| 1 | Focusing on the recent progress of tea polyphenol chemistry and perspectives显示文摘Myriad evidence attests to the health-promoting benefits of tea drinking.While there are multiple factors of tea influencing the effective biological properties,tea polyphenols are the most significant and valuable components.The chemical characterization and physical characteristics of tea polyphenols have been comprehensively studied over the previous years.Still the emergence of new chemistry in tea,particularly the property of scavenging reactive carbonyl species(RCS)and the newly discovered flavoalkaloid compounds,has drawn increasing attention.In this review,we summarize recent findings of a new class of compounds in tea-flavonoid alkaloids(flavoalkaloids),which exist in fresh tea leaves and can be generated during the process of post-harvesting,and also postulate the formation mechanism of flavoalkaloids between catechins and theanine-derived Strecker aldehyde.Additionally,we detail the up-to-date research results of tea polyphenols regarding their ability to trap RCS and their in vivo aminated metabolites to suppress advanced glycation ends products(AGEs).We further raise questions to be addressed in the near future,including the synthetic pathways for the generation of flavoalkaloids and AGEs in fresh tea leaves before processing and the concentrations of tea polyphenols that affect their RCS scavenging capability due to their pro-oxidant nature.More intensive research is warranted to elucidate the mechanisms of action underlying the biological activity of flavoalkaloids and the pharmacological application of tea polyphenols in scavenging RCS and impeding detrimental AGEs. | Shiming Li Liang Zhang Xiaochun Wan Jianfeng Zhan Chi-Tang Ho | 2022 | Food Science and Human Wellness2022，11，3： | 10 |

| 4 | Structure variety and its effects on biological activity of tea polysaccharides显示文摘Tea polysaccharides(TPSs),one of the major bioactive ingredients in tea,have been widely studied due to their variety of biological activities,including antioxidant,cancer prevention,hypoglycemia,anti-fatigue,anti-coagulant,anti-obesity and immunomodulatory effect.The biological effectiveness of TPSs has direct relation with their structures such as monosaccharide composition,molecular weight,glycosidic linkages,conformation and others,which can be influenced by tea materials,processing methods,extraction and purification procedures among others.Comparing to the study of tea polyphenols,the exploration of TPSs in structural elucidation and biofunctionality is very preliminary.Yet several factors affecting the structural change of TPSs have been studied and identified.Consequently,the variation of some TPS biological activity brought by the change of TPS structures has been evaluated and preliminary correlation of structure activity relationship of TPSs has been performed.Therefore,this review aims to serve as a summary research report regarding the influencing factors on TPSs structures and consequential effects on the biological activities of TPSs.We hope to provide updated information and systematic references for future study and functional food development of TPSs. | Ting Hu Peng Wu Jianfeng Zhan Weixin Wang Junfeng Shen Meiyan Wang Chi-Tang Ho Shiming Li | 2022 | Food Science and Human Wellness2022，11，3： | 2 |

| 7 | Multifunctional health-promoting effects of oolong tea and its products显示文摘Oolong tea,partially fermented from Camellia sinensis leaves,exhibits significant antioxidative,anti-inflammatory,and anti-cancer activities as indicated in several in vitro and in vivo studies.However,studies on health promoting effects of oolong tea and its characteristic compounds are limited.The potential efficacy of bioactives derived from oolong tea and their roles as promising anticancer agents,their cardio-protective benefits during hypoxic conditions,effects in treating allergic disorders,potential prebiotic activities,improvement of blood lipid status in human beings,effectivity as oral hypoglycemic agent in the treatment of type 2 diabetes,and their potentials to reduce the risk of obesity have been discussed in this review.These promising studies mainly gained from animal studies might broaden the consumption and usage of the phenolic-enriched oolong tea and its products in food and pharmaceutical industries.However,potential health beneficial effects of oolong tea in humans should be further complemented by large-sized,randomized double-blind and placebo-controlled trials to consolidate potential therapeutic applications. | Shuzhen Wang Ting Zeng Shuang Zhao Yu Zhu Changchun Feng Jianfeng Zhan Shiming Li Chi-Tang Ho Alexander Gosslau | 2022 | Food Science and Human Wellness2022，11，3： | 2 |
| 8 | Identification of serum metabolites enhancing inflammatory responses in COVID-19显示文摘Coronavirus disease 2019(COVID-19),caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),is characterized by a strong production of inflammatory cytokines such as TNF and IL-6,which underlie the severity of the disease.However,the molecular mechanisms responsible for such a strong immune response remains unclear.Here,utilizing targeted tandem mass spectrometry to analyze serum metabolome and lipidome in COVID-19 patients at different temporal stages,we identified that 611 metabolites(of 1,039)were significantly altered in COVID-19 patients.Among them,two metabolites,agmatine and putrescine,were prominently elevated in the serum of patients;and 2-quinolinecarboxylate was changed in a biphasic manner,elevated during early COVID-19 infection but levelled off.When tested in mouse embryonic fibroblasts(MEFs)and macrophages,these 3 metabolites were found to activate the NF-κB pathway that plays a pivotal role in governing cytokine production.Importantly,these metabolites were each able to cause strong increase of TNF and IL-6 levels when administered to wildtype mice,but not in the mice lacking NF-κB.Intriguingly,these metabolites have little effects on the activation of interferon regulatory factors(IRFs)for the production of type I interferons(IFNs)for antiviral defenses.These data suggest that circulating metabolites resulting from COVID-19 infection may act as effectors to elicit the peculiar systemic inflammatory responses,exhibiting severely strong proinflammatory cytokine production with limited induction of the interferons.Our study may provide a rationale for development of drugs to alleviate inflammation in COVID-19 patients. | Chen-Song Zhang Bingchang Zhang Mengqi Li Xiaoyan Wei Kai Gong Zhiyong Li Xiangyang Yao Jianfeng Wu Cixiong Zhang Mingxia Zhu Lei Zhang Xiufeng Sun Yi-Hong Zhan Zhengye Jiang Wenpeng Zhao Wei Zhong Xinguo Zhuang Dawang Zhou Hai-Long Piao Sheng-Cai Lin Zhanxiang Wang | 2022 | Science China(Life Sciences)2022，65，10： | 1 |

| 11 | Inhibitory effects of oxyresveratrol on ERK and Smad1/2 phosphorylation and HSC activation in preventing carbon tetrachloride-induced rat liver fibrosis显示文摘Oxyresveratrol(ORes,trans-2,4,3′,5′-tetrahydroxy stilbene)naturally exists in mulberry,grapes,peanuts and other plants.It belongs to stilbene polyphenolic family and has an extra hydroxyl group at 2-position comparing with resveratrol(Res).Hence,ORes has stronger antioxidant activity than resveratrol.In present study,we employed a rat hepatic fibrosis model induced by carbon tetrachloride(CCl_(4))and administrated ORes via gavage feeding to study the protective effects and potential mechanisms of ORes against hepatic fibrosis.We demonstrated that rat liver oxidative damage induced by CCl_(4)was significantly alleviated after ORes feeding.Furthermore,the mRNA transcription levels ofα-smooth muscle actinn(˛-SMA),desmin,and two MMPs(MMP2 and MMP9)were reduced and the expression levels of transforming growth factorβ1(TGF-β1),p-small mother against decapen-taplegic protein(Smad)1/2 and p-extracellular signal-regulated kinases(ERK)1/2 in the liver tissue down-regulated dramatically.In a parallel study with Res,ORes showed more efficacious protective effect than Res against rat liver fibrosis,which is attributed to extended conjugation system due to the extra hydroxyl group at 2-position on ORes making it more electron-rich and susceptible to oxidation than Res.Therefore,dietary consumption of mulberry and other fruits containing ORes may be beneficial in the prevention of liver fibrosis. | Guliang Yang Jianfeng Zhan Yiwen Yang Li Yuan Peilei Wang Chi-Tang Ho Shiming Li | 2021 | Food Science and Human Wellness2021，10，1： | 1 |

| 13 | Changes in Polyphenols and Antioxidant Activities of Yingshan Yunwu Tea during Digestion in Vitro显示文摘[Objectives]To explore the change rule of polyphenol content and antioxidant activity of coarse old leaves of Yingshan Yunwu Tea in the process of human digestion.[Methods]The coarse and old leaves of Yunwu tea in Yingshan,Huanggang,Hubei Province were selected as the research object,and their digestion in vitro was simulated.The total polyphenol content was determined by Folin-phenol reagent colorimetric method,and the DPPH radical scavenging activity and total antioxidant activity were determined.[Results]After simulated gastrointestinal digestion in vitro,the polyphenol content and antioxidant activity of coarse old leaf tea soup showed a downward trend.After gastrointestinal digestion,the polyphenol content in tea infusion separately decreased by 31.8%and 8.5%;the scavenging rate of DPPH free radical was 97%before digestion,decreased to 92%after gastric digestion and 65%after intestinal digestion,which decreased by 5%and 27%,respectively;after gastrointestinal digestion,the total antioxidant capacity of tea soup decreased by 4.7%and 3.1%,respectively.[Conclusions]This study provided a reference for the development and application of coarse old leaves of Yingshan Yunwu tea,and provided a reference for the nutritional value evaluation and comprehensive utilization of coarse old leaves,so as to make the best use of coarse tea leaves and reduce the waste of resources. | Ruyi ZHENG Jinjie ZHOU Wenzhuo WU Jianfeng ZHAN Peng WU Ting DING Weixin WANG | 2024 | Medicinal Plant2024，15，2： | 0 |
| 14 | Immobilization and Properties of Polyphenol Oxidase显示文摘[Objectives]This study was conducted to investigate the effects of embedding conditions on activity and catalytic properties of immobilized polyphenol oxidase.[Methods]Polyphenol oxidase was immobilized in a polymer material by the embedding method,and the optimal immobilization conditions were obtained by single factor tests:CaCl_(2) concentration 2.0%,sodium alginate concentration 2.0%,immobilization time 2 h and mass ratio of enzyme to carrier 10 mg/100 g,under which the immobilized enzyme activity was 93.33 U/g.Under the above conditions,the properties of polyphenol oxidase immobilized by sodium alginate(A-PPO)and free polyphenol oxidase were studied.[Results]The thermostability of A-PPO was better than that of the free enzyme,but the pH stability of A-PPO was inhibited.The Michaelis constant K_(m) values of free polyphenol oxidase and A-PPO were 0.37 and 0.48 mmol/L,respectively,and the maximum reaction rate V_(max) values were 0.38 and 0.51 mmol/(L·g),respectively.[Conclusions]This study provides a theoretical basis for the study of the properties of polyphenol oxidase. | Zheng LI Pan WANG Yanxi SHEN Mingfei WEI Yimin HE Aoyu JI Jianfeng ZHAN | 2021 | Agricultural Biotechnology2021，10，6： | 0 |
| 15 | Clustering residential electricity load curve via community detection in network显示文摘Performing analytics on the load curve(LC)of customers is the foundation for demand response which requires a better understanding of customers'consumption pattern(CP)by analyzing the load curve.However,the performances of previous widely-used LC clustering methods are poor in two folds:larger number of clusters,huge variances within a cluster(a CP is extracted from a cluster),bringing huge difficulty to understand the electricity consumption pattern of customers.In this paper,to improve the performance of LC clustering,a clustering framework incorporated with community detection is proposed.The framework includes three parts:network construction,community detection,and CP extraction.According to the cluster validity index(CVI),the integrated approach outperforms the previous state-of-the-art method with the same amount of clusters.And the approach needs fewer clusters to achieve the same performance measured by CVI. | 黄运有 Wang Nana Hao Tianshu Guo Xiaoxu Luo Chunjie Wang Lei Ren Rui Zhan Jianfeng | 2021 | High Technology Letters2021，27，1： | 0 |
