Phenolic and amino acid profiles along with organic acid, vitamin and mineral contents, major and minor sugars and enzyme activities of selected honey samples collected in North America were analyzed using different methods and potential markers of their botanical origin were identified. Among the 29 detected phenolic compounds, and some were found to be a good chemical markers to distinguish a genuine honey given its propolis origin. Quantitative data and principal component analysis showed that hesperidin, caffeic acid/isoferulic acid, and p-hydroxybenzoic acid/p-coumaric acid have the most positive relationship to the orange, alfalfa, and buckwheat honey, respectively, indicating their potential roles as chemical markers of these floral honeys. Free amino acid profiles were similar in all other honeys except buckwheat which not only had significantly higher branched-chain amino acids but was the only floral honey that contained L-norvaline that was identified for the first time. The enzyme activities and the major and rare sugar composition helped explain the presence of the various organic acids in the honeys. Compositional data of these bioactives and other nutrients will not only serve as database information for honey derived from North America but also provide insightful knowledge for the underlining potential health benefits.

Annona muricata Lin is known for its ethnomedicinal uses as food, decoctions, or infusions to address various conditions like skin infections, fever, diabetes, insomnia, malaria, hypertension, nervous disorders, diarrhea, and cancer. The study aimed to analyze the phytochemicals such as acetogenins, alkaloids, cyclopeptides, and flavonoids, present in A. muricata fruit, evaluate their pharmacokinetics, and understand binding dynamics with key molecular targets relevant to human well-being. Results indicated a mix of high and low gastrointestinal absorption (GIA) among A. muricata phytochemicals, with some demonstrating blood-brain barrier (BBB) permeability. Molecular target prediction highlighted frequent interactions with Programmed cell death protein 4 (PDCD4). Protein-protein interaction analysis revealed central connectivity of tyrosinase (TYR), Tyrosine 3-monooxygenase (TH), interleukin 2 (IL2), and others. Molecular docking results identified Luteolin 3´7-di-O-glucoside with the highest binding affinity for PDCD4 (-7.65 kcal.mol-1), followed by Annonaine (-7.294 kcal.mol-1); meanwhile, Dexamethasone (standard compound) exhibited a binding affinity of -6.682 kcal.mol-1. Molecular dynamic simulation indicated a stable binding energy ΔGbind (Total) for the Annonaine - PDCD4 complex (-11.240 kcal.mol-1) and Dexamethasone - PDCD4 complex (-18.909 kcal.mol-1). In conclusion, this study suggests potential anticancer properties of A. muricata based on modulation of PDCD4 protein, influencing the CDK/Akt/STAT3 pathway. Further in vivo investigations are necessary to validate these findings.

Sesamolin, one of the prominent lignans in sesame seeds, offers diverse physiological benefits. However, the longevity effects and mechanisms of sesamolin remain unclear. We hypothesized that sesamolin can exert the longevity effects in the Caenorhabditis (C.) elegans when prepared with the γ-cyclodextrin to form an inclusion complex (named γCD-SM). In this study, the γCD-SM was prepared, and the lifespan assays, health indexes, and loss-of-function assays in the C. elegans or mutants were conducted. The results demonstrated that the γCD-SM significantly extended the C. elegans’ lifespan and improved the health indexes, such as the pharyngeal pumping and body bends. The longevity effects of the γCD-SM were found to depend on the signaling of the SIR-2.1 and AAK-2. In conclusion, the γ-CD inclusion is a crucial step for assessing the sesamolin's longevity effects in the C. elegans. This study confirms that sesamolin exhibits the longevity effects, and its mechanism relies on the signaling of the SIR-2.1 and the AAK-2 proteins, suggesting its potential as a health-promoting ingredient.

Clove (Syzygium aromaticum L) is a precious spice that has been extensively used by many countries over the centuries to add flavor and for medicinal purposes. Because of its abundance of phytochemical compounds, clove has been shown to have positive benefits on human health. Hence, we investigated the anti-inflammatory activity of clove water extract (CWE) in LPS-stimulated RAW264.7 cells and mouse peritoneal. The results showed that CWE significantly inhibited the production of IL-6 and TNF-α in a dose-dependent manner, as well as the production of nitric oxide (NO), without any cytotoxic effects at less than 20 mg/mL, through down-regulating IL-6, TNF-α, and iNOS gene expression. Moreover, CWE impeded the MAPKs and inhibited the translocation of NF-kB from the cytosol to the nucleus. These results suggest that CWE possesses anti-inflammatory properties by inhibiting the MAPKs and NF-kB pathways.

This study aimed to assess the antibacterial and antioxidant properties of both crude polyphenol extract (CPE) and purified polyphenol extract (PPE) obtained from Fuji apple pomace. The antibacterial capacity of both extracts against Staphylococcus aureus was investigated by evaluating the inhibition zones, minimum bactericidal concentrations (MBC), growth curves and bacterial morphology of S. aureus treated with CPE or PPE, as well as the performance in simulated food systems. The antioxidant activity of CPE or PPE was assessed using the ABTS radical scavenging and ferric reducing antioxidant power (FRAP) assays. The results showed that PPE exhibited potent antibacterial activity against S. aureus, which was further confirmed by the bacterial morphology. It was revealed that PPE only exerted strong antibacterial effect in starch-based food system while CEP did not show such effect in all systems. The results of the ABTS and FRAP assays indicated that both PPE and CPE possess strong antioxidant activity, from which PPE showed much higher capacity than that of CPE. Therefore, PPE from Fuji apple pomace can be used as a novel antibacterial agent for food preservation and natural antioxidant for functional food and nutraceutical products.
本研究旨在评估从富士苹果渣中提取的粗多酚提取物（CPE）和纯化多酚提取物（PPE）的抗菌和抗氧化特性。通过评估用 CPE 或 PPE 处理的金黄色葡萄球菌的抑菌区、最低杀菌浓度 (MBC)、生长曲线和细菌形态，以及在模拟食品系统中的表现，研究了这两种提取物对金黄色葡萄球菌的抗菌能力。CPE 或 PPE 的抗氧化活性采用 ABTS 自由基清除和铁还原抗氧化能力（FRAP）测定法进行评估。结果表明，PPE 对金黄色葡萄球菌具有很强的抗菌活性，细菌形态也进一步证实了这一点。结果表明，PPE 只在以淀粉为基础的食品体系中具有较强的抗菌效果，而 CEP 在所有体系中均未显示出这种效果。ABTS 和 FRAP 检测结果表明，PPE 和 CPE 都具有很强的抗氧化活性，其中 PPE 的抗氧化能力远远高于 CPE。因此，富士苹果渣中的 PPE 可作为一种新型抗菌剂用于食品保鲜，也可作为天然抗氧化剂用于功能性食品和营养保健品。

Supplementing collagen is considered to contribute to delaying skin aging. In this work, we developed a novel combination for improving skin aging by stimulating the biosynthesis of collagen. By screening a library of Chinese herbal medicines (CHM), we found that Angelicae Dahuricae Radix (Baizhi), Lilii bulbus (Baihe), Glycyrrhizae radix et rhizoma (Gancao), and Jujubae fructus (Dazao) substantially increased the mRNA expression levels of type I collagen, suggesting their potential anti-skin-aging activity. To keep the structural integrity of collagen, prolyl 4-hydroxylase (P4H), a key enzyme in collagen synthesis, was recombinantly expressed in Escherichia coli. In addition, the transfersome with added P-4H was prepared to improve the transdermal absorption of combination. Vitamin C (VC), the substrate required for the activity of P4H, was also incorporated into the combination. Eventually, an optimal combination, consisting of Baizhi, Baihe, Gancao, P4H transfersome and VC, was obtained by a series of combination experiments. Based on traditional CHM and modern biological agents, we developed a novel combination against skin aging by promoting the synthesis of collagen. Collectively, the combination show the high potential of application to delay skin aging

Turmeric (Curcuma longa), widely used in Asia as a spice, preservative, and colorant, contains curcuminoids known for diverse pharmacological benefits, including antimicrobial properties. However, their hydrophobic nature hampers bioavailability. Addressing this, we hypothesized that Lactic Acid Bacteria (LAB) fermentation could enhance curcuminoid content and bioactivity. This study isolated LAB strains to ferment turmeric and investigated the phytochemical and pharmacological outcomes. Twelve LAB strains from various sources were tested for fermenting 3% turmeric in MRS broth. L. rhamnosus FN7 emerged as a robust strain, tolerating turmeric's antibacterial properties and increasing curcuminoid content and anti-inflammatory effects. Fermented turmeric exhibited higher phenolic and flavonoid contents and improved radical scavenging activity than its non-fermented counterpart. Additionally, L. rhamnosus FN7 survived under simulated gastrointestinal conditions, indicating probiotic potential. Our findings suggest that L. rhamnosus FN7 fermentation significantly boosts turmeric's biochemical attributes, positioning it as a promising functional food.

Coreopsis tinctoria Nutt (C. tinctoria) or a common name ‘Snow chrysanthemum’ because of its growing condition at high altitude，is one of the popular medicinal-food plants, mainly grows in the northwest area of China. Because of its rich nutrients, particularly polyphenols (majorly flavonoids), and volatile oils among others, C. tinctoria has become a research hotspot in recent years. In addition, the flavonoids of C. tinctoria, especially the flavanomarein, marein, okanin and other bioactive phytochemicals, have effective biological activity. They possess good antioxidant and anti-inflammatory effects, also have significant effects on lowering blood pressure, hypoglycemia and reducing levels of triglycerides and cholesterol. However, at present, studies on the bioactivity of C. tinctoria are mainly focused on crude extracts or total flavonoids. The study of monomer components is largely limited to the isolation and purification process, which is difficult for a systematic study because of the chemical-physical nature of marein, flavanomarein and other compounds in C. tinctoria. Therefore, to have an updated isolation of C. tinctoria bioactive components, this paper reviewed the current research status of the separation and purification methods of flavonoids from C. tinctoria, by analyzing and comparing the technical characteristics of these methods, and providing prospects on the development and application of the separation and purification methods of C. tinctoria.
拟南芥（Coreopsis tinctoria Nutt，又名 "雪菊"，因其生长在高海拔地区而得名）是一种常用的药食两用植物，主要生长在我国西北地区。由于其营养丰富，尤其是多酚类（主要是黄酮类）和挥发油等，近年来，杭白菊已成为研究热点。此外，洋二仙草的黄酮类化合物，尤其是黄烷马利素、马利素、黄烷宁和其他生物活性植物化学物质，具有有效的生物活性。它们具有良好的抗氧化和抗炎作用，对降血压、降血糖、降低甘油三酯和胆固醇水平也有显著效果。然而，目前对 C. tinctoria 生物活性的研究主要集中在粗提取物或总黄酮上。对单体成分的研究主要局限于分离和纯化过程，由于马钱子苷、黄烷马钱子苷和马钱子中其他化合物的化学物理特性，很难进行系统的研究。因此，为了更新马钱子生物活性成分的分离方法，本文综述了马钱子黄酮类化合物分离纯化方法的研究现状，分析比较了这些方法的技术特点，并对马钱子黄酮类化合物分离纯化方法的发展和应用进行了展望。

Because of its rich nutrients, particularly polyphenols (majorly flavonoids), and volatile oils among others, C. tinctoria has become a research hotspot in recent years. In addition, the flavonoids of C. tinctoria, especially the flavanomarein, marein, okanin and other bioactive phytochemicals, have effective biological activity. They possess good antioxidant and anti-inflammatory effects, also have significant effects on lowering blood pressure, hypoglycemia and reducing levels of triglycerides and cholesterol. However, at present, studies on the bioactivity of C. tinctoria are mainly focused on crude extracts or total flavonoids.
