Biflavonoids and polyflavonoids 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-(4beta->6)-catechin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Epicatechin-(2beta->7,4beta->8)-epicatechin-(4beta->8)-epicatechin-(4beta->6)-catechin can be found in lingonberry, which makes epicatechin-(2beta->7,4beta->8)-epicatechin-(4beta->8)-epicatechin-(4beta->6)-catechin a potential biomarker for the consumption of this food product.
