Phytoestrogens represent a family of plant compounds such as isoflavones, flavones and lignans. A variety of these plant compounds have been identified in various human body fluids. A wide range of commonly consumed foods contains appreciable amounts of these different phytoestrogens, viz. soy products are particularly good sources of isoflavones and lignans. Accumulating evidences from molecul...
Purpose: Lignans such as secoisolariciresinol diglucoside in flaxseed, are metabolizes to bioactive mammalian lignans of END and ENL. Because mammalian lignans have chemical structural similarity to the natural estrogen, they are thought to behave like selective estrogen receptor modulators and therefore have anticancer effect against hormone-related cancers. We isolated a series of lignan comp...
BACKGROUND Mother's diet during pregnancy is important, since plant lignans and their metabolites, converted by the intestinal microflora to enterolignans, are proposed to possess multiple health benefits. Aim of our study was to investigate whether a dietary intervention affects lignan concentrations in the serum of pregnant women. METHODS A controlled dietary intervention trial including 10...
Five known lignans, (+)-pinoresinol (1), (+)-8-hydroxypinoresinol (2), (-)-dehydrodiconiferyl alcohol (3), (+)-trans-dehydrodiconiferyl alcohol (4), and (-)-olivil (5), were isolated from the roots of Rosa multiflora for the first time. Their structures were determined using spectroscopic data.
The regioselective demethoxylation and dehalogenation of dihalogenated dibenzocyclooctadiene lignans derivatives were realized in a one-step reaction with excellent yields in the sodium and t-butanol reaction system.
High intake of phytoestrogen lignans has been found to be associated with decreased risk of esophageal adenocarcinoma in our previous population-based case-control study in Sweden. To further evaluate this possible association, we tested the hypothesis of an inverse association between dietary lignan intake and risk of esophageal and gastric adenocarcinoma using a prospective design. In a popul...
