Abstract
Flavonoids often exhibit broad bioactivity but low solubility and bioavailability, limiting their practical applications. The transglycosylated materials α-glucosyl rutin (Rutin-G) and α-glucosyl hesperidin (Hsp-G) are known to enhance the dissolution of hydrophobic compounds, such as flavonoids and other polyphenols. In this study, the effects of these materials on flavone solubilization were investigated by probing their interactions with flavone in aqueous solutions. Rutin-G and Hsp-G prepared via solvent evaporation and spray-drying methods were evaluated for their ability to dissolve flavones. Rutin-G had a stronger flavone-solubilizing effect than Hsp-G in both types of composite particles. The origin of this difference in behavior was elucidated by small-angle X-ray scattering (SAXS) and nuclear magnetic resonance analyses. The different self-association structures of Rutin-G and Hsp-G were supported by SAXS analysis, which proved that Rutin-G formed polydisperse aggregates, whereas Hsp-G formed core-shell micelles. The observation of nuclear Overhauser effects (NOEs) between flavone and α-glucosyl materials suggested the existence of intermolecular hydrophobic interactions. However, flavone interacted with different regions of Rutin-G and Hsp-G. In particular, NOE correlations were observed between the protons of flavone and the α-glucosyl protons of Rutin-G. The different molecular association states of Rutin-G or Hsp-G could be responsible for their different effects on the solubility of flavone. A better understanding of the mechanism of flavone solubility enhancement via association with α-glucosyl materials would permit the application of α-glucosyl materials to the solubilization of other hydrophobic compounds including polyphenols such as flavonoids.

Abstract
Background Curcumin (CUR) is a functional ingredient from the spice turmeric. It has attracted considerable attention recently, owing to its diverse biological activities. However, curcumin has low water solubility, which limited its applications. Some sugar molecules were found to be able to solubilise poorly water-soluble compounds by forming micelles in aqueous solutions. Purpose To improve the water solubility and oral absorption of CUR, using a non-nutritive natural sweetener, namely, Mogroside V (Mog-V). Methods A solid dispersion of CUR in Mog-V was prepared using a solvent evaporation method. The solid dispersion was characterised by using X-ray diffraction and differential scanning calorimetry. The solid dispersion can dissolve in water to form micelles with a diameter of ~160 nm, which were characterised by using dynamic light scattering. To find out the mechanism of solubilisation, the aggregation behaviour of Mog-V molecules in aqueous solution was investigated using nuclear magnetic resonance spectroscopy. Finally, oral absorption of CUR in the solid dispersion was evaluated using a rodent model. Results A solid dispersion was formed in a ratio of 1 CUR to 10 Mog-V by weight. Upon dissolution into water, CUR laden micelles formed via self-assembly of Mog-V molecules, which increased the solubility of CUR by nearly 6000 times compared with pure CUR crystals. In rats, the solid dispersion increased the oral absorption of CUR by 29 folds, compared with CUR crystals. In terms of solubilisation mechanism, it was found that Mog-V self-assembled into micelles with a core-shell structure and CUR molecules were incorporated into the hydrophobic core of the Mog-V micelles. Conclusion Mog-V can form a solid dispersion with CUR. Upon dissolution in water, the Mog-V in the solid dispersion can self-assemble into micelles, which solubilise CUR and increase its oral absorption.

Abstract
Transglycosylation has been used to modify the physicochemical properties of original compounds. As a result, transglycosylated compounds can form molecular aggregates in size ranges of a few nanometers in an aqueous medium when their concentrations exceed a specific level. Incorporating these hydrophobic compounds has been observed to enhance the solubility of hydrophobic compounds into aggregate structures. Thus, this review introduces four transglycosylated compounds as food additives that can enhance the solubility and oral absorption of hydrophobic compounds. Here, transglycosylated hesperidin, transglycosylated rutin, transglycosylated naringin, and transglycosylated stevia are the focus as representative substances. Significantly, we observed that amorphous formations containing hydrophobic compounds with transglycosylated compounds improved solubility and oral absorption compared to untreated hydrophobic compounds. Moreover, combining transglycosylated compounds with hydrophilic polymers or surfactants enhanced the solubilizing effects on hydrophobic compounds. Furthermore, the enhanced solubility of hydrophobic compounds improved their oral absorption. Transglycosylated compounds also influenced nanoparticle preparation of hydrophobic compounds as a dispersant. This study demonstrated the benefits of transglycosylated compounds in developing supplements and nutraceuticals of hydrophobic compounds with poor aqueous solubility.

Abstract
α-Glycosyl rutin (Rutin-G), composed of a flavonol skeleton and sugar groups, is a promising non-polymeric additive for stabilizing amorphous drug formulations. In this study, the mechanism of the stabilization of the amorphous state of carbamazepine (CBZ) by Rutin-G was investigated. In comparison with hypromellose (HPMC), which is commonly used as a crystallization inhibitor for amorphous drugs, Rutin-G significantly stabilized amorphous CBZ. Moreover, the dissolution rate and the resultant supersaturation level of CBZ were significantly improved in the CBZ/Rutin-G spray-dried samples (SPDs) owing to the rapid dissolution property of Rutin-G. Differential scanning calorimetry measurement demonstrated a high glass transition temperature (Tg) of 186.4°C corresponding to Rutin-G. The CBZ/Rutin-G SPDs with CBZ weight ratios up to 80% showed single glass transitions, indicating the homogeneity of CBZ and Rutin-G. A solid-state NMR experiment using 13C- and 15N-labeled CBZ demonstrated the interaction between the flavonol skeleton of Rutin-G and the amide group of CBZ. A 1H-13C two-dimensional heteronuclear correlation NMR experiment and quantum mechanical calculations confirmed the presence of a possible hydrogen bond between the amino proton in CBZ and the carbonyl oxygen in the flavonol skeleton of Rutin-G. This specific hydrogen bond could contribute to the strong interaction between CBZ and Rutin-G, resulting in the high stability of amorphous CBZ in the CBZ/Rutin-G SPD. Hence, Rutin-G, a non-polymeric amorphous additive with high Tg, high miscibility with drugs, and rapid and pH-independent dissolution properties could be useful in the preparation of amorphous formulations.

Abstract
Water soluble α-glycosylated rutin (4G-α-D-glucopyranosyl rutin, monoglucosyl rutin, MR) was used in this study to evaluate its ability to reduce abdominal visceral fat (AVF). We conducted a study examining 66 healthy Japanese men and women with a body mass index of ≥23 and <30 kg/m2 for 8 weeks. The subjects were randomly assigned to groups via computer random numbers as follows: MR200 group (MR 200 mg/day), MR400 group (MR 400mg/day), or placebo group. The primary outcome was change in the AVF area after 8 weeks of intervention. The secondary outcomes were effects of MR on total fat and subcutaneous fat of umbilical area, lipid-related markers, and subjective symptoms. The per-protocol set analysis involved 18 subjects in the placebo group (7 males and 11 females), 20 subjects in the MR200 group (8 males and 12 females), and 20 subjects in the MR400 group (8 males and 12 females). AVF area in both the MR200 and MR400 groups was reduced at week 8, with changes from the baseline (week 0) significantly higher than the placebo group. Additionally, the MR400 group reported improved subjective symptoms concerning being "worried about abdominal fat" at week 4 compared with the placebo group. These results indicate that the consumption of MR (200 and 400 mg/day) for 8 weeks reduced AVF. PRACTICAL APPLICATION: Monoglucosyl rutin, an enzymatically modified form of rutin, is a highly stable and water-soluble flavonoid widely used in food and beverages to prevent oxidation. The present clinical study demonstrated that it may improve overall health by reducing abdominal visceral fat.

Abstract
BACKGROUND Rutin is a flavonol glycoside that can be found in a wide variety of vegetables and has activity, anti-cancer, anti-inflammatory and anti-diabetic properties. OBJECTIVE This study investigated the effect of rutin oral administration on Wistar rats submitted to hepatic hyperplasia after partial hepatectomy (PH). METHODS To achieve this, we considered the analysis of hepatic hyperplastic and plasma biochemical activity of Wistar rats, subjected to treatment with rutin 40 mg/kg/day for 10 days in group 1 (G1) or saline in group 2 (G2), followed by partial hepatectomy. RESULTS The results indicated an increase in the number of mitoses after 24 hours and 48 hours (P=0.0022 and P=0.0152, respectively) of PH in the group that received rutin, as well as an increase in AST serum levels after 24 hours (P=0.0159) and 48 hours (P=0.0158) and alkaline phosphatase after 24 hours (P=0.015) in the same group, in relation to the respective controls. The group that received rutin showed a more evident variation than the control group when comparing the 24 hour and 48 hour results regarding AST, number of mitoses and number of apoptosis (P<0.005). CONCLUSION It was concluded that rutin intervened in hepatic hyperplasia after 24 hours and 48 hours of PH, favoring hepatic hyperplasia.

Abstract
Folic acid a synthetic form of folate, is the oxidized form of folate which acts as a coenzyme in one carbon transfer reactions required in the biosynthesis of DNA and RNA and its deficiency could be related to diseases such as neural tube defects, Alzheimer's disease, pregnancy complications and cancer. Inulin is a polydisperse polysaccharide comprising mostly of fructosyl fructose units. An oxidized derivative of this inulin was prepared and used as a complexing agent for folic acid to obtain a polysaccharide bound folic acid conjugate. The aldehyde content and degree of oxidation of the oxidized inulin were determined by acid-base titrations. All the products were characterized by sophisticated spectroscopic and thermal methods of analysis. Release studies of folic acid from conjugates were carried out in different pH media and the results demonstrate the pH-sensitive behavior of the inulin-based delivery system towards the controlled release of folic acid.

Abstract
This study investigates the permeance and rejection efficiencies of different dyes (Rhodamine B and methyl orange), folic acid and a protein (bovine serum albumin) using graphene oxide composite membrane. The ultrathin separation layer of graphene oxide (thickness of 380 nm) was successfully deposited onto porous polyvinylidene fluoride-polyacrylic acid intermediate layer on nonwoven support layer using vacuum filtration. The graphene oxide addition in the composite membrane caused an increased hydrophilicity and negative surface charge than those of the membrane without graphene oxide. In the filtration process using a graphene oxide composite membrane, the permeance values of pure water, dyes, folic acid and bovine serum albumin molecules were more severely decreased (by two orders of magnitude) than those of the nonwoven/polyvinylidene fluoride-polyacrylic acid composite membrane. However, the rejection efficiency of the graphene oxide composite was significantly improved in cationic Rhodamine B (from 9% to 80.3%) and anionic methyl orange (from 28.3% to 86.6%) feed solutions. The folic acid and bovine serum albumin were nearly completely rejected from solutions using either nonwoven/polyvinylidene fluoride-polyacrylic acid or nonwoven/polyvinylidene fluoride-polyacrylic acid/graphene oxide composite membrane, but the latter possessed anti-fouling property against the protein molecules. The separation mechanism in nonwoven/polyvinylidene fluoride-polyacrylic acid membrane includes the Donnan exclusion effect (for smaller-than-pore-size solutes) and sieving mechanism (for larger solutes). The sieving mechanism governs the filtration behavior in the nonwoven/polyvinylidene fluoride-polyacrylic acid/graphene oxide composite membrane.

Abstract
Folic acid, a synthetic form of folate, is a water-soluble vitamin that is essential during periods of rapid cell division and growth. However, it decomposes upon ultraviolet irradiation to form inactive photoproducts. In this study, the protective effect and mechanisms of antioxidants, including cinnamic acids, flavonoids, catechol and its derivatives, stilbenes, p-benzoquinone and its derivatives, isoprenoids, curcumin, oleic acid, and linoleic acid, against folic acid photodecomposition were investigated by using fluorescence and absorbance spectroscopy, high-performance liquid chromatography, and antioxidant assay. It was found that antioxidants could inhibit or delay the folic acid decomposition in varying degrees, among which caffeic acid was the most effective. The increase in its remarkable antioxidant efficiency and absorbance in the UVA region during irradiation contributed to its effective protection. This finding could be useful for the protection of photolabile components in food and other uses.

Abstract
We successfully prepared folic acid (FA) nanoparticles with excellent dispersibility and photostability using a combination of bead milling and freeze-drying with transglycosylated naringin (Naringin-G), a newly developed transglycosylated food additive. Poly-vinyl pyrrolidon (PVP) was used for comparison with Naringin-G. Water dispersibility and photostability of the freeze-dried formulations were assessed. The dispersibility and physicochemical properties of nanoparticle formulations were evaluated using dynamic light scattering, powder X-ray diffraction (PXRD), and small-angle X-ray scattering (SAXS). Results indicated that the median particle size of FA in the slurry bead milled with Naringin-G decreased notably with time and fell below 100 nm after milling for 300 min. Further, FA nanoparticles with Naringin-G were stable without aggregation following re-dispersion of freeze-dried FA formulations in water. Contrarily, the addition of PVP did not prevent the aggregation of FA nanoparticles following re-dispersion of freeze-dried FA formulations. Solid structures of freeze-dried FA formulations with Naringin-G or PVP were assessed using PXRD and SAXS. PXRD patterns of all freeze-dried formulations highlighted broadening and weakening of peaks, indicating a decrease in FA crystallinity following bead milling, regardless of the additive concentration of Naringin-G and PVP. The scattering intensity profiles of FA formulations with PVP dramatically decreased after milling, whereas FA formulations with Naringin-G did not exhibit changes in SAXS patterns. FA formulations with Naringin-G registered faster enhancement in release rate than PVP in pH 1.2 buffer solutions. The release rate of freeze-dried FA formulation with Naringin-G exhibited at least five-fold enhancement when compared to untreated FA. FA formulation with Naringin-G was stable to photodegradation under fluorescent light. Naringin-G prevented photodegradation of FA due to its antioxidant effect and scavenged radicals. These findings indicated that freeze-dried FA formulation with Naringin-G can improve its water-dispersibility and photodegradation due to the effectiveness of Naringin-G as a dispersant and cryoprotectant.

Abstract
In this study, three novel flavonoid composite materials, created by combining an aglycone [quercetin (QUE), hesperetin (HES) or naringenin (NAR)] with monoglucosyl rutin (MGR), were designed to test for improved radioprotectivity compared with that provided by administration of MGR alone. Aglycone in the MGR-composite state was highly soluble in water, compared with aglycone alone dissolved in dimethyl sulfoxide or distilled water. The antioxidant activity of the three flavonoid composites was as high as that of MGR only. Next, the cytotoxicity test after 30 min treatment of an MGR composite showed a clear reduction in cell viability and suggested that a rapid introduction of aglycone into cells had taken place. In addition, QUE/MGR and HES/MGR composites strongly scavenged intracellular reactive oxygen species (ROS) induced by X-ray irradiation as well as MGR alone did. However, in the colony-formation assay using irradiated Chinese hamster ovary (CHO) cells, the HES/MGR composite showed a stronger radioprotective effect than MGR alone did, but the QUE/MGR composite showed no additional protective effect compared with the control. Furthermore, it was revealed that QUE and QUE/MGR composite treatment had the effect of reducing the glutathione (GSH) content in cells, and that QUE showed a stronger inhibition of PARP activity compared that of HES and NAR. Our data demonstrated that when designing a flavonoid composite as a radioprotective agent, it was necessary to select an appropriate aglycone, considering not only its antioxidant ability but also its inhibitory effect on cell recovery or DNA repair after radiation injury.

Abstract
Normal tissue damage from ionizing radiation during radiotherapy is a major concern in cancer treatment. Tea polyphenols (TPs) have been shown to reduce radiation-induced damage in multiple studies, but their pharmacological application is still limited due to poor bioavailability. The present study was aimed at to increase the TPs bioavailability by nanoformulation by using BSA as the matrix and chitosan as the external shell. Encapsulated TPs nanoparticles were spherical in size and promoted TPs stability in normal and gastrointestinal conditions without losing antioxidant activity. Oral administration of nanoparticles for 3 days prior to irradiation exposure has been shown to protect mice from hematological injuries that result in the reduction of radiation-induced lethality. TPs reduce radiation-induced oxidative damage and apoptosis by restoring the redox status through the Nrf2-ERK pathway and reducing Bax expression, respectively. Regarding potency, encapsulated TPs have shown a significantly higher level of radioprotection than TPs, suggesting that TP nanoparticles can be explored as valuable radioprotective and pharmacotherapeutic agent.

Abstract
Many polyphenols that contain more than two phenolic hydroxyl groups are natural antioxidants and can provide health benefits to humans. These polyphenols include, for example, oleuropein, hydroxytyrosol, catechin, chlorogenic acids, hesperidin, nobiletin, and isoflavones. These have been studied widely because of their strong radical-scavenging and antioxidative effects. These effects may contribute to the prevention of diseases, such as diabetes. Insulin secretion, insulin resistance, and homeostasis are important factors in the onset of diabetes, a disease that is associated with dysfunction of pancreatic β-cells. Oxidative stress is thought to contribute to this dysfunction and the effects of antioxidants on the pathogenesis of diabetes have, therefore, been investigated. Here, we summarize the antioxidative effects of polyphenols from the perspective of their radical-scavenging activities as well as their effects on signal transduction pathways. We also describe the preventative effects of polyphenols on diabetes by referring to recent studies including those reported by us. Appropriate analytical approaches for evaluating antioxidants in studies on the prevention of diabetes are comprehensively reviewed.
