lignans การใช้

• Secoisolariciresinol and matairesinol were the first plant lignans identified in foods.
• The plant lignans are precursors of the enterolignans ( mammalian lignans ).
• The plant lignans are precursors of the enterolignans ( mammalian lignans ).
• Chemical constituents include the lignans schisandrin, deoxyschisandrin, gomisins, and pregomisin.
• Cleistanthin A and cleistanthin B are arylnaphthalide lignans.
• When polymerized, " p "-coumaryl alcohol forms lignin or lignans.
• The potency is traced to three components : fiber, lignans and alpha-linolenic acid.
• It is a precursor of mammal lignans which are produced in the colon from chemicals in foods.
• Pinoresinol and lariciresinol are more recently identified plant lignans that contribute substantially to the total dietary lignan intakes.
• The substance is one of a group of compounds called lignans, which are known for their antiviral action.
• Pinoresinol, along with other plant lignans, are converted into enterolignans by intestinal microflora in the human body.
• In addition to magnolol, related lignans occur in the extracts including honokiol, which is an isomer of magnolol.
• In the table below are a few examples of the 22 analyzed species and the 24 lignans identified in this study.
• The family contains a wide range of benzylisoquinoline compounds ( alkaloids ) and lignans such as furofuran, flavones and flavonols and some proanthocyanidins.
• Lignans have also been identified as phytoestrogens, although they are not flavonoids . but also occurring elsewhere, e . g . on various forages.
• These compounds have highly divergent structures including alkaloids, anthraquinones, flavonoids, iridoids, triterpenoids, sterols, lignans and a number of other compounds.
• A number of plant lignans are metabolized to the enterolignans ( enterodiol and enterolactone ) that can potentially reduce the risk of certain cancers and cardiovascular diseases.
• Leaves, roots, stem, bark and berries of this genus contain lignans ( e . g . phyllanthin and hypophyllanthin ) and a variety of other phytochemicals.
• LIGNANS : These plant compounds found in the hull act as as weak form of estrogen and appear to protect the body from hormonal cancers-- including breast cancer.
• Plant lignans associated with high fiber foods such as cereal brans and beans are the principal precursor to mammalian lignans which have an ability to bind to human estrogen sites.
