(organic chemistry) Any of a group of flavonoids extracted from the bark of pine trees, especially proanthocyanidins.

*:On the other hand, pycnogenols , widely found in old empirical antiscorbutic remedies, seem more appropriate...
*1987 , Masquelier; Jack, "US Patent 4,698,360 - Plant extract with a proanthocyanidins content as therapeutic agent having radical scavenger effect and use thereof"
*: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).
*1993 , Hans J. Kugler, David Steinman, Life extenders and memory boosters!
*:He has found that pycnogenols not only prevent free radical damage to internal organs but also help prevent skin wrinkling.
*1994 , Lerner; Sheldon, "US Patent 5,470,874 - Ascorbic acid and proanthocyanidine composition for topical application to human skin "
*:The second embodiment of the invention includes the pine bark extract known as proanthocyanidine, also known as pycnogenol .

*:Masquelier (34,35) was perhaps one of the first to recognize the potential of this class of compounds, referring to them as pycnogenols or proanthocyanidols.
*1998 , Joe M. Elrod, Supplements for Fibromyalgia , page 26
*:Human trials have shown that the flavonoids of pycnogenol can prevent peripheral hemorrhage, swelling of legs due to water retention, diabetic retinopathy, and high blood pressure.
*1999 , Corinne T. Netzer, Corrine T. Netzer's Big Book of Miracle Cures
*:As study after study has shown, nutrients such as grape seed extract and pycnogenols are great all-around helpers for capillaries, veins, and arteries.

*:The extent of the antioxidant potential of pycnogenol in vivo is unclear.

*:Masquelier developed a process to extract these compounds — both from pine bark (in 1951) and from grape seeds (1970). He used the term pycnogenol to refer to this whole family of OPCs.

*:As histidine decarboxylase inhibitors, pycnogenols lower the histamine level in the aortic endothelium...

*:This may be due to the phenomenon in which pycnogenol at high concentrations blocks the filter channels

*:Among three fractions of pycnogenol , fraction 3 (oligomeric procyanidins) significantly enhanced the potent EDR activity.
