The lignans are a large group of low molecular weight polyphenols found in plants, particularly seeds, whole grains, and vegetables. [1] The name derives from the Latin word for "wood". [2] Lignans are precursors to phytoestrogens. [1] [3] They may play a role as antifeedants in the defense of seeds and plants against herbivores. [4]

Lignans are a group of natural compounds found in plants, particularly in seeds, grains, and legumes. They are classified as phytoestrogens, which means they have a similar structure to the hormone estrogen found in humans. However, unlike estrogen, lignans do not stimulate the same biological responses in the body.

Lignans are phenolic dimers found in plants, serving as the building blocks for lignin in cell walls. They are converted into mammalian lignans through fermentation in the colon, with major examples being enterodiol and enterolactone.

Current evidence highlight the bioactive properties of lignans as human health-promoting molecules. Thus, dietary intake of lignan-rich foods could be a useful way to bolster the prevention of chronic illness, such as certain types of cancers and cardiovascular disease. Keywords: lignans, diet, antioxidants, health promotion, chronic diseases. 1.

We reviewed lignan physiology and lignan intervention and epidemiological studies to determine if they decreased the risks of cardiovascular disease in Western populations.

Lignans are vascular plant secondary metabolites, with widespread occurrence in the plant kingdom, and which are ascribed a wide range of physiological functions, positively affecting human health [1].

2023年3月14日 · Lignans are phytoestrogens with estrogenic or anti-estrogenic activity. In the following table is a list of food stuffs and beverages and their total lignan con

Plant lignans are the principal source of phytoestrogens in the diets of people who do not typically consume soy foods. The daily phytoestrogen intake of postmenopausal women in the US was estimated to be less than 1 mg/day, with 80% from lignans and 20% from isoflavones (86) .

2020年12月1日 · Lignans are large group of polyphenols that are formed by the coupling of two coniferyl alcohol residues. Based on their origin, lignans are broadly grouped into plant lignans such as isolariciresinol, secoisolariciresinol diglucoside, lariciresinol, and matairesinol; and mammalian lignans such as enterodiol and enterolactone.

A class of dibenzylbutane derivatives which occurs in higher plants and in fluids (bile, serum, urine, etc.) in man and other animals. These compounds, which have a potential anti-cancer role, can be synthesized in vitro by human fecal flora. (From Singleton and Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)
