Menopause (New York, N.Y.), 19(8), 894-903 (2012-03-15)
Phytoestrogens, which consist mainly of isoflavones, lignans, and coumestans have estrogenic and anti-inflammatory properties. Previous research suggests that higher dietary or supplemental intakes of isoflavones and lignans are related to better cognitive performance in middle-aged and older women. We conducted

Flavonoids, secondary plant metabolites which mainly have a polyphenolic structure, play an important role in plant-microbe communications for nitrogen-fixing symbiosis. Among 10 polyphenolic compounds isolated from soybean roots in our previous study, coumestrol showed the highest antioxidant activity. In this

Menopause (New York, N.Y.), 20(3), 305-314 (2013-02-26)
Although reduction of vasomotor symptoms (VMS; hot flashes and night sweats) has been reported in postmenopausal women who used isoflavones, a clear dose response has not been shown, has largely not been reported for perimenopausal women, and has largely only

Bioassay-guided fractionation of the EtOAc-soluble extract of Pueraria lobata based on the inhibition of Aβ-induced toxicity in PC12 cells resulted in the isolation of four known active compounds, genistein (8), biochanin A (9), sissotrin (10), and puerol B (11). Of

Nutrition journal, 10, 105-105 (2011-10-08)
Phytoestrogens may be associated with a variety of different health outcomes, including outcomes related to reproductive health. Recently published data on phytoestrogen content of a wide range of foods provide an opportunity to improve estimation of dietary phytoestrogen intake. Using
