Prodelphinidin
Prodelphinidin is a name for the polymeric tannins composed of gallocatechin.[1][2][3]
Prodelphinidin can be found in the pomegranate, in green tea leaves[4] and in Myrica rubra.[5]
Prodelphinidin B3 [gallocatechin-(4α→8)-catechin] and prodelphinidin B9 can be isolated in beer.[6] Prodelphinidin C2 [gallocatechin-(4α→8)-gallocatechin-(4α→8)-catechin] can be isolated in malt.[7]
