry , because polyphenols are polymers of catechin and epicatechin, belonging of the family of condensed tannins.

No.Tea contains polyphenols (aka catechins), which are a specific type of tannin. Green Tea contains more of these substances (30-42% of the extractable solids) than Black Tea or Oolong Tea. Oolong Tea has 8-20% catechin content, and Black Tea is about halfway between Green Tea and Oolong Tea in catechin content. Tea does not contain Tannic Acid. See articles "Green tea composition, consumption, and polyphenol chemistry" at PubMed (National Center for Biotechnology Information); and "The Chemistry of Tea" at HerbalGram (American Botanical Council).
