Lignans and Human Health

Critical Reviews in Clinical Laboratory Sciences, 2007
This review focuses on the possible role in human health of the consumption of lignan-rich foods. Most of the plant lignans in human foods are converted by the intestinal microflora in the upper part of the large bowel to enterolactone and enterodiol, called mammalian or enterolignans.

Musts with Increased Lignan Content Through Addition of Lignan Extracts

Food and Bioprocess Technology, 2017
Red and white grape musts were enriched with 7-hydroxymatairesinol (HMR), which is the main lignan contained in spruce knots. Lignan enrichment was achieved by adding a spruce knot ethanol extract. Enriched musts were stored for 12 months and during storage must samples were periodically analyzed for HMR and alpha-conidendrin content, antioxidant ...

Polycyclic Spiro Lignans and Biphenyl Tetrahydrofuranone Lignans from Gymnotheca involucrata

Planta Medica, 2016
Four rare polycyclic spiro lignans (1-4) and four new biphenyl tetrahydrofuranone lignans (5-8) were isolated from the whole plant of Gymnotheca involucrata. The structures of the new compounds were elucidated on the basis of detailed spectroscopic analysis and the absolute configuration of 1 was confirmed by single crystal X-ray diffraction.

The Lignans

1962
Publisher Summary This chapter discusses lignans. Haworth introduced the generic term lignans for a family of optically active plant products that are characterized by the β, γ-dibenzylbutane skeleton. In lignans, the phenyl nuclei are substituted, the side chains exist in various states of oxidation, and in some cases, the C-skeleton is further ...

Phytotoxic lignans ofLeucophyllum frutescens

Natural Toxins, 1999
Bioassay-guided fractionation of the hexane:ethyl acetate (1:1) extract of the leaves of Leucophyllum frutescens (Berl.) I.M.Johnst (Scrophulariaceae) led to the isolation of its phytotoxic constituents diayangambin (1), epiyangambin (2), diasesartemin (3) and epiashantin (4). Phytotoxicity was demonstrated as inhibition of seed germination of Agrostis

Lignans from Chilean Propolis

Journal of Natural Products, 1998
Three new (1, 3, 4) and two known lignans (2 and 5) were isolated from Chilean propolis. Compound 1 was identified as a trimeric coniferyl alcohol acetate and 3 as the diastereomer of the dimeric coniferyl alcohol acetate 2. Compound 4 was identified as a dihydrobenzofuran lignan aldehyde, which was isolated together with the related known acetate 5.

In Vitro Metabolism of Plant Lignans:  New Precursors of Mammalian Lignans Enterolactone and Enterodiol

Journal of Agricultural and Food Chemistry, 2001
The metabolism of the plant lignans matairesinol, secoisolariciresinol, pinoresinol, syringaresinol, arctigenin, 7-hydroxymatairesinol, isolariciresinol, and lariciresinol by human fecal microflora was investigated to study their properties as mammalian lignan precursors.
