13. Prenylated flavonoids from maclura tinctoria fruits
A phytochemical investigation of Maclura tinctoria fruits yielded five flavonoids, including one prenylated flavonol (licoflavonol) and four prenylated isoflavones (wighteone, derrone, alpinum isoflavone, and 6-(2,2-dimethyl-2H-chromen-6-yl)-2-(1-hydroxy-1-methylethyl)-2,3-dihydro-5H-furo[3,2-g]chromen-5-one). The structures of the isolates were established

14. Genetic variability of isoflavones in the USDA red clover core collection
Red clover is one of the most utilized forage in agriculture and contains many of the isoflavones known for their human health benefits. The objectives of this study were: i) to quantify, using HPLC analysis, isoflavones in 77 accessions from the USDA core collection and a Brazilian line; ii) to verify possible relationships depending on their origin, improv

15. Development of an analytical method to quantify total isoflavones in phytotherapic capsules using high-performance liquid chromatography
Isoflavones can be found in grains and leaves of soybean. Currently, these are sold in pharmacies as phytotherapic capsules. Isoflavones have been recommended by doctors, especially for women, due to their ability to relieve menopause symptoms, among other benefits. However, no method exists for the official control of isoflavone content in capsules sold in

16. Soybean extracts enriched with free isoflavones promote nitric oxide synthesis and affect the proliferation of breast adenocarcinoma cells
Although soybean isoflavones naturally accumulate in their conjugated forms, the beneficial effects on human health of soybean-containing foods have been credited to their aglycone forms. In the present study we analyzed the effects of a chemical agent, sodium nitroprusside (SNP), in eliciting the exudation of non-conjugated isoflavones from intact soybean s

17. In vitro isoflavonoid production and analysis in natural tetraploid Trifolium pratense (red clover) calluses
Isoflavones are polyphenolic phytoestrogens, predominantly found in leguminous plants. Trifolium pratense L., Fabaceae (red clover), is rich in isoflavones that possess estrogenic activity due to their similar molecular structure and effectiveness in preventing health conditions such as menopause, osteoporosis, cardiovascular disease, hypertension and hormon

18. Estudo fitoquímico e avaliação da atividade anti-inflamatória de Aeschynomene fluminensis vell. (Fabaceae)
Phytochemical investigation of Aeschynomene fluminensis leaves and branches led to isolation of the flavonoid glycosides kaempferol 3,7-di-O-α-L-rhamnopyranoside, kaempferol 7-O-α-L-rhamnopyranoside, kaempferol 3-O-apiofuranosil-7-O- rhamnopyranoside, quercitin 3-O-α-L-rhamnopyranoside, quercitin 3-O-arabinofuranoside, 8-β-D-glucopyranosyl 4',5,7-trihydr

19. Caracterização química e avaliação da atividade antioxidante e citotóxica do extrato da soja (Glycine max) biotransformada pelo fungo Aspergillus awamori / Chemical characterization and evaluation of the antioxidant and cytotoxic activity of the soybean (Glycine max) extract biotransformed by the Aspergillus awamori
A soja (Glycine max) contém uma variedade de compostos com comprovada atividade biológica, tais como as isoflavonas, que estão presentes em diferentes formas, glicosiladas e agliconas. Além disso, a soja contém uma grande quantidade de proteínas, que são consideradas fontes de peptídeos bioativos. As isoflavonas agliconas, daidzeína e genisteína, p

21. Effects of genetics and environment on isoflavone content of soybean from different regions of Brazil.
The effects of genetics and environmental factors on isoflavone content of soybean (Glycine max L.) cultivars grown in different locations in Brazil in 1993/94 were evaluated. Seeds of different cultivars were analised by high performance liquid chromatography (HPLC). In Rio Grande do Sul (RS), Paraná (PR), and Mato Grosso do Sul (MS) States, a significant

24. Activity of beta-glucosidase and levels of isoflavone glucosides in soybean cultivars affected by the environment.
The enzyme B-glucosidade hydrolyses the isoflavone glucosides developing aglycones, which are compounds with anticancer effects, that are also related with the astringency observed in soybean flavor. Due to the importance of this enzyme, a study was carried out to determine B-glucosidade activity in soybean (Glycine max (L.) Merrill) cultivars with different
