Jack Arthur Masquelier, Professor Emeritus of the University of Bordeaux, France, is one of the early pioneers who greatly contributed to shedding light on the structure, chemistry, nomenclature, determination, isolation, and applications of the flavanols compounds which, today, are presented as MASQUELIER's® Original OPCs and MASQUELIER's French Pine Bark Complex.
