An Innovative Bio-Vehicle for Resveratrol and Tocopherol Based on Quinoa 11S Globulin-Nanocomplex Design and Characterization.

Nanocomplexes, which possess immense potential to function as nanovehicles, can link diverse ligand compounds. The objective of the present study was to design and characterize resveratrol (RSV)- and tocopherol (TOC)-loaded 11S quinoa seed protein nanocomplexes. Firstly, molecular docking was performed to describe the probable binding sites between protein and ligands, and binding energies of -5.6 and -6.2 kcal/mol were found for RSV and TOC, respectively. Isothermal titration calorimetry allowed us to obtain the thermodynamic parameters that described the molecular interactions between RSV or TOC with the protein, finding the complexation process to be exothermic and spontaneous. 11S globulin intrinsic fluorescence spectra showed quenching effects exerted by RSV and TOC, demonstrating protein-bioactive compound interactions. The application of Stern-Volmer, Scatchard, and Förster resonance energy transfer models confirmed static quenching and allowed us to obtain parameters that described the 11S-RSV and 11S-TOC complexation processes. RSV has a higher tendency to bind 11S globulin according to ITC and fluorescence analysis. Secondly, the protein aggregation induced by bioactive compound interactions was confirmed by dynamic light scattering and atomic force microscopy, with diameters <150 nm detected by both techniques. Finally, it was found that the antioxidant capacity of a single 11S globulin did not decrease; meanwhile, it was additive for 11S-RSV. These nanocomplexes could constitute a real platform for the design of nutraceutical products.

Assessment of acute, subacute genetic toxicities and immunomodulatory activity of palm (Trachycarpus fortunei) buds

Ethnopharmacology relevancePalm buds are a natural green resource of the forest, which are not only rich in nutrients but contain a large number of phenolic acids and flavonoids, among other components. It has a variety of biological activities such as antioxidant and uterine smooth muscle stimulation.Aim of the study: To evaluate the safety of palm buds for use as a nutraceutical product and food by evaluating the toxicity, subacute toxicity and genotoxicity of the young palm buds. Also studied for its immune-enhancing activity. Materials and methodsAcute toxicity tests were performed in mice using the maximum tolerance method, and the manifestations of toxicity and deaths were recorded after administration of 10,000 mg/mL for 14 consecutive d (days) of observations. To assess subacute toxicity, mice were treated with palm buds (750, 1500, or 3000 mg/mL) daily for 28 days. The teratogenicity of palm buds was assessed by the Ames test, the mouse bone marrow cell micronucleus test, and the mouse spermatozoa malformation test. In addition, we evaluated the immune-enhancing ability of palm buds by the mouse carbon profile test, delayed-type metamorphosis reaction, and serum hemolysin assay. ResultsIn the acute toxicity study, the Median Lethal Dose (LD50) was greater than 10,000 mg/kg bw in both male and female rats. There were also no deaths or serious toxicities in the subacute study. The no-observed-adverse-effect level (NOAEL) was 3000 mg/kg bw. However, the mice's food intake decreased after one week. The medium and high dose groups had a reducing effect on body weight in mice of both sexes. In addition, the changes in organ coefficients of the liver, kidney and stomach in male mice were significantly higher in the high-dose group (3.23 ± 0.35, 0.75 ± 0.05, 0.57 ± 0.05 g) than in the control group (2.94 ± 0.18, 0.58 ± 0.05, 0.50 ± 0.02 g). Hematological analyses showed that all the indices of the rats in each palm sprout dose group were within the normal range. The results of blood biochemical indicators showed that there was a significant reduction in TP in the blood of male mice in the high-dose group (44.6 ± 7.8 g/L) compared to the control group (58.3 ± 15.1 g/L). In histopathological analysis, none of the significant histopathological changes were observed. The results of the immunological experiment in mice showed that the liver coefficient and thymus coefficient of the high-dose group (8400 mg/kg) were significantly lower than the control group. There was no remarkable difference in auricle swelling between each dose palm bud group (1400, 2800, or 8400 mg/kg) and the control group. The anti-volume number of the high-dose group was significantly increased. ConclusionPalm buds have non-toxic effects in vivo and have little effect on non-specific and cellular immunity in the test mice within the dose range of this experiment. The immunoenhancement in mice is mainly achieved through humoral immunity. In conclusion, our results suggest that palm buds are safe for use as healthcare products and food.

Quantification of the association constant of caffeic acid‐cyclodextrin complex using a novel micro‐conductometric sensor for bitter taste masking of caffeic acid

AbstractCaffeic acid (CA), a member of the hydroxycinnamic acid family, has garnered attention in the medical community for its wide‐ranging health benefits. However, its application in pharmaceutical and nutraceutical products has been hampered by its distinctly bitter taste, which deters many consumers. This study investigates the taste‐masking of caffeic acid (CA) using hydroxypropyl‐β‐cyclodextrin (HP‐β‐CD). A CA micro‐conductometric sensor was developed. This advanced technology demonstrated remarkable sensitivity, capable of detecting CA at concentrations as low as 10−5 M, with a rapid response time between 10 and 50 seconds. The binding constant of the CA‐HP‐β‐CD complex was determined to be 240±24. 1H NMR spectroscopy analysis provided concrete evidence of the formation of a 1 : 1 inclusion complex between CA and HP‐β‐CD. These findings collectively suggest that HP‐β‐CD is highly effective in masking CA's bitterness, thereby significantly enhancing its palatability.

Effects of Strawberry Tree Water Leaf Extract and Arbutin on Biochemical Markers and DNA Integrity in Brain Cells of Lewis Rats.

There is growing evidence that arbutin and plant extracts rich in arbutin, such as extracts of the strawberry tree (Arbutus unedo L.), exert a range of beneficial effects, including cyto- and genoprotective properties. This study evaluated the effects of strawberry tree water leaf extract (STE) and arbutin in the brain tissue of Lewis rats. STE or arbutin were administered per os to male and female rats at a dose of 200 mg/kg body weight/day for 14 or 28 days. Treatment outcomes were evaluated using biochemical markers (lipid peroxidation and the activities of the antioxidative enzymes catalase and superoxide dismutase). The effects of the tested substances on DNA integrity in brain cells were evaluated using the alkaline comet assay. The results suggest a high biocompatibility of both tested substances with rat brain tissue. No significant harmful disturbances were observed in the oxidative/antioxidative status or impairments of DNA integrity in the rat brain cells. Nearly all post-treatment values were within tolerable limits as compared to the matched control rats. Such encouraging findings support further research using other subtle biomarkers to clarify the safety aspects of arbutin and STE prior to the development of specific nutraceutical products.

Comparative study of polyphenol extraction using physical techniques and water as a solvent: a sustainable approach for the valorization of apple pomace.

Apples are among the most commonly cultivated fruits globally. Approximately 65% of annual apple production is transformed into apple juice concentrate generating a large amount of waste material named apple pomace, which includes seeds, skin, and other components. Disposing of apple by-products directly into the environment constitutes a source of environmental pollution due to its high-water content and easily fermentable nature. Apple pomace is rich in polyphenols that can be utilized as active components in cosmetic, nutraceutical, or pharmaceutical products. The present study aims to describe and compare different physical methods for the extraction of polyphenols from apple pomace. Water was used as the extraction solvent in thermal-stirred extraction (TSE), ultrasound-assisted extraction (UAE), and microwave-assisted extraction (MAE). The best extraction conditions were identified in terms of solid to solvent ratio, temperature, power, and time through a kinetic study. The best extraction parameters were compared environmentally on a pilot scale through a life cycle assessment (LCA). All the results demonstrated the MAE is the best technique to extract polyphenol from apple pomace in terms yield and environmental impact proving that it is possible to transform waste into a sustainable source of bioactive ingredients.

Extraction Optimization, Structural Analysis, and Potential Bioactivities of a Novel Polysaccharide from Sporisorium reilianum.

Sporisorium reilianum is an important biotrophic pathogen that causes head smut disease. Polysaccharides extracted from diseased sorghum heads by Sporisorium reilianum exhibit significant medicinal and edible value. However, the structure and biological activities of these novel polysaccharides have not been explored. In this study, a novel polysaccharide (WM-NP'-60) was isolated and purified from the fruit bodies of S. reilianum and aimed to explore the structural characteristics and substantial antioxidant and antitumor properties of WM-NP'-60. Monosaccharide composition determination, periodate oxidation-Smith degradation, 1D/2D-NMR analysis, and methylation analysis revealed that WM-NP'-60 consisted mainly of β-1,6-D-Glcp, β-1,3-D-Glcp, and β-1,3,6-D-Glcp linkages. The antioxidant assays demonstrated that WM-NP'-60 exhibited great activities, including scavenging free radicals, chelating ferrous ions, and eliminating reactive oxygen species (ROS) within cells. The HepG2, SGC7901, and HCT116 cells examined by transmission electron microscopy (TEM) revealed typical apoptotic bodies. Therefore, a novel fungal polysaccharide (WM-NP'-60) was discovered, extracted, and purified in this experiment, with the aim of providing a reference for the development of a new generation of food and nutraceutical products suitable for human consumption.

They were subjected to several evaluation parameters like pre-compression and post-compression studies such as physical appearance, weight variation, hardness and friability. The results of all evaluation parameters of the formulated nutraceutical capsule were within the acceptable limit. Pre-compression studies also had shown satisfactory results. The thickness, hardness, weight variation and friability were found to be in acceptable range. The finding of the present study assures that the formulated nutraceutical capsules meet the quality standards.

Effect of Bidens tripartita leaf supplementation on the organism of rats fed a hypercaloric diet high in fat and fructose

Herbs play an important role in folk medicine, and scientific research has confirmed the properties of their use as an alternative treatment, including the treatment and mild correction of metabolic disorders during disease. Trifid bur-marigold (Bidens tripartita) is a pharmacopoeial herbal raw material that is widely used in clinical practice as an external remedy for skin lesions and as an internal remedy for digestive and respiratory disorders. In this work, the general effect of dried leaves of B. tripartita on physiological activity and metabolic processes in model animals on a high-calorie diet was determined. For the experiment, three groups of 18 male white laboratory rats were formed and fed a hypercaloric diet (increased fat content and 20% fructose solution instead of water) for 27 days, in addition to 0.4% and 4.0% dried leaves of B. tripartita. The consumption of 0.4% and 4.0% of the medicinal plant resulted in a significant delay in the body weight gain and the average daily weight gain of the rats compared to the control group. Dried leaves of B. tripartita in the diet of rats decreased the relative weight of the thymus and increased the relative weight of the brain, and at a dose of 4.0%, increased the relative weight of the lungs and individual large intestines (cecum and colon). Dietary supplementation with B. tripartita caused an increase in globulin concentration and changes in protein coefficient. Blood parameters such as: urea, urea nitrogen, inorganic phosphorus, glucose and bilirubin levels changed depending on the dose. In the general blood test, consumption of dried leaves of B. tripartita caused a decrease in hematocrit, hemoglobin concentration and platelet count, but increased the number of eosinophils. Bidens tripartita at both concentrations significantly increased ALT activity with a corresponding change in the blood De Ritis ratio. The addition of 20 g of B. tripartita leaves to the diet increased alkaline phosphatase activity and decreased alpha-amylase activity, while 200 g increased blood gamma-glutamyltransferase activity. At the end of the experiment, the rats' orientation activity, determined in the open field, changed according to the herb dose consumed: 0.4% leaves caused an increase and 4.0% a decrease. Physical activity was reduced and emotional state increased, regardless of the dose of dried B. tripartita leaves, compared to the control group of animals. The results obtained show that the addition of B. tripartita dried leaves as a dietary supplement to a high-calorie diet is safe, does not cause pathological changes or side effects, and has a significant effect on metabolic processes. This provides theoretical support for the use of B. tripartita dried leaves in the manufacture of nutraceutical and pharmacological products for the correction of metabolic disorders in humans and animals. The doses and duration of their application require further studies.

Effects of a Nutraceutical Treatment on the Intestinal Microbiota of Sled Dogs.

Dog sledding is the main discipline of working dogs on snow, consisting of a team of dogs pulling a sled under the guidance of the owner. To carry out this sport, dogs must have adequate nutrition and vitamin and antioxidant supplementation to ensure that the physical effort is optimal. The present study evaluated the effect that sporting activity and stress have on the canine intestinal microbiota by dividing the dogs into two groups: a control group that did not take any nutraceutical products and the treated group to which a nutraceutical product was administered. The nutraceutical administered in this study is used in all cases of canine intestinal dysbiosis in which it is essential to quickly restore a balanced intestinal microbiota. The results obtained show that in dogs not taking the nutraceutical, there is an increase in bacteria, such as Streptococcus spp. and E. coli, considered enteropathogenic to the detriment of beneficial bacterial species such as Faecalibacterium spp., Turicibacter spp., Blautia spp., Fusobacterium spp., and Clostridium hiranonis. Instead, the group of dogs treated with nutraceutical displays a lower amount of enteropathogenic bacteria and a great increase in the other bacterial species considered beneficial for the animal's health. The results obtained in the present study show that Microbiotal cane® can be used in dogs subject to intense sporting activity by preventing severe alterations at intestinal ecosystem levels by maintaining intestinal bacterial composition as balanced as possible.

Impact of host species on assembly, composition, and functional profiles of phycosphere microbiomes.

Preparation and characterisation of fish skin collagen–chitosan–cinnamon essential oil composite film

SummaryThe composite film with collagen as the main component has been widely used due to its characteristics of non‐toxicity, environmental protection and health. Fish skin, a by‐product of fish, is an excellent source of collagen. Thus, collagen was extracted from an under‐utilised species, Atlantic cod (Gadus morhua) skin, and the composite film of fish skin collagen–chitosan–cinnamon essential oil was prepared by casting. The effects of the ratio of collagen to chitosan (2:8, 4:6, 5:5, 6:4, 8:2) and the concentration of essential oil (0%, 0.1%, 0.2%, 0.3%, and 0.4% (v/v)) on the composite film were studied. The structures of the composite films were analysed using scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR), and X‐ray diffractometry (XRD). The collagen content of Atlantic cod skin is approximately 50.12%, which is significantly higher than that found in basa fish and Nile tilapia (P &lt; 0.05). The content of hydroxyproline was 4.51%. Analyses of tensile strength, elongation at break, water vapor permeability, and water solubility showed Co4Ch6 (Co:Ch = 4:6) had the optimal comprehensive performance, and Co4Ch6–0.2 (Co4Ch6 with 0.2% CEO) had high water resistance in the high‐humidity environment. As the CEO concentration rose, the composite films' infrared absorption bands were enhanced in amplitude, and the XRD peaks were gradually intensified, indicating the internal crystallinity and, thereby, the opacity of the composite films were improved. The bacteriostasis zones Co4Ch6–0.4 against Escherichia coli and Staphylococcus aureus were 2.02 cm and 1.73 cm, respectively. The DPPH radical scavenging rate of Co4Ch6 rose with the increase in CEO concentration, and the DPPH radical scavenging rate of C04Ch6–0.4 was up to 48.56%. Thus, the composite films prepared from fish skin collagen, chitosan, and cinnamon essential oils have outstanding mechanical properties, barrier ability, and antimicrobial activity and are promising for application in food packaging and storage. In addition, the composite films showed a potential antioxidation ability, which might be used as green bioactive films to preserve nutraceutical products.

Coconut: Expanding avenues in processing and an exposition on non-conventional value-added products.

Coconut palm (Cocos nucifera) is a treasured tree of the tropics, with every part put to use. The edible portions are loaded with diverse nutrients and nutraceutical ingredients. While the unique mineral profile of the liquid endosperm, the low-glycemic inflorescence sap (neera) and the medium-chain triglyceride fraction of coconut oil are better recognized, other fractions such as the haustorium remain underexplored. Overall, it is evident that, globally, the present status of coconut value addition is conventional, limited to a handful of products, and novel products hold a promising scope. A massive fraction of global coconut production goes for culinary and religious purposes. In the article, value-added products from coconut are classified into conventional and non-conventional products, with the latter in focus. Based on the part from which it is collected, all products have been categorized as haustorium-based, inflorescence-based, kernel-based and water-based products. For each non-conventional product introduced, its production approach and unique application range are highlighted. Given its health-promoting capabilities, characteristic sensorial attributes, wide application range and technological advancements, coconuts are increasingly being recognized around the world, even in regions that do not cultivate them; this applies to non-food products as well. In the context of value-added products from coconuts, this decade has witnessed a surge in research and commercial interest considering the inclusion of coconut as an ingredient in several food and nutraceutical products. The future will certainly consider regulatory protocols and standards, better documentation of the health impact of coconut-based diets, and the sustainability of coconut production, processing and consumption. © 2024 Society of Chemical Industry.

Study’s Novelty/Excerpt This study evaluates the combined effects of Turmeric, Coriander, and Mint (TCM) leaves on nutritional, functional, and antioxidant properties in polyherbal formulations, showing their superior glucose absorption capacity and antioxidant activity compared to single herbs. The research highlights a significant nutritional shift in the TCM formulation, providing evidence for its enhanced efficacy in nutraceutical applications. These findings show the potential of TCM as a novel botanical candidate for safe and effective pharmaceutical development. Full Abstract Conventional drugs have numerous side effects, toxicity, and microbial resistance, making them unsafe for consumption. Polyherbal formulations are popular due to their potency, low cost, clinical efficacy, safety, and success in chronic conditions. The study aims to evaluate the proximate, vitamin, functional, and antioxidant activity of polyherbal formulations of Turmeric, Coriander, and mint (TCM) leaves as potential botanical candidates for pharmaceutical screening. Thus, addressing these issues and improving access to drugs for individuals by focusing on polyherbal formulations (PHF) is a potential solution. All analyses conducted were determined according to standard assay guidelines. The proximate analysis shows no significant difference among the formulations (p &gt; 0.05), with TCM showing a nutritional profile shift because of the combination of the herbs rather than single herbs. In the vitamin composition, Vitamin A displays a pattern among the formulations, with TC and CM showing higher values than TM and TCM, which are, in turn, better than the single herbs. Vitamin C fluctuates across the formulations. TM displays higher, while T shows the lowest. Vitamin E content remains relatively stable among the formulations with a difference from the single herbs. In the functional properties, GAC displays notable variations among the formulations. TCM exhibits the highest GAC at 14.7 %, indicating its superior ability to absorb glucose. TC, CM, TM, and the single herbs show a comparatively lower GAC value. WAC also varies among the formulations. TCM displays lower WAC compared to TC, TM and CM. The single herbs show the lowest WAC. OAC shows intriguing trends across the formulations. TCM and TC exhibit similar OAC, while CM shows a slightly higher OAC, and TM displays better than single herbs, showing no significant difference (p &gt; 0.05). In the antioxidant Activity, TCM shows lightly higher scavenging activity in 40, 80 and 120 mg/mL concentrations than other formulations. The outcome of this study has led us to conclude that employing safe combinations of these herbal formulations for the production of nutraceuticals is recommended.

Polymethoxyflavones from Kaempferia parviflora rhizomes have been shown to effectively combat aging in skin cells and tissues by inhibiting senescence, reducing oxidative stress, and enhancing skin structure and function. This study assessed the anti-aging effects and safety of standardized K. parviflora extract (BG100), enriched with polymethoxyflavones including 5,7-dimethoxyflavone, 5,7,4'-trimethoxyflavone, 3,5,7,3',4'-pentamethoxyflavone, 3,5,7-trimethoxyflavone, and 3,5,7,4'-tetramethoxyflavone. We evaluated BG100's impact on skin rejuvenation and antioxidant properties using photoaged human 3D full-thickness skin models. The potential for skin irritation and sensitization was also assessed through studies on reconstructed human epidermis and clinical trials. Additionally, in vitro genotoxicity testing was performed following OECD guidelines. Results indicate that BG100 promotes collagen and hyaluronic acid production, reduces oxidative stress, and minimizes DNA damage in photoaged full-thickness 3D skin models. Furthermore, it exhibited non-irritating and non-sensitizing properties, as supported by tests on reconstructed human epidermis and clinical settings. BG100 also passed in vitro genotoxicity tests, adhering to OECD guidelines. These results underscore BG100's potential as a highly effective and safe, natural anti-aging agent, suitable for inclusion in cosmeceutical and nutraceutical products aimed at promoting skin rejuvenation.

Understanding Stabilization of Oil-in-Water Emulsions with Pea Protein─Studies of Structure and Properties.

This study investigates the stability and structure of oil-in-water emulsions stabilized by pea protein. Of the wide range of emulsion compositions explored, a region of stability at a minimum of 5% w/v pea protein and 30-50% v/v oil was determined. This pea protein concentration is more than what is needed to form a layer covering the interface. X-ray scattering revealed a thick, dense protein layer at the interface as well as hydrated protein dispersed in the continuous phase. Shear-thinning behavior was observed, and the high viscosity in combination with the thick protein layer at the interface creates a good stability against creaming and coalescence. Emulsions in a pH range from acidic to neutral were studied, and the overall stability was observed to be broadly similar independently of pH. Size measurements revealed polydisperse protein particles. The emulsion droplets are also very polydisperse. Apart from understanding pea protein-stabilized emulsions in particular, insights are gained about protein stabilization in general. Knowledge of the location and the role of the different components in the pea protein material suggests that properties such as viscosity and stability can be tailored for various applications, including food and nutraceutical products.

Oxidative Stress as a Target for Non-Pharmacological Intervention in MAFLD: Could There Be a Role for EVOO?

Oxidative stress plays a central role in most chronic liver diseases and, in particular, in metabolic dysfunction-associated fatty liver disease (MAFLD), the new definition of an old condition known as non-alcoholic fatty liver disease (NAFLD). The mechanisms leading to hepatocellular fat accumulation in genetically predisposed individuals who adopt a sedentary lifestyle and consume an obesogenic diet progress through mitochondrial and endoplasmic reticulum dysfunction, which amplifies reactive oxygen species (ROS) production, lipid peroxidation, malondialdehyde (MDA) formation, and influence the release of chronic inflammation and liver damage biomarkers, such as pro-inflammatory cytokines. This close pathogenetic link has been a key stimulus in the search for therapeutic approaches targeting oxidative stress to treat steatosis, and a number of clinical trials have been conducted to date on subjects with NAFLD using drugs as well as supplements or nutraceutical products. Vitamin E, Vitamin D, and Silybin are the most studied substances, but several non-pharmacological approaches have also been explored, especially lifestyle and diet modifications. Among the dietary approaches, the Mediterranean Diet (MD) seems to be the most reliable for affecting liver steatosis, probably with the added value of the presence of extra virgin olive oil (EVOO), a healthy food with a high content of monounsaturated fatty acids, especially oleic acid, and variable concentrations of phenols (oleocanthal) and phenolic alcohols, such as hydroxytyrosol (HT) and tyrosol (Tyr). In this review, we focus on non-pharmacological interventions in MAFLD treatment that target oxidative stress and, in particular, on the role of EVOO as one of the main antioxidant components of the MD.
