1. Production of Hydrolysate of Okara Protein Concentrate with High Antioxidant Capacity and Aglycone Isoflavone Content
Abstract This work aimed to evaluate the enzymatic hydrolysis of okara protein concentrate with respect to degree of hydrolysis (DH) in order to obtain a protein hydrolysate with high antioxidant capacity and aglycones isoflavone content. A central composite rotatable design was carried out to evaluate the influence of temperature (40 to 70°C), enzyme:subst

2. Isoflavone-aglycone fraction from Glycine max: a promising raw material for isoflavone-based pharmaceutical or nutraceutical products
ABSTRACT The present work was designed to obtain a fraction containing high concentration of isoflavone-aglycones from Glycine max (L.) Merr., Fabaceae, named isoflavone enriched-fraction, from a dry extract containing isoflavones-glycosides. A simple and low cost method was proposed: extraction of isoflavone glycosides from the G. max dry extract with a pro

3. 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

4. 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

5. 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

6. Beta-glucosidase activity of soybean epicotyls in germination.
Isoflavones are compounds with benefits for human health and they are the mainly forms of glycosides in vegetables. ?-glucosidase (?-D-glucoside glucohydrolase, E.C.3.2.1.21) hydrolyses ?-D-glucosides releasing glucose and forming aglycone isoflavones. The aglycone isoflavone is the most bioavailable form of the glycosides. ?-glucosidase that converts glycos

7. Degradation of the Isoflavone Biochanin A and Its Glucoside Conjugates by Ascochyta rabiei
Strains of Ascochyta rabiei which are pathogenic to chickpea (Cicer arietinum L.) readily catabolized the main chickpea isoflavone biochanin A (5,7-dihydroxy-4′-methoxyisoflavone). 3′-Hydroxylation and O-demethylation reactions led to the isoflavones pratensein, genistein, and orobol, which were rapidly further degraded. Dihydrogenistein and p-hydroxyphe

8. Suppression of an Isoflavonoid Phytoalexin Defense Response in Mycorrhizal Alfalfa Roots.
Isoflavonoids and steady-state mRNA levels of phenylalanine ammonia-lyase, chalcone isomerase, and isoflavone reductase were followed during a rapid, nearly synchronous infection of alfalfa (Medicago sativa L.) roots by the vesicular arbuscular fungus Glomus intraradices (Schenck & Smith) to test whether previously indicated suppression of the host defense r
