Procyanidin B3 is a B type proanthocyanidin. Procyanidin B3 is a catechin dimer (catechin-(4α→8)-catechin).
Natural occurrences
It can be found in red wine,[1] in barley,[2][3] in beer,[4] in peach[5] or in Jatropha macrantha, the Huanarpo Macho.[6]
Health effects
It has been identified as a hair-growth stimulant.[2]
Chemical synthesis
Molar equivalents of synthetic (2R,3S,4R or S)-leucocyanidin and (+)-catechin condense with exceptional rapidity at pH 5 under ambient conditions to give the all-trans-[4,8]- and [4,6]-bi-[(+)-catechins] (procyanidins B3, B6) the all-trans-[4,8:4,8]- and [4,8:4,6]-tri-[(+)-catechins] (procyanidin C2 and isomer).[7]
