Metabolite Identification
Common NameProcyanidin B8
DescriptionProcyanidin B8 belongs to the class of organic compounds known as catechins. Catechins are compounds containing a catechin moiety, which is a 3,4-dihydro-2-chromene-3,5.7-tiol. Procyanidin B8 has been detected, but not quantified in, several different foods, such as acorns (Quercus), common grapes (Vitis vinifera), fruits, lingonberries (Vaccinium vitis-idaea), and red raspberries (Rubus idaeus). This could make procyanidin B8 a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Procyanidin B8.
