Thearubigins are polymeric polyphenols that are formed during the enzymatic oxidation of tea leaves. This process is referred to as "fermentation" in the tea industry, but is technically not a true fermentation. Thearubigins are formed when theaflavins are condensed with epitheaflavic acids (formed by the oxidation of gallic acid).[1]
