Metabolite Identification
Common NameProcyanidin B3
DescriptionProcyanidin B3, also known as C-(4a,8)-C, 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''. Thus, procyanidin B3 is considered to be a flavonoid. Procyanidin B3 is found, on average, in the highest concentration within a few different foods, such as quinces (Cydonia oblonga), barleys (Hordeum vulgare), and broad beans (Vicia faba) and in a lower concentration in redcurrants (Ribes rubrum), teas (Camellia sinensis), and medlars (Mespilus germanica). Procyanidin B3 has also been detected, but not quantified in, several different foods, such as breakfast cereal, tartary buckwheats (Fagopyrum tataricum), avocados (Persea americana), garden tomato (var.), and cereals and cereal products. This could make procyanidin B3 a potential biomarker for the consumption of these foods. Procyanidin B3 is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Procyanidin B3.
