- 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).1987, Masquelier, Jack, US Patent 4,698,360 - Plant extract with a proanthocyanidins content as therapeutic agent having radical scavenger effect and use thereof:
