However, their stability is compromised by factors such as pH, temperature, and light exposure. Previous research demonstrated improved pH stability in black grape ANCs through cobalt ion (Co+2) complexation. This study investigates the effects of Co+2 complexation on the thermal and light stability of black grape ANCs extracted from pomace. These ANCs were purified, complexed with Co+2 (ANC-Co+2), and diluted in a pH 4.5 buffer solution. Purified ANCs were also diluted in a pH 3.5 buffer solution. Both ANCs and ANC-Co+2 were heated to 40°C, 60°C, and 80°C for 7 h to assess thermal stability. To evaluate light stability, ANCs and ANC-Co+2 were stored separately under ultraviolet (UV) light and daylight for one week. Thermal stability results revealed that complexation could significantly (P≤0.05) extend ANC half-life by more than threefold and reduce temperature sensitivity by approximately 50%. Thermal degradation of ANCs was endothermic, nonspontaneous, and more structured in the transition state, as indicated by thermodynamic parameters (activation enthalpy (ΔH)>0, free energy of inactivation (ΔG)>0, and activation entropy (ΔS)<0). Light stability tests revealed that complexation significantly (P≤0.05) extended ANC half-life by over tenfold and twentyfold under UV and daylight exposure, respectively. Therefore, Co+2 complexation represents an effective technique to enhance the thermal and light stability of grape ANCs, making them more suitable for use as food colorants.","PeriodicalId":20424,"journal":{"name":"Preventive Nutrition and Food Science","volume":"29 4","pages":"495-503"},"PeriodicalIF":1.6,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11699574/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aimed to determine the antioxidant contents, scavenging activity, and toxicity of aqueous extracts of common Omani plants. The total phenolic content (TPC), total flavonoid content (TFC), scavenging activity against hydrogen peroxide (H2O2), and brine shrimp lethality of the aqueous extracts of commonly used Omani ethnobotanical plants were evaluated. The samples exhibited a wide range of the investigated parameters. TPC ranged from 0.52 to 65.14 mg gallic acid equivalent/g dry solid, whereas TFC ranged from 0.07 to 37.14 mg catechin equivalent/g dry solid. Moreover, the scavenging activity ranged from 6.9% to 91.9%. Among 18 plant species that were examined, Pteropyrum scoparium, Moringa peregrina, Dodonaea viscosa, Rhus aucheri, Acridocarpus orientalis, and Prosopis cineraria showed high values in almost all parameters. At exposure levels of 1 to 1,000 μg/mL, the lethality test using four plants with the highest TPC values and scavenging activity (M. peregrina, P. scoparium, R. aucheri, and P. cineraria) revealed that they may be safe for consumption as food or medicine. In general, the study demonstrated that some Omani plant species may be potential sources of phenolic compounds and flavonoids. Thus, these plant species should be propagated to be used in the food and nutraceutical industries. Moreover, they can be consumed to combat chronic oxidative stress-mediated diseases.","PeriodicalId":20424,"journal":{"name":"Preventive Nutrition and Food Science","volume":"29 4","pages":"485-494"},"PeriodicalIF":1.6,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11699577/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142931370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this research, therefore, was to evaluate the content of phytochemical compounds, levels of toxicity, and antibacterial activity of the extracts, fractions, and essential oil derived from C. lutea leaves. The plant material was subjected to extraction by maceration, Soxhlet extraction, and steam distillation, and fractions of hexane, dichloromethane, ethyl acetate, and a residual ethanol-water fraction were obtained. Preliminary phytochemical screening was performed using standard procedures with staining reagents. Estimation of the toxicity was carried out using the Caenorhabditis elegans biological model. Antibacterial activity was determined by broth microdilution against Staphylococcus aureus and Escherichia coli. The results showed that the characteristic metabolites were flavonoids, triterpenes, and tannins. At the concentrations tested, the extracts, fractions, and essential oil showed minimal toxicity levels. In terms of antibacterial activity, E. coli showed no susceptibility; meanwhile, the dichloromethane fraction had high antibacterial activity against S. aureus, with a growth inhibition rate of 81.2%. The results suggested that the of dichloromethane fraction of C. lutea has antibacterial activity against S. aureus, suggesting its potential as a possible candidate as a natural antibacterial agent in the food industry. This alternative could offer a safer and more sustainable solution compared to the conventional synthetic preservatives.","PeriodicalId":20424,"journal":{"name":"Preventive Nutrition and Food Science","volume":"29 4","pages":"522-532"},"PeriodicalIF":1.6,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11699569/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142931369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DJ contains flavonoid glycosides, bioactive compounds that have been found in various plants and have promising pharmacological effects. A representative flavonol glycoside is quercitrin, a standard compound. Notwithstanding, its adoption by the food industry, it is necessary to standardize the quantification of quercitrin in DJ. Thus, an analytical method needs to be developed and validated to quantify quercitrin accurately. In this study, we established a high-performance liquid chromatography (HPLC) method for quantifying quercitrin in DJ extracts (DJEs); then, we validated the method, to ensure its accuracy and reliability. Our results demonstrated that the HPLC method effectively detecteds quercitrin in DJE samples, consistently reporting retention times and peak spectra similar to those in the standard solutions. The linearity assessment revealed a linear response within the concentration range of 2.5 to 15.0 μg/mL, which was supported by strong correlation coefficients (R2>0.9997). Accuracy assessment via recovery studies produced satisfactory results (89.02%－99.30%), with a relative standard deviation (RSD) within acceptable limits (0.50%－5.95%). Precision analysis confirmed the repeatability and reproducibility of the method, with RSD values within the Association of Official Agricultural Chemists (AOAC) standard criteria (≤8%). Overall, our study provides a validated HPLC method for quercitrin quantification in DJEs, facilitating its standardization and ensuring the accuracy of the analysis. This method is potentially valuable for quality control and further research on the health-promoting properties of DJ.","PeriodicalId":20424,"journal":{"name":"Preventive Nutrition and Food Science","volume":"29 4","pages":"504-511"},"PeriodicalIF":1.6,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11699575/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite substantial evidence supporting its anti-inflammatory properties, the biological activities of C. fenestratum are unclear. This study aimed to elucidate anticolitis mechanisms of C. fenestratum alkaloids (CFAs) using an integrative approach of network pharmacology and molecular docking analyses. Key active alkaloids and core target genes were identified through pharmacological and protein-protein interaction networks. The core targets were enriched in the Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathways to determine the functional properties of active CFA. Finally, the binding affinity of the key compounds with the core targets was determined using molecular docking. The results showed that 11 active CFAs interactively interfered with 10 hub genes related to ulcerative colitis, including prostaglandin-endoperoxide synthase 2 (PTGS2), selectin E (SELE), kinase insert domain receptor (KDR), fms-related receptor tyrosine kinase 1 (FLT1), intracellular adhesion molecule 1 (ICAM1), C-X-C motif chemokine receptor 4 (CXCR4), hypoxia-inducible factor-1 (HIF1A), matrix metalloproteinase (MMP)-2, MMP3, and MMP9, which were functionally involved in the immunological response, tumor necrosis factor signaling pathway, and interleukin-17 signaling pathway. The molecular docking results indicated that CFA compounds had a strong binding affinity for the hub genes.

However, thickened OJ displayed a different curve pattern comprising five regimes because of the presence of small pulp and gel particles. As the thickener concentration was increased, the maximum friction coefficient (μ) values of thickened BW, SD, and OJ decreased, whereas that of thickened WM increased because of the depletion flocculation of emulsion particles. The maximum μ values of thickened beverages, except for thickened WM, were positively correlated with n and tan δ values with increasing thickener concentration.

However, few studies have investigated the effects of CE in prehypertensive individuals. Here, we conducted a randomized crossover clinical trial on prehypertensive offspring of hypertensive parents to evaluate the effects of preworkout CE consumption (CEC) on post-exercise hypotension (PEH) and cardiac autonomic and vascular responses. Ten prehypertensive males participated in three randomly ordered sessions: a resting control (REST) condition and two exercise conditions involving CEC and an exercise control (CON). The participants in the CEC condition consumed CE daily for seven days prior to the experimental sessions. Measurements were taken before and after each intervention. The results showed that the CEC condition resulted in significantly lower systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) at night compared with the CON and REST conditions (P<0.05 and P<0.01, respectively). This reduction in SBP and MAP in the CEC condition was observed as early as 10 min and persisted for up to 12 h after a single exercise session. Only the CEC condition showed significantly higher root mean square of successive differences at night (P<0.05) and across a 24-h period (P<0.05). Moreover, we observed a significantly lower brachial-ankle pulse wave velocity 30 min post-exercise (P<0.05). These findings support the efficacy of CE in promoting PEH, particularly with greater reductions in SBP, DBP, and MAP at night, while also enhancing post-exercise vagal activity and reducing vascular stiffness. Thus, CEC may be an effective strategy for preventing hypertension.","PeriodicalId":20424,"journal":{"name":"Preventive Nutrition and Food Science","volume":"29 4","pages":"394-404"},"PeriodicalIF":1.6,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11699581/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142931559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
