Common NameEpicatechin-(2beta->7,4beta->8)-epicatechin-(4beta->8)-epicatechin
DescriptionEpicatechin-(2beta->7,4beta->8)-epicatechin-(4beta->8)-epicatechin, also known as cinnamtannin b-1, belongs to the class of organic compounds known as biflavonoids and polyflavonoids. These are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3'-C3''', and C6-C8''. Epicatechin-(2beta->7,4beta->8)-epicatechin-(4beta->8)-epicatechin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, epicatechin-(2beta->7,4beta->8)-epicatechin-(4beta->8)-epicatechin has been detected, but not quantified in, several different foods, such as ceylon cinnamons, fruits, herbs and spices, and lingonberries. This could make epicatechin-(2beta->7,4beta->8)-epicatechin-(4beta->8)-epicatechin a potential biomarker for the consumption of these foods. A proanthocyanidin found in Cinnamomum cassia and Cinnamomum zeylanicum.
