Abstract
BACKGROUND Saccharomyces cerevisiae plays a pivotal role in various industrial processes, including bioethanol production and alcoholic beverage fermentation. However, during these fermentations, yeasts are subjected to various environmental stresses, such as ethanol stress, which hinder cell growth and ethanol production. Genetic manipulations and the addition of natural ingredients rich in antioxidants to the culture have been shown to overcome this. Here, we investigated the potential of persimmon tannins, known for their antioxidative properties, to enhance the ethanol stress tolerance of yeast. RESULTS Assessment of the effects of 6.25 mg mL-1 persimmon tannins after 48 h incubation revealed cell viability to be increased by 8.9- and 6.5-fold compared to the control treatment with and without 12.5% ethanol, respectively. Furthermore, persimmon tannins reduced ethanol-induced oxidative stress, including the production of cellular reactive oxygen species and acceleration of lipid peroxidation. However, persimmon tannins could hardly overcome ethanol-induced cell membrane damage. CONCLUSION The findings herein indicate the potential of persimmon tannin as a protective agent for increasing yeast tolerance to ethanol stress by restricting oxidative damage but not membrane damage. Overall, this study unveils the implications of persimmon tannins for industries relying on yeast. © 2024 The Authors.

Abstract
More and more evidence has supported the interaction between circadian rhythms and intestinal microbes, which provides new insights into how dietary nutrition can improve host health. Our research showed that Ficus pandurata Hance var. angustifolia Cheng flavonoids (FCF) ameliorated the pathological damage of colon and abnormal intestinal microflora structure in mice with circadian clock disorder and improved their exploration and memory behaviors. Mechanism studies have shown that FCF is involved in regulating metabolic pathways and related metabolites, regulating the expression of related tight junction proteins in the colon and the levels of Aβ and inflammatory factors in the hippocampus. Further analysis found that these metabolites showed a certain correlation with intestinal flora and played a certain role in alleviating intestinal physiological damage and cognitive decline.

Abstract
Nonalcoholic fatty liver disease (NAFLD), the most common chronic liver disease, is a multifactorial disease resulting from the interaction between environment, genetic background, and metabolic stress. Most treatments for NAFLD include dietary intervention and exercise show limited efficacy due to the complex mechanisms involved in NAFLD. Meanwhile, drug therapy is accompanied by serious side effects. The development of high-efficiency natural supplements is a sustainable strategy for the prevention and treatment of NAFLD. As the second most consumed beverage, tea has health benefits that have been widely recognized. Nevertheless, the intervention of tea active compounds in NAFLD has received limited attention. Tea contains abundant bioactive compounds with potential effects on NAFLD, such as catechins, flavonoids, theanine, tea pigments, and tea polysaccharides. We reviewed the intrinsic and environmental factors and pathogenic mechanisms that affect the occurrence and development of NAFLD, and summarized the influences of exercise, drugs, diet, and tea drinking on NAFLD. On this basis, we further analyzed the potential effects and molecular regulatory mechanisms of tea active compounds on NAFLD and proposed future development directions. This review hopes to provide novel insights into the development and application of tea active compounds in the prevention and treatment of NAFLD.

Abstract
Introduction: Oolong tea, a functional food, has numerous therapeutic benefits owing to the presence of bioactive polyphenols, theasinensins (TS) and catechins. The present study aimed to evaluate the influence of systemic administration of oolong tea as an adjunct to nonsurgical periodontal therapy (NSPT) in the management of chronic periodontitis (CP).Methods: A total of 60 subjects with mild to moderate CP were randomly divided into two groups of tests (n = 30) and the controls (n = 30). They underwent NSPT with adjunctive oolong tea supplementation in the test group only. At baseline, 1, and 3 months, their gingival index (GI), plaque index (PI), probing pocket depth (PPD), clinical attachment loss (CAL), percentage of sites with bleeding on probing (BOP), and lobene stain index (LSI) were recorded. Furthermore, the levels of glutathione peroxidase (GPx), total antioxidants (TAO), and malondialdehyde (MDA) were also estimated in gingival crevicular fluid (GCF), saliva and serum. Additionally, colony-forming units (CFUs) of selective supra and subgingival plaque bacteria were estimated in the plaque samples.Results: In both groups, at 1 month, the GI, PI, BOP, GPx, and TAO levels were improved with a reduction in the levels of MDA and CFU’s and no staining of teeth (P < 0.05). The results were maintained in the test group at 3-month recall visit.Conclusion: Adjunctive administration of oolong tea with NSPT reduced the local and systemic oxidative burden and rapidly resolved the inflammation in CP. This would be specifically beneficial in CP subjects with systemic conditions.

Abstract
Enterococcus faecalis (E. faecalis) is a resident bacterium in the host. The increase of internal stress like low pH may affect the biological effects of E. faecalis. The prebiotic-like function of tea polyphenols can enhance the beneficial effects of its tolerance to environmental stress. In this study, RNA-sequence analysis was used to explore the protective effect of green tea polyphenols (GTP) on E. faecalis under low pH stress. A total of 28 genes were found to be responsive to GTP under low pH stress, including 16 up-regulated and 12 down-regulated. GTP intervention can partly relieve some undesired negative influences, such as the down-regulation of the base excision repair gene and amino acid transport and metabolism gene. The significantly changes were associated with selenocompound metabolism and aminoacyl-tRNA biosynthesis after the intervention of GTP. The present study provided new insights into the growth and continuous adaptation of E. faecalis under stress.

Abstract
The paracetamol-induced injuries of liver and kidneys in animals are mostly used to screen out the hepato and nephroprotective effect of extract or other therapeutic agents. In the present study total phenolic and flavonoid contents, in vitro antioxidant, and in vivo hepato/nephroprotective (on paracetamol-induced intoxication in experimental rabbits) potentials of the Daphne mucronata leaves methanolic extract were determined. For the identification of possible phytochemicals, HPLC (high performance liquid chromatography) analysis was carried out and a total of eight phenolic compounds; malic acid, gallic acid, chlorogenic acid, epigallocatechin gallate, quercetin, morin, ellagic acid, and rutin were identified. D. mucronata extract at doses of 250 and 500 mg/kg body weight were given for eight days to paracetamol intoxicated rabbits and the observed results were compared with standard Silymarin. The level of liver enzymes like aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, serum triglyceride, serum cholesterol, serum bilirubin, and kidneys biomarkers like serum urea, uric acid, and creatinine, as well as lipid peroxidation malondialdehyde contents were increased while the antioxidant enzymes like reduced glutathione and total antioxidant capacity were decreased. Furthermore, histopathological analysis of the liver and kidney tissues of control and treated groups also confirmed the hepatoprotective and nephroprotective effect of the D. mucronata which was most probably due to its high antioxidant phenolic and flavonoid phytoconstituents.

Abstract
Tea polyphenols (TP) are the most bioactive components in tea extracts. It has been reported that TP can regulate the composition and the function of the intestinal flora. Meanwhile, intestinal microorganisms improve the bioavailability of TP, and the corresponding metabolites of TP can regulate intestinal micro-ecology and promote human health more effectively. The dysfunction of the microbiota-gut-brain axis is the main pathological basis of depression, and its abnormality may be the direct cause and potential influencing factor of psychiatric disorders. The interrelationship between TP and intestinal microorganisms is discussed in this review, which will enable us to better evaluate the potential preventive effects of TP on psychiatric disorders by modulating host intestinal microorganisms.

Abstract
Alcoholic liver disease (ALD) is one type of liver disease, causing a global healthcare problem and mortality. The liver undergoes tissue damage by chronic alcohol consumption because it is the main site for metabolism of ethanol. Chronic alcohol exposure progresses from alcoholic fatty liver (AFL) to alcoholic steatohepatitis (ASH), which further lead to fibrosis, cirrhosis, and even hepatocellular cancer. Therapeutic interventions to combat ALD are very limited such as use of corticosteroids. However, these therapeutic drugs are not effective for long-term usage. Therefore, additional effective and safe therapies to cope with ALD are urgently needed. Previous studies confirmed that edible food plants and their bioactive compounds exert a protective effect against ALD. In this review article, we summarized the hepatoprotective potential of edible food plants and their bioactive compounds. The underlying mechanism for the prevention of ALD by edible food plants was as follows: anti-oxidation, anti-inflammation, lipid regulation, inhibition of apoptosis, gut microbiota composition modulation, and anti-fibrosis.

Abstract
Polyphenols are natural substances that have been shown to provide various health benefits. Antioxidant, anti-inflammatory, and anti-carcinogenic effects have been described. At the same time, they inhibit the actions of bacteria, viruses, and fungi. Thus, studies have also examined their effects within the oral cavity. This review provides an overview on the different polyphenols, and their structure and interactions with the tooth surface and the pellicle. In particular, the effects of various tea polyphenols on bioadhesion and erosion have been reviewed. The current research confirms that polyphenols can reduce the growth of cariogenic bacteria. Furthermore, they can decrease the adherence of bacteria to the tooth surface and improve the erosion-protective properties of the acquired enamel pellicle. Tea polyphenols, especially, have the potential to contribute to an oral health-related diet. However, in vitro studies have mainly been conducted. In situ studies and clinical studies need to be extended and supplemented in order to significantly contribute to additive prevention measures in caries prophylaxis.

Abstract
Abstract
Background
Epigallocatechin gallate (EGCG) acts as an antioxidant by preventing oxidative stress. The effect of EGCG on aluminum-induced testicular injury is not clear. Hence, the present study is planned to investigate the effect of EGCG on aluminum chloride (AlCl3)-induced changes in behavior, biochemical parameters, and spermatogenesis in male Sprague-Dawley rats. The rats were divided into six groups with six animals each. All the animals were administered with respective assigned treatment once daily for 28 days. The animals in groups I to VI were administered with drug vehicle, AlCl3, vitamin C, EGCG, vitamin C, and EGCG, respectively. The animals in groups V and VI were additionally challenged with AlCl3 (10 mg/kg) immediately after vitamin C and EGCG administration, respectively. Changes in behavior were measured on day 1, 14 and 28. At the end of the study, the blood sample was collected from all the animals, and the serum was separated and used for biochemical analysis. Later, the rats were subjected to bilateral orchiectomy; sperm was collected from the cauda epididymis for microscopic examination. Then, the animals were sacrificed, and the organs such as the brain, lungs, heart, liver, kidney, spleen, and testis were collected for organ weight analysis.
Results
The animal administered with AlCl3 showed a reduction in locomotor activity, grip strength, and escape latency time whereas vitamin C prevented the effect of AlCl3. But, EGCG did not show any significant changes in AlCl3-induced behavioral and biochemical changes. At the end of the study, vitamin C prevented AlCl3-induced behavioral and biochemical changes. The group of animals administered with AlCl3 showed a reduction in the number of spermatozoa whereas AlCl3 + vitamin C and AlCl3 + EGCG did not show any significant changes in the number of spermatozoa when compared to the control group.
Conclusion
EGCG prevented AlCl3-induced reduction in epididymal sperm count of male rats and did not show any significant effect on AlCl3-induced changes in behavior and biochemical parameters, whereas vitamin C had an ameliorative effect on AlCl3-induced changes in behavior, biochemical parameter, and spermatogenesis.

Abstract
Choline as a quaternary amine nutrient is metabolized to trimethylamine by gut microbiota and subsequently oxidized to circulating trimethylamine-N-oxide (TMAO), a gut-derived metabolite associated with liver toxicity and cardiovascular disease. The study was to probe the possible vasoprotective and hepatoprotective effects of total saponins of Gynostemma pentaphyllum (TSGP) in 3% high-choline water-feeding mice. The purified TSGP was obtained with content of 83.0% saponins, and its antioxidant activities were evaluated in vitro. Furthermore, the mice fed with high choline for 8 weeks significantly expressed vascular endothelial dysfunction and liver oxidative stress (p < 0.01 vs. Normal). Administration of TSGP at 400 and 800 mg/kg·body weight (b.w.) significantly lowered the serum total cholesterol (TC), triglyceride (TG), low density lipoprotein-cholesterol (LDL-C), endothelin-1 (ET-1) and thromboxane A2 (TXA2) levels, as well as hepatic malondialdehyde (MDA) formation, but effectively elevated the serum nitric oxide (NO), endothelial nitric oxide synthase (eNOS) and prostaglandin I2 (PGI2) levels, as well as alanine aminotransferase (ALT), aspartate aminotransferase (AST), T-superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities in high choline-fed mice. Hematoxylin-eosin (H&E) and oil red O staining also suggested that TSGP could exert the significant protection against endothelial dysfunction and liver injury in high choline-treated mice. These findings suggest that TSGP is of the saponins-enriched extract, and is a good candidate of dietary supplement and therapeutic application in vascular and hepatic oxidative injury.

Abstract
Flavonoids from Sedum aizoon L. (FSAL) possess prominent antibacterial activity against Shewanella putrefaciens isolated from sea food. In the current study, the involved molecular mechanisms were investigated using transcriptome analyses combined with bioinformatics analysis in vitro for the first time. Results showed that treatment of FSAL (1.0 MIC) damaged the permeability and integrity of cell membrane and induced 721 differentially expressed genes (DEGs) in tested bacteria at transcriptional levels, including 107 DEGs were up-regulated and 614 DEGs were down-regulated. In addition, the RNA-Seq analysis revealed that the majority of DEGs mainly involved in pathways of lipopolysaccharide biosynthesis, glycerophospholipid metabolism, biosynthesis of amino acids, purine metabolism, ABC transporters and response to stimulus. In summary, the integrated results indicated that the intervention of FSAL induced destruction of cell wall and membrane, disorder of the metabolic process and redox balance, and damage of nucleic acids in S. putrefaciens, at last resulted in the death of cells. This study provided new insights into the anti- S. putrefaciens molecular mechanism underlying the treatment of FSAL, which may be served as the basis guide for identifying potential antimicrobial targets and application of FSAL in food safety.

Abstract
Baiyacha (BYC) is a kind of wild tea plant growing and utilizing in the remote mountain area of Fujian province, Southeastern China. However, scientific studies on this plant remain limited. Our results showed that BYC exhibits the typical morphological characteristics of Camellia gymnogyna Chang, a closely related species of C. sinensis (L.) O. Kuntze, which was not found in Fujian before. Chemical profiling revealed that parts of BYC plants are rich in purine alkaloids and catechins, especially featuring high levels of theacrine and 3″-methyl-epigallocatechin gallate (EGCG3″Me), chemical compounds with multiple biological activities that are rarely observed in regular tea plants. The contents of EGCG3″Me and theacrine in BYC both increased with the leaf maturity of tea shoots, whereas the caffeine content decreased significantly. The obtained results provide abundant information about the morphology and chemical compounds of BYC and may be used for tea production, breeding, and scientific research in the future.

Abstract
Microbiome has been revealed as a key element involved in maintaining the circadian rhythms. Oolong tea polyphenols (OTP) has been shown to have potential prebiotic activity. Therefore, this study focused on the regulation mechanisms of OTP on host circadian rhythms. After 8 weeks of OTP administration, a large expansion in the relative abundance of Bacteroidetes with a decrease in Firmicutes was observed, which reflected the positive modulatory effect of OTP on gut flora. In addition, Kyoto Encyclopedia of Genes and Genomes pathways of ATP-binding cassette transporters, two-component system, and the biosynthesis of amino acids enriched the most differentially expressed genes after OTP treatment. Of the differentially expressed proteins identified, most were related to metabolism, genetic information processing, and environmental information processing. It underscores the ability of OTP to regulate circadian rhythm by enhancing beneficial intestinal microbiota and affecting metabolic pathways, contributing to the improvement of host microecology.

Abstract
Tea, as one of the most popular beverages with various bioactivities, is commonly produced from the fresh leaves of two widely cultivated tea plants, Camellia sinensis and C. sinensis var. assamica. Both plants belong to the genus Camellia section Thea, which was considered to have 12 species and 6 varieties according to Min's taxonomic system. Most species, except the cultivated species, are known as wild tea plants and have been exploited and utilized to produce tea by the local people of its growing areas. Thus far, six species and varieties have been phytochemically studied, leading to the identification of 398 compounds, including hydrolyzable tannins, flavan-3-ols, flavonoids, terpenoids, alkaloids, and other phenolic and related compounds. Various beneficial health effects were reported for tea and its components, involving antioxidant, antitumor, antimutagenic, antidiabetic, hypolipidemic, anti-inflammatory, antimicrobial, antiviral, antifungal, neuroprotective, hepatoprotective, etc. In this review, the geographical distribution of tea plants and the chemical constituents (1-398) reported from the genus Camellia section Thea and some tea products (green, black, oolong, and pu-erh tea) that have ever been studied between 1970 and 2018 have been summarized, taking species as the main hint, and the main biological activities are also discussed.

Abstract
Despite the remarkable bioactivity, the potential of EGCG3''Me to be fully utilized has not yet been completely elucidated due to its low absorption. It has been reported that phospholipids can act as agents to improve the absorption of antioxidants. Therefore, EGCG3''Me phospholipid complex (EPC) was utilized in this study to investigate its activity on gut flora of an obesity mouse model. After the administration of the complex for 8 weeks, the relative abundance of Bacteroidetes was significantly increased (p < 0.05); meanwhile, the relative abundance of Firmicutes was decreased, suggesting the potential anti-obesity effect of the complex. Furthermore, the expression of Muc2 and Reg3g were directly upregulated by EPC intervention. PRACTICAL APPLICATIONS: Although EGCG3''Me has shown excellent biological benefits, the presence of multiple hydroxyl groups and high polar properties hindered its application. This study indicated the potential of phospholipids in promoting the bioavailability of EGCG3''Me and might contribute to the production of functional food with better tea catechins absorption.

Abstract
Saccharomyces cerevisiae has been widely used to produce alcoholic beverages and bio-fuels; however, its performance is remarkably compromised by the increased ethanol concentration during the fermentation process. In this study, RNA-sequence analysis was used to investigate the protective effect of green tea polyphenols (GTP) on S. cerevisiae cells from ethanol-induced damage. GO and KEGG analysis showed that to deal with the stress of ethanol, large amounts of genes related to cell wall, cell membrane, basic metabolism and redox regulation were significantly differentially expressed (P < 0.05), while these undesired changes could be partly relieved by administration of GTP, suggesting its potential to enhance the ethanol tolerance of S. cerevisiae. The present study provided a global view of the transcriptomic changes of S. cerevisiae in response to the accumulation of ethanol and the treatment of GTP, which might deepen our understanding about S. cerevisiae and the fermentation process, and thus benefit the development of the bioethanol production industry.

Abstract
This study aimed to compare the beneficial effect of catechin-enriched green tea and oolong tea on mildly hypercholesterolemic subjects. Sixty mildly hypercholesterolemic subjects (180-220 mg dL-1) were enrolled and divided into three groups as catechin-enriched green tea (CEGT), catechin-enriched oolong tea (CEOT) or placebo. The subjects were instructed to drink 2 × 300 mL of CEGT (780.6 mg of catechin), CEOT (640.4 mg of catechin) or placebo beverage for 12 weeks. Drinking CEGT and CEOT significantly decreased (p < 0.05) the body weight, fat, and BMI, lipid peroxidation as well as lipid profile (TC, LDL-c, HDL-c, and TG). Also, intervention with CEGT and CEOT significantly improved (p < 0.05) the oxidative indices (TEAC and GSH) and antioxidant enzymes (SOD, CAT, GPx, and GR). Moreover, ultrasound examination endorsed the hepatoprotective activity of CEGT and CEOT by reverting mild fatty liver to the normal hepatic condition because of antioxidant and hypolipidemic activities. To summarize, both CEGT and CEOT showed similar antioxidant and hepatoprotective activities. However, CEOT displayed superior lipid-lowering activity compared to CEGT or placebo, and hence it could be used to amend the wellness condition of mildly hypercholesterolemic subjects.

Abstract
The mechanistic systems in the body through which tea causes weight loss are complex and multi-dimensional. Additionally, the bioactive components in tea such as catechins, caffeine, and products of tea polyphenol oxidation vary greatly from one major tea type to the next. Green tea has been the primary subject of consideration for investigation into the preventative health effects of tea because it contains the highest levels of phenolic compounds and retains the highest antioxidant capabilities of any major tea type. However, recent research suggests decreasing body fat accumulation has little to do with antioxidant activity and more to do with enzyme inhibition, and gut microbiota interactions. This paper reviews several different tea polyphenol-induced weight-loss mechanisms, and purposes a way in which these mechanisms may be interrelated. Our original 'short-chain fatty acid (SCFA) hypothesis' suggests that the weight-loss efficacy of a given tea is determined by a combination of carbohydrate digestive enzyme inhibition and subsequent reactions of undigested carbohydrates with gut microbiota. These reactions among residual carbohydrates, tea polyphenols, and gut microbiota within the colon produce short-chain fatty acids, which enhance lipid metabolism through AMP-activated protein kinase (AMPK) activation. Some evidence suggests the mechanisms involved in SCFA generation may be triggered more strongly by teas that have undergone fermentation (black, oolong, and dark) than by non-fermented (green) teas. We discussed the mechanistic differences among fermented and non-fermented teas in terms of enzyme inhibition, interactions with gut microbiota, SCFA generation, and lipid metabolism. The inconsistent results and possible causes behind them are also discussed.

Abstract
Obesity is a serious health problem in adults and children worldwide. However, the basic strategies for the management of obesity (diet, exercise, drugs and surgery) have limitations and side effects. Therefore, many researchers have sought to identify bioactive components in food. Tea and coffee are the most frequently consumed beverages in the whole world. Their health benefits have been studied for decades, especially those of green tea. The anti-obesity effect of tea and coffee has been studied for at least ten years. The results have shown decreased lipid accumulation in cells via the regulation of the cell cycle during adipogenesis, changes in transcription factors and lipogenesis-related proteins in the adipose tissue of animal models, and decreased body weight and visceral fat in humans. Tea and coffee also influence the gut microbiota in obese animals and humans. Although the anti-obesity mechanism of tea and coffee still needs further clarification, they may have potential as a new strategy to prevent or treat obesity.

Abstract
In this study, the role of phospholipids in transepithelial transport and the impact on the antioxidant activity of purple sweet potato anthocyanins (PSPAs) was evaluated. PSPAs were purified by column chromatography, and then PSPAs-phospholipids complex (PSPAs-PC) was prepared. In antioxidant assay in vitro, PSPAs-PC exhibited potential antioxidant activity; meanwhile, it exhibited relatively higher stability in mimic gastrointestinal digestion conditions. The inhibitory effect of PSPAs-PC on the oxidation of soybean oil was significantly higher after 15 days storage. The presence of phospholipids increased the transepithelial transport of PSPAs; its apparent permeability coefficient (Papp) was higher, while its efflux ratio was lower than PSPAs. Based on the above results, it clearly displays the potential of phospholipids in the promotion of intestinal transport of PSPAs, and further studies are needed to explore the in-depth mechanism of the bioavailability promotion effect of phospholipids.

Abstract
The variations in the contents of tea catechins and free amino acids in relation to the quality of Fenghuang Oolong teas (FOT) were determined. It demonstrated that in FOT, which were grown at a high altitude, the contents of methylated estered tea catechins were relatively higher. By human flora-associated (HFA) mice model, the effect of FOT on high-fat diet-induced obesity was investigated by high-throughput sequencing. The shifts in relative abundance of the dominant taxa at the phylum, family and genus levels showed their dramatically effects. A large increase in Bacteroidetes with decrease of Firmicutes was observed after the administration of FOT for 8 weeks. Together, these results suggest that FOT are rich in tea catechins, especially O-methylated tea catechin derivatives, which may be affected by the unique growth environment, and FOT may have prebiotic-like activity and can be used as functional food components in manipulating intestinal microbiota.

Abstract
OBJECTIVES Previous studies found that tea consumption was related to a reduction in the risks of some chronic diseases, but limited data are available on bone health. This study aimed to examine the associations of tea consumption with hip bone strength in Chinese women. DESIGN Cross-sectional study. SETTING The participants were from the ongoing Guangzhou Nutrition and Health Study. This was a cohort study started in 2008. The examination data conducted between June 2010 and December 2013 were used. PARTICIPANTS A total of 1,495 Chinese women aged more than 40 years were included. MEASUREMENTS Tea consumption, socio-demographic information and lifestyle habits were collected by a face-to-face questionnaire. Hip bone mineral density (BMD) and geometric parameters, i.e. cross-sectional area (CSA), section modulus (Z) and buckling ratio (BR), were generated by dual-energy X-ray absorptiometry. The associations of tea consumption with bone phenotypes were detected by analysis of covariance and multiple linear regression models after adjusting for age, body mass index, years since menopause, physical activity, dietary-protein intake, dietary-calcium intake, calcium tablet intake, drinking status and smoking status. RESULTS Tea drinkers (n = 732) had approximately 1.9% higher BMD (p < 0.05) and 3.6% lower BR (p < 0.05) than non-tea drinkers (n = 763). The dose-response relationships of BMD, BR or CSA with total tea consumption were identified (p-trend < 0.05). Tea drinking was found to be a significant and independent predictor of BMD (β = 0.068, p < 0.05) or BR (β = -0.079, p < 0.05). CONCLUSION Tea consumption was associated with increased bone strength in middle-aged and elderly Chinese women.

Abstract
In the present study, polyphenols from green tea (GTP), oolong tea (OTP) and black tea (BTP) were prepared by extraction with hot water and polyamide column chromatography. In antioxidant assay in vitro, each tea polyphenols exhibited potential activity; the intestinal absorption of GTP, OTP and BTP was investigated individually by Caco-2 transwell system, and each sample was poorly transported, illustrating a low transport rate for tea polyphenols through cell monolayers. The effects of GTP, OTP and BTP on human intestinal microbiota were also evaluated, and each sample induced the proliferation of certain beneficial bacteria and inhibited Bacteroides-Prevotella and Clostridium histolyticum. Moreover, the short-chain fatty acids (SCFA) produced in cultures with tea polyphenols were relatively higher. Together, these results suggested GTP, OTP and BTP may modulate the intestinal flora and generate SCFA, and contribute to the improvements of human health.

Abstract
BACKGROUND Oxidative stress plays an important role in the pathogenesis of various skin diseases. Thus, the antioxidant network of the skin relies on the uptake of exogenous antioxidants to ensure cell protection against radical formation. Green tea is one of the main sources of polyphenolic antioxidant compounds, but only few data are available on its cutaneous antioxidant effects. METHODS The radical scavenging properties of Benifuuki and Yabukita green tea were investigated in the human skin. Thirty-two participants who met the inclusion criteria were randomized to consume 3 cups per day of either Benifuuki tea, Yabukita tea, or water (control group) for 2 weeks. Electron paramagnetic resonance (EPR) spectroscopy was applied to measure the radical scavenging capacity of the skin in vivo before and after the intervention. RESULTS Both Yabukita and Benifuuki tea led to an increase in the radical scavenging activity of the skin by 28 and 29%, respectively, and the difference was significant when compared to the control group. Benifuuki tea, previously reported to be superior in bioavailability due to a highly absorbable methylated catechin, did not prove to be more effective than the common Yabukita tea. CONCLUSION The results show that green tea enhances the radical scavenging capacity of the skin and support the hypothesis that green tea may offer protection against cutaneous oxidative stress.

Abstract
Recently, we selected three tea (Camellia sinensis) cultivars that are rich in taste, epigallocatechin-3-O-gallate (EGCG) and epigallocatechin-3-O-(3-O-methyl)-gallate (EGCG3″Me) and then cultivated them through asexual propagation by cutting in the same region. In the present study, proton nuclear magnetic resonance (1H NMR)-based metabolomics was applied to characterize the metabotype and to understand the metabolic mechanism of these tea cultivars including wild type tea. Of the tea leaf metabolite variations, reverse associations of amino acid metabolism with catechin compound metabolism were found in the rich-taste, and EGCG- and EGCG3″Me-rich tea cultivars. Indeed, the metabolism of individual catechin compounds in the EGCG3″Me-rich cultivar differed from those of other tea cultivars. The current study highlights the distinct metabolism of various tea cultivars newly selected for cultivation and the important role of metabolomics in understanding the metabolic mechanism. Thus, comprehensive metabotyping is a useful method to assess and then develop a new plant cultivar.

Abstract
(-)-Epigallocatechin 3-O-(3-O-methyl) gallate (EGCG3″Me) has exhibited multiple beneficial effects on the prevention of obesity in oolong tea. However, its absorption is relatively low, and the potential to be fully utilized is not completely elucidated. Therefore, with human flora-associated (HFA) mice model, the effect of EGCG3″Me on high fat diet-induced obesity was investigated by high-throughput sequencing. The shifts in relative abundance of the dominant taxa at the phylum, family and genus levels showed the dramatically effects of EGCG3″Me. Despite significant inter-individual variation, a large increase in Bacteroidetes with concomitant decrease of Firmicutes was observed after the administration of EGCG3″Me for 8weeks, with a corresponding decrease in the Firmicutes/Bacteroidetes ratio, which reflect the modulatory effect of EGCG3″Me on intestinal microbiota. The results showed that EGCG3″Me may have prebiotic-like activity and can be used as a functional food component with potential therapeutic utility in manipulating intestinal microbiota, contributing to the prevention of gut dysbiosis.

Han BK, Park Y, Choi HS, Suh HJ. Hepatoprotective effects of soluble rice protein in primary hepatocytes and in mice. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2016; 96:685-694. [PMID: 25715660 DOI: 10.1002/jsfa.7153] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/09/2014] [Revised: 02/22/2015] [Accepted: 02/23/2015] [Indexed: 06/04/2023]
Abstract
BACKGROUND The production of rice-derived by-products has increased owing to the growing use of processed rice products. The objective of this study was to isolate highly purified proteins from a rice by-product, rice syrup meal, and to examine their hepatoprotective effects in vitro and in vivo. RESULTS Soluble rice protein (SRP70) was obtained via enzymatic processing of rice syrup meal using Termamyl SC and Alcalase. Mass spectrometry analysis showed that SRP70 contained low-molecular-weight (<600 Da) peptides. SRP70 did not affect the viability of rat primary hepatocytes and ameliorated tert-butyl hydroperoxide (t-BHP)-induced cytotoxicity. t-BHP-induced elevations in hepatocyte alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase activities were reduced by SRP70 in a dose-dependent manner. In addition, t-BHP exposure increased the level of malondialdehyde, a toxic reactive aldehyde, which was dose-dependently decreased by SRP70 treatment. These SRP70-induced decreases in biochemical parameters were also observed in vivo in mice. In particular, SRP70 increased the activities of liver antioxidant enzymes in t-BHP-treated mice, including catalase and glutathione peroxidase, as well as increasing the level of glutathione, an antioxidant peptide. SRP70-mediated activation of antioxidant enzymes was shown to be due to the up-regulation in their gene expressions, while nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) oxidase 4 (NOX4), a pro-oxidant enzyme, was down-regulated by SRP70. Hematoxylin and eosin staining also showed that SRP70 protected the liver from histopathological changes induced by t-BHP. CONCLUSION Taken together, these data showed that SRP70, which is derived from a rice-processing by-product, had hepatoprotective effects in vitro and in vivo.

[PMID: 26002426 DOI: 10.1016/j.fitote.2015.05.007] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2015] [Revised: 05/13/2015] [Accepted: 05/14/2015] [Indexed: 12/21/2022]
Abstract
As the important component of tea catechins in oolong tea, (-)-epigallocatechin 3-O-(3-O-methyl) gallate (EGCG3″Me) has exhibited various beneficial effects, however, little attention about its obesity prevention effect is available. In this study, the inhibitory effects of tea catechin monomers, including their methylated forms on the proliferation and differentiation of 3T3-L1 preadipocyte were studied. The major methylated tea catechins in oolong tea were identified as EGCG3″Me and ECG3″Me. The accumulation of triglyceride was significantly reduced in a concentration-dependent manner in groups treated with EGCG3″Me at concentrations of 20, 40 and 80μg/mL, and the accumulation of lipid was decreased to 89.42±2.66%, 64.36±3.13% and 39.37±2.79%, respectively. Both EGCG3″Me and EGCG treatments showed a significant inhibitory effect on adipogenesis, while EGCG3″Me showed a relatively higher effect than EGCG, which was contrary to the results of cytotoxic activity. For ECG and ECG3″Me, ECG3″Me also showed a relatively higher antiobesity effect and lower cytotoxic activity. The results of activity screening showed that methylated tea catechins, including EGCG3″Me and ECG3″Me inhibited the proliferation and differentiation of 3T3-L1 preadipocyte. The difference of inhibitory effects for tested compounds may be due to their structural difference (the hydroxyl group at C-3 in D ring substituted by methoxy group).
