   Proanthocyanidins are included in the pycnogenols, a plant polyphenol chemical group, whose physical, chemical and biological properties have been studied in numerous works (see more especially J. Masquelier, J. Michaud, J. Laparra, and M. C. Dumon, Internat. J. Vit. Nutr. Res. 1979, 49, 307-311).
