The Potential Protective Effects of Phenolic Compounds against Low-density Lipoprotein Oxidation

Exploiting the beneficial effects of Salvia officinalis L. extracts in human health and assessing their activity as potent functional regulators of food microbiota

Salvia officinalis L. has attracted scientific and industrial interest due to its pharmacological properties. However, its detailed phytochemical profile and its correlation with beneficial effects in the human microbiome and oxidative stress remained elusive. To unveil this, S. officinalis was collected from the region of Epirus and its molecular identity was verified with DNA barcoding. Phytochemical profile for both aqueous and ethanol-based extracts was determined by high-pressure liquid chromatography-tandem mass spectrometry and 103 phytochemicals were determined. The effect of S. officinalis extracts as functional regulators of food microbiota by stimulating the growth of Lacticaseibacillus rhamnosus strains and by suppressing evolution of pathogenic bacteria was verified. Furthermore, we recorded that both extracts exhibited a significant cellular protection against H2O2-induced DNA damage. Finally, both extracts exhibited strong inhibitory effect towards LDL oxidation. This study provides a comprehensive characterization of S. officinalis on its phytochemical components as also its potential impact in human microbiome and oxidative stress.

Yerba Mate as a Protectant against Lipoproteins Oxidation

Oxidative modification of low-density lipoproteins (LDL) and high-density lipoproteins (HDL) are important factors determining cardiovascular risk. This study investigated the antioxidant mechanisms and potential protective effect of a hydroethanolic extract of yerba mate (Ilex paraguaiensis; EHEM) on the in vitro oxidation of LDL and HDL. EHEM was found to possess ferric reducing power, DPPH free radical scavenging capacity, metal chelating activity, and NO radical scavenging activity. In addition, EHEM reduced the lipoperoxidation induced by α,α'-Azodiisobutyramidine dihydrochloride (AAPH) in HDL and LDL at all tested concentrations. In this study, we demonstrate the antioxidant properties of yerba mate and its phytochemical compounds. These properties may effectively prevent the in vitro oxidation of LDL and HDL molecules, a phenomenon linked to the pathogenesis of atherosclerosis.

Enhancement of Antioxidant and Anti-Glycation Properties of Beeswax Alcohol in Reconstituted High-Density Lipoprotein: Safeguarding against Carboxymethyllysine Toxicity in Zebrafish

The antioxidant and anti-inflammatory abilities of beeswax alcohol (BWA) are well reported in animal and human clinical studies, with a significant decrease in malondialdehyde (MDA) in the blood, reduced liver steatosis, and decreased insulin. However, there has been insufficient information to explain BWAs in vitro antioxidant and anti-inflammatory activity owing to its limited solubility in an aqueous buffer system. Herein, three distinct reconstituted high-density lipoproteins (rHDL) were prepared with palmitoyloleoyl phosphatidylcholine (POPC), cholesterol, apolipoprotein A-I (apoA-I), and BWA at molar ratios of 95:5:1:0 (rHDL-0), 95:5:1:0.5 (rHDL-0.5), and 95:5:1:1 (rHDL-1) and examined for antioxidant and anti-glycation effects. A rHDL containing BWA, precisely rHDL-1, displayed a remarkable anti-glycation effect against fructose (final 250 mM), induced glycation of HDL, and prevented proteolytic degradation of apoA-I. Also, BWA incorporated rHDL-0.5, and rHDL-1 displayed substantial antioxidant activity by inhibiting cupric ion-mediated low-density lipoprotein (LDL) oxidation. In contrast to rHDL-0, a 20 and 22% enhancement in ferric ion reduction ability (FRA) and paraoxonase (PON) activity was observed in HDL treated with rHDL-1, signifying the effect of BWA on the antioxidant activity enhancement of HDL. rHDL-1 efficiently inhibits Nε-carboxylmethyllysine (CML)-induced reactive oxygen species (ROS) generation and apoptosis in zebrafish embryos, consequently improving embryo survivability and developmental deformities impaired by the CML. The dermal application of rHDL-1 to the CML-impaired cutaneous wound of the adult zebrafish inhibited ROS production and displayed potent wound-healing activity. Conclusively, incorporating BWA in rHDL significantly enhanced the anti-glycation and antioxidant activities in rHDL via more stabilization of apoA-I with a larger particle size. The rHDL containing BWA facilitated the inherent antioxidant ability of HDL to suppress the CML-induced toxicities in zebrafish embryos and ameliorate CML-aggravated chronic wounds in adult zebrafish.

Metabolomic analysis and ecofriendly enrichment of sunflower meal extract

BACKGROUND

The presence of phenolic compounds in sunflower is well reported in the literature; however, knowledge is scarce when it comes to the composition of other secondary metabolites in this species and their by-products. This work evaluated, for the first time, the phytochemical composition of sunflower meal produced in Brazil. A combination of mixture design and central composite rotatable design 2³ models was then applied to maximize the recovery of bioactive compounds using ecologically friendly solvents and concentrating by applying activated carbon, a sustainable adsorbent. The product of this extraction-concentration was also evaluated by an untargeted metabolomic approach using ultra-performance liquid chromatography coupled to mass spectrometry.

RESULTS

A diverse and abundant profile of phenolic compounds was obtained from Brazilian sunflower meal: in total, 51 natural products were tentatively identified, 35 of which for the first time in sunflower. The sorption capacity of the activated charcoal, in the optimized process conditions, was effective in the separation and concentration of minority secondary metabolites. The ecofriendly extract proved to be enriched in plumberoside, p-coumaric acid, and alkaloids.

CONCLUSIONS

Investigation of the phytochemical profile of sunflower meal produced in Brazil pointed to several secondary metabolites reported for the first time in sunflower samples, including phenolic compounds, alkaloids, and terpenes. The use of activated charcoal in an alkaline medium as an adsorbent for the concentration of these phytochemicals, from an aqueous extract, generated a potentially cost-effective, ecofriendly extract, enriched in minor metabolites, indicating a possible innovative way to selectively obtain these compounds from sunflower meal. © 2022 Society of Chemical Industry.

Antioxidant Effect of Chrysanthemum morifolium (Chuju) Extract on H2O2-Treated L-O2 Cells as Revealed by LC/MS-Based Metabolic Profiling

Chrysanthemum has a long history of being used to attenuate various oxidative stress-related discomforts and diseases; however, its mechanisms remain unclear. In this study, the antioxidant effect of chrysanthemum aqueous extract was investigated, and the potential mechanisms were explored via a metabolomics study. Chrysanthemum extract could significantly inhibit hydrogen peroxide (H₂O₂)-mediated cell death in L-O2 hepatocytes. Propidium iodide staining and annexin V-PI dual staining revealed that the antioxidant effect of chrysanthemum extract was related to the relief of cell cycle arrest and inhibition of non-apoptotic cell damage. The activities of antioxidant enzymes including superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) were also upregulated by chrysanthemum extract. Through metabolomics studies, it was found that chrysanthemum extract mainly targeted the arginine synthesis pathway and purine metabolism pathway, in which antioxidation-related endogenous substrates including L-arginosuccinate, citrulline and inositol monophosphate were significantly upregulated by chrysanthemum extract. These results indicated that chrysanthemum extract can antagonize oxidative stress through multiple pathways and have potential therapeutic applications.

Molecular Determinants of the Cardiometabolic Improvements of Dietary Flavanols Identified by an Integrative Analysis of Nutrigenomic Data from a Systematic Review of Animal Studies

SCOPE

Flavanols are important polyphenols of the human diet with extensive demonstrations of their beneficial effects on cardiometabolic health. They contribute to preserve health acting on a large range of cellular processes. The underlying mechanisms of action of flavanols are not fully understood but involve a nutrigenomic regulation.

METHODS AND RESULTS

To further capture how the intake of dietary flavanols results in the modulation of gene expression, nutrigenomics data in response to dietary flavanols obtained from animal models of cardiometabolic diseases have been collected and submitted to a bioinformatics analysis. This systematic analysis shows that dietary flavanols modulate a large range of genes mainly involved in endocrine function, fatty acid metabolism, and inflammation. Several regulators of the gene expression have been predicted and include transcription factors, miRNAs and epigenetic factors.

CONCLUSION

This review highlights the complex and multilevel action of dietary flavanols contributing to their strong potential to preserve cardiometabolic health. The identification of the potential molecular mediators and of the flavanol metabolites driving the nutrigenomic response in the target organs is still a pending question which the answer will contribute to optimize the beneficial health effects of dietary bioactives.

Development of an UHPLC-diode arrays detector (DAD) method for the analysis of polydatin in human plasma

A new chromatographic method by Ultra High Performance Liquid Chromatographic (UHPLC) technology, has been developed and validated for the determination of polydatin and resveratrol, as potential metabolite, in human plasma. After the optimization of the chromatographic conditions, the method has been validated on spiked human plasma samples. The optimized extraction allowed to obtain analytes recovery up to 98.48 ± 4.03 %. Then, the isocratic elution in reversed phase mode, provides the separation of polydatin and resveratrol in less than 10.0 min. Chromatographic analysis was performed on a C18, 10 cm x 3.0 mm, 2.7 μm stationary phase, by using triethanolamine phosphate solution (0.1 M, pH = 3.7) and ACN 85:15 (v/v) as mobile phase at a flow rate of 0.5 mL/min. The UV detector was set at 306 nm for the analysis of both polydatin and resveratrol. The limit of detection (LoD) and the limit of quantification (LoQ) for polydatin in plasma samples were found to be 7.82 ± 0.38 nM and 26.06 ± 1.28 nM respectively. The method was found to be accurate and precise with a coefficient for intra- and inter-day variation below 5 %. All the reported data demonstrate how the developed method is rapid and sensitive. Moreover, results of the analysis of plasma samples, obtained from orally treated volunteers with nutritional supplements containing polydatin, have shown the method to be suitable for the pharmacokinetic characterization of polydatin and resveratrol, as metabolite, in humans.

In vitro antioxidant and antidiabetic activity of essential oils encapsulated in gelatin-pectin particles against sugar, lipid and protein oxidation and amylase and glucosidase activity

The in vitro antioxidant and antidiabetic activities of Oliveria decumbens, Thymus kotschyanus, Trachyspermum ammi, and Zataria multiflora essential oils incorporated into gelatin-pectin composite were investigated. The gas chromatography-mass spectrometry characterization revealed that thymol (1.2%-86.4%), carvacrol (3.2%-52.4%), gamma-terpinene (0.0%-12.7%), para-cymene (3.2%-5.2%), geraniol (0.0%-14.5%), and spathulenol (0.0%-13.6%) are the major constituents of the essential oils. Gelatin-pectin composite incorporated with the essential oils exhibited acidic pH (2.40-3.04), low conductivity (265-278 µS/cm), low surface tension (19.0-23.5 mN/m), low Newtonian viscosity (23.7-28.5 mPa.s), negative zeta-potential (14.2-16.9 mV), and nanoscale particle size (313-336 nm). These rheological properties result in the production of globular gelatin-pectin nanoparticles with a size range of 500-700 nm. The FTIR spectra of gelatin-pectin and gelatin-pectin-essential oils to some extent were similar, suggesting the noncovalent interactions between them. Gelatin-pectin composite incorporated with the essential oils displayed antiglucose oxidation (130-150 µg/ml) antilipid peroxidation (120-130 µg/ml), antiprotein oxidation (150-168 µg/ml), and antiprotein glycation (145-170 µg/ml) as well as antiamylase (216-230 µg/ml), and antiglucosidase (212-238 µg/ml) activity. The essential oils strongly improved the antioxidant capacity of the gelatin-pectin composite so strongly which can be recommended as a natural compound for oxidative stress management.

In vitro and ex vivo anti-diabetic and anti-hyperglycemic properties of Zataria multiflora essential oil

The underlying mechanism involved in the onset of many diseases such as diabetes is oxidative stress. Zataria multiflora has a very high antioxidant power that can be used in the antioxidant therapy of the diabetes symptom. The in vitro antioxidant and anti-diabetic capacity of Zataria multiflora essential oil (ZMEO) incorporated in dendrosome against glucose oxidation, lipid oxidation, protein oxidation, and protein glycation was analyzed. The ex vivo antioxidant capacity of dendrosomal ZMEO were explored against hyperglycemia (HG)-induced oxidative stress. Inhibition of oxidative stress markers; NADH oxidase (NOX), nuclear respiratory factor 2 (NRF2) and nuclear factor kappa B (NF-kB) were examined. Dendrosomal-ZMEO displayed low conductivity, low surface tension, low zeta-potential, nanoscale particle size and low viscosity that suggest dendrosomal-ZMEO could remain stable in biological fluids. FTIR spectra of dendrosomal-ZMEO indicated the non-covalent interactions between dendrosome and ZMEO and the entrapment of ZMEO droplets in the dendrosome network. Dendrosomal-ZMEO displayed good anti-glucose oxidation, anti-lipid peroxidation, anti-protein oxidation, and anti-protein glycation activity. Dendrosomal ZMEO strongly reduced intracellular hydrogen peroxide and NOX expression and activity in HG-treated macrophages while increased superoxide dismutase (SOD) and catalase (CAT) expression and activity in a synergistic manner. HG-treated murine macrophages showed an increased level of NF-kB expression while the decreased level of NRF2 expression compared to controls. The anti-diabetic activity of ZMEO by sequestering hydrogen peroxide and down-regulation of NOX activity is a recommended mechanism for diabetes and oxidative stress. The effect of ZMEO on decreasing NF-kB and increasing in NRF2, transcription factors involved in oxidative stress and hyperglycemia, may imply its clinical application.

In Vitro Biological Properties of Solanum sessiliflorum (Dunal), an Amazonian Fruit

Solanum sessiliflorum is an Amazonian fruit (cubiu) that has been domesticated since pre-Colombian era. It is also used in folk medicine to treat some clinical conditions. This investigation chemically characterized and analyzed the in vitro antioxidant and antitumoral effect of a cubiu pulp/seed hydroalcoholic extract. Cubiu extract was chemically characterized by high-performance liquid chromatography with diode array detector (HPLC-DAD), its antioxidant capacity measured by 2.2-diphenyl-1-picrylhydrazyl (DPPH) assay, and the following complementary in vitro protocols were performed: (1) cytoprotective effect of cubiu on human peripheral blood mononuclear cells (PBMCs) exposed to H₂O₂, a genotoxic and procarcinogen molecule; (2) effect of cubiu on low density lipoproteins oxidation; and (3) cytotoxic and antiproliferative effect on breast (MCF-7) and colorectal (HT-29) cancer cell lines. Biochemical and flow cytometry analyses were conducted in these protocols. Cubiu extract presented high concentrations of caffeic and gallic acids, beta-carotene, catechin, quercetin, and rutin, and its antioxidant capacity was confirmed. Cubiu attenuated H₂O₂ cytotoxicity on PBMCs, presented lowering effect on LDL oxidation, and induced mortality and proliferative inhibition of colorectal cancer cells. In cancer cells, cubiu extract at 10 μg/mL showed similar effects to 5-fluorouracil chemo drug reducing its viability and frequency of S-phase, indicating that cells are undergoing mitosis. In summary, despite the limitations of in vitro protocols, our results suggest that cubiu has several biological properties that affect human health.

The antioxidant screening of potential materials for drugs based on 6-nitro-1,2,4-triazoloazines containing natural polyphenol fragments

The course of viral diseases is accompanied by excessive generation of active oxygen metabolites, so the effectiveness of treatment can be improved by combining antiviral and antioxidant therapy. There was a screening of antioxidant properties of 6-nitro-1,2,4-triazoloazine-modified fragments of natural polyphenols (catechol, pyrogallol, phloroglucinol, resorcinol) which are potential dual-action combination preparations. Screening was carried out using various approaches: the study of redox transformations by cyclic voltammetry, determination of antioxidant capacity with oxidizing agents of a radical and non-radical nature by the potentiometric method using potassium hexacyanoferrate (III) and optical methods (the Folin assay and the DPPH assay). It has been established that molecules obtained by conjugation of polyphenols with heterocycles exhibit antioxidant properties. The exception is adducts of triazolodiazines with resorcinol. A decrease in the antioxidant ability of synthesized adducts relative to initial polyphenols has been noted. The antioxidant capacity has been studied at a number of temperatures (25 °C, 37 °C), and the reaction half-life has been determined. The correlation of antioxidant capacity by a potentiometric assay with the Folin assay was R = 0.71; by a potentiometric assay with the DPPH assay was R = 0.67. Leader compounds have been identified.

Antioxidant and Pro-Oxidant Properties of Carthamus Tinctorius, Hydroxy Safflor Yellow A, and Safflor Yellow A

(1) Carthamus Tinctorius L. (safflower) is extensively used in traditional herbal medicine. (2) The aim of this study was to investigate the bioactive properties of polyphenol extracts from flowers of Carthamus Tinctorius (CT) cultivated in Italy. We also evaluated the properties of two bioactive water-soluble flavonoid compounds, hydroxy safflor yellow A (HSYA) and safflor yellow A (SYA), contained in Carthamus Tinctorius petals. (3) The total polyphenol content was 3.5 ± 0.2 g gallic acid equivalent (GAE)/100 g, flavonoids content was 330 ± 23 mg catechin equivalent (CE)/100 g in the flowers. The extract showed a high antioxidant activity evaluated by oxygen radical absorbance capacity (ORAC) and 2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging assays. In addition, flower extract, SYA, and HSYA were able to reduce the susceptibility of low-density lipoprotein to copper-induced lipid peroxidation. In order to investigate the bioactive properties of flower extract, SYA, and HSYA we also studied their modulatory effect of oxidative stress on human dermal fibroblasts (HuDe) oxidized by tert-butyl hydroperoxide (t-BOOH). The CT extract at concentrations ranging from 0.01–20 μg GAE/mL of polyphenols, exerted a protective effect against t-BOOH triggered oxidative stress. At higher concentration the extract exerted a pro-oxidant effect. Similar results have been obtained using HSYA and SYA. (4) These results demonstrate a biphasic effect exerted by HSYA, SYA, and flower extracts on oxidative stress.

CGA restrains the apoptosis of Aβ25-35-induced hippocampal neurons

Background: Chlorogenic acid (CGA) has anti-oxidant and anti-inflammatory effects, but the study on its role in Alzheimer's disease (AD) models remains rare. Here, the effects of CGA on β-amyloid protein (Aβ)-induced cell models were investigated, aiming to provide a direction for Aβ-induced AD.Material and methods: Hippocampal neurons were separated from newborn Sprague-Dawley (SD) rats and identified by immumofluorescence method. Hippocampal neurons were processed with Aβ_25-35 after pre-treatment CGA. MTT assay was used for detecting viability of treated cells. The activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA) and lactate dehydrogenase (LDH) of treated hippocampal neurons were determined by corresponding kits. Flow cytometry analysis assessed the apoptosis and mitochondrial membrane potential (MMP) in hippocampal neurons after treatment. The expressions of proteins related to apoptosis and endoplasmic reticulum stress (ERS) were measured by western blot (WB) analysis.Results: Immumofluorescence method showed that the Aβ_25-35 induction models were successfully constructed. CGA increased the viability and decreased the apoptosis rate of Aβ_25-35-induced hippocampal neurons. Decreasing activities of LDH and MDA, and raised contents of SOD and GSH-Px were appeared in Aβ_25-35-induced cells that pre-treated with CGA. Moreover, CGA also enhanced MMP intensity of hippocampal neurons induced by Aβ_25-35. In WB analysis, CGA reversed the promoting effect of Aβ_25-35 on the expressions of proteins related to pro-ERS and pro-apoptosis.Conclusion: CGA restrained the apoptosis of Aβ_25-35-induced hippocampal neurons via improving the anti-oxidant capacity, mitochondrial injury and ERS state of cells, which may provide a direction for AD.

Amaranth (Amaranthus cruentus L.) and canola (Brassica napus L.) oil impact on the oxidative metabolism of neutrophils in the obese patients

CONTEXT

Amaranth and canola oils have been used traditionally. Amaranth has been identified as being of interest because of its outstanding nutritive value. Amaranth oil is a rich source of highly unsaturated fats and so could be a valuable dietary alternative for individuals affected with obesity. Reactive oxygen species (ROS) are postulated to be involved in systemic inflammation and oxidative stress. Activated polymorphonuclear neutrophils (PMNs) generate high amounts of reactive oxygen species.

OBJECTIVE

Our study investigates the impact of amaranth and canola oils supplementation on oxidative metabolism in patients with obesity. We hypothesized that, due to its lipid-lowering and antioxidant properties, amaranth and canola oil would protect against oxidative stress.

MATERIALS AND METHODS

We tested 19 obese patients [body mass index (BMI) = 41.1 ± 7.8 kg/m², (mean ± SD)]. The protocol consisted of two stages: a run-in phase of 2 weeks and an experimental stage - canola or amaranth oil supplementation (20 mL/d) with calorie restriction diet for 3 weeks. The neutrophil oxidative burst was expressed by fluorescence intensity (IF).

RESULTS

The oxidative burst had increased significantly at the end of treatment in both groups IF: (21.4 ± 11.15 vs. 35.9 ± 20.3; mean ± SD) p < 0.05. The levels of IF were significantly higher in neutrophils of patients who received canola oil (41.05 ± 25.3) compared to those who received amaranth oil (28.4 ± 11.8) p < 0.05.

CONCLUSIONS

Canola oil exerts possible effects on oxidative burst activity in neutrophils in vivo conditions.

The predictive utility of the plant phylogeny in identifying sources of cardiovascular drugs

CONTEXT

Cardiovascular disease (CVD) is the number one cause of death globally, responsible for over 17 million (31%) deaths in the world. Novel pharmacological interventions may be needed given the high prevalence of CVD.

OBJECTIVE

In this study, we aimed to find potential new sources of cardiovascular (CV) drugs from phylogenetic and pharmacological analyses of plant species that have experimental and traditional CV applications in the literature.

MATERIALS AND METHODS

We reconstructed the molecular phylogeny of these plant species and mapped their pharmacological mechanisms of action on the phylogeny.

RESULTS

Out of 139 plant species in 71 plant families, seven plant families with 45 species emerged as phylogenetically important exhibiting common CV mechanisms of action within the family, as would be expected given their common ancestry: Apiaceae, Brassicaceae, Fabaceae, Lamiaceae, Malvaceae, Rosaceae and Zingiberaceae. Apiaceae and Brassicaceae promoted diuresis and hypotension; Fabaceae and Lamiaceae had anticoagulant/thrombolytic effects; Apiaceae and Zingiberaceae were calcium channel blockers. Moreover, Apiaceae, Lamiaceae, Malvaceae, Rosaceae and Zingiberaceae species were found to possess anti-atherosclerotic properties.

DISCUSSION AND CONCLUSIONS

The phylogeny identified certain plant families with disproportionately more species, highlighting their importance as sources of natural products for CV drug discovery. Though there were some species that did not show the same mechanism within the family, the phylogeny predicts that these species may contain undiscovered phytochemistry, and potentially, the same bioactivity. Evolutionary pharmacology, as applied here, may guide and expedite our efforts in discovering sources of new CV drugs.

Effect of Natural Food Antioxidants against LDL and DNA Oxidative Changes

Radical oxygen species formed in human tissue cells by many endogenous and exogenous pathways cause extensive oxidative damage which has been linked to various human diseases. This review paper provides an overview of lipid peroxidation and focuses on the free radicals-initiated processes of low-density lipoprotein (LDL) oxidative modification and DNA oxidative damage, which are widely associated with the initiation and development of atherosclerosis and carcinogenesis, respectively. The article subsequently provides an overview of the recent human trials or even in vitro investigations on the potential of natural antioxidant compounds (such as carotenoids; vitamins C and E) to monitor LDL and DNA oxidative changes.

Multistep Optimization of β-Glucosidase Extraction from Germinated Soybeans (Glycine max L. Merril) and Recovery of Isoflavone Aglycones

Epicotyls from germinated soybeans (EGS) have great potential as sources of endogenous β-glucosidase. Furthermore, this enzyme may improve the conversion of isoflavones into their corresponding aglycones. β-Glucosidase may also increase the release of aglycones from the cell wall of the plant materials. Therefore, the aim of this work was to optimize both the extraction of β-glucosidase from EGS and to further examine its application in defatted soybean cotyledon to improve the recovery of aglycones, which were evaluated by ultra-high performance liquid chromatography (UHPLC). A multistep optimization was carried out and the effects of temperature and pH were investigated by applying a central composite design. The linear effect of pH and the quadratic effect of pH and temperature were significant for the extraction of β-glucosidase and recovery aglycones, respectively. Optimum extraction of β-glucosidase from EGS occurred at 30 °C and pH 5.0. Furthermore, the maximum recovery of aglycones (98.7%), which occurred at 35 °C and pH 7.0⁻7.6 during 144 h of germination, increased 8.5 times with respect to the lowest concentration. The higher bioaccessibility of aglycones when compared with their conjugated counterparts is well substantiated. Therefore, the data provided in this contribution may be useful for enhancing the benefits of soybean, their products, and/or their processing by-products.
