Description
Procyanidin B6 is a proanthocyanidin consisting of two molecules of (+)-catechin joined by a bond between positions 4 and 6' in alpha-configuration. Procyanidin B6 is isolated from leaves and fruit of cowberry Vaccinium vitis-idaea and other plants. It can also be found in grape seeds and in beer. It has a role as a metabolite. It is a hydroxyflavan, a proanthocyanidin and a biflavonoid. It is functionally related to a (+)-catechin.
Procyanidin B6 has been reported in Quercus miyagii, Nelumbo nucifera, and Salix sieboldiana with data available.
