pycnogenol

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

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

b) An antioxidant dietary supplement containing such an extract

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.
