What is Flaxseed Hull Extract producedin Hunan Nutramax Inc.?

Secoisolariciresinol diglycoside, or SDG, is a plantlignan most notably found in flaxseed (linseed). SDG is classified as aphytoestrogen since it is a plant-derived, nonsteroid compound that possessesestrogen-like activity. SDG has weak estrogenic activity. The level of SDG inflaxseed typically varies between 0.6% and 1.8%.

Lignans are one of the two major classes ofphytoestrogens; the other class is the isoflavones. Plant lignans arepolyphenolic substances derived from phenylalanine via dimerization ofsubstituted cinnamic alcohols. Mammalian lignans are lignans derived from plantlignans. For example, following ingestion, SDG is converted to the aglyconesecoisolariciresinol, which is then metabolized to the mammalian lignansenterolactone and enterodiol. Most of the effects of oral SDG are mediated byenterolactone and enterodiol.

The molecular formula of SDG is C32H46O16, and itsmolecular weight is 686.71 daltons. The aglycone of SDG is also known as 2,3-bis (3-methoxy-4-hydroxybenzyl) butane-1, 4-diol. Enterolactone is also knownas trans-2, 3-bis [(3-hydroxylphenyl) methyl]-butyrolactone. It is representedby the following structural formula:
