Metabolite Identification
Common NameTheasinensin B
DescriptionTheasinensin B, also known as egcg-egc dimer, belongs to the class of organic compounds known as complex tannins. These are tannins made of a catechin bound to a gallotannin or elagitannin. Theasinensin B is found, on average, in the highest concentration within a few different foods, such as teas (Camellia sinensis), red tea, and herbal tea and in a lower concentration in green tea and black tea. This could make theasinensin b a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Theasinensin B.
