Common Name

Cinnamtannin II

Description

Cinnamtannin II 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''. Cinnamtannin II is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Cinnamtannin II has been detected, but not quantified in, chinese cinnamons and herbs and spices. Cinnamtannin II is found in Areca catechu , Malus pumila , Pseudotsuga menziesii, Rhaphiolepis umbellata and Theobroma cacao. This could make cinnamtannin II a potential biomarker for the consumption of these foods.
