LIGNANS

A lignan is a polyphenolic compound that occurs naturally in some plants, rye, barley, seeds, fresh fruits, broccoli, and some berries. In recent years research has shown that a significant amount of lignans are also present in trees, especially the knots of the wood. (87)(38)

It is known that the accumulation of lignans in the core of trees is important for the durability and longevity of the species. (61) Lignans’ roles in the longevity of trees may be the key to their nutritional benefits.

Major plant lignans known are secoisolariciresinol, matairesinol, pinoresinol, sesamin and hydroxymatairesinol. Similar to isoflavonoids (most commonly soybeans) lignans are phytoestrogens.

Isoflavonoids and lignans in various foods can be measured via gas chromatography (63), with soybeans and flaxseed having the highest lignan contents of plants studied.

NORWEGIAN SPRUCE EXTRACT

Lignans were first discovered in trees over 100 years ago. The norwegian spruce extract, collected from the knotwood of the tree (Picea Abies) is thought to be one of nature's highest concentration of lignans available (50) (38)

Knots in trees have been shown to have 5-10% dry weight of lignans, much higher than ordinary stemwood, with the Norwegian Spruce containing 6-24% of lignans, this being 50 to 100 times higher than in normal wood (54)

Flaxseed is also known to have the highest concentration of lignans in the plant world, however Chromatographic analysis of lignans shows that Norwegian Spruce knotwood extract has between 10 and 20 times more lignans than flaxseed (50)(61).

Norwegian Spruce knotwood lignans are primarily composed of 7-hydroxymatairesinol (HMR). But is also possesses a large amount of other lignans as well

Using more recent measurements techniques, it was found that HMR is also the major lignan source in wheat, oat, barley and bran, but still in much smaller amounts than those found in Norwegian Spruce. (53)
