Abstract
Citrus peels are rich in polymethoxylated flavones (PMFs), which have beneficial health and pharmacological properties. In this study, the profiles, variations, and biological activities of PMFs in the peel extracts of 27 Citrus varieties (eight species) native to China were investigated. UPLC-QTOF-MS/MS analysis revealed that mandarin accumulated more diversity and higher detectable PMF contents. Wangcangzhoupigan (ZPG) possessed the highest antioxidant capacity. Gailiangcheng (GLC) and Bingtangcheng (BTC), sweet oranges showed excellent inhibitory effects against pancreatic lipase and α-glucosidase, respectively. Most citrus extracts effectively inhibited the production of ROS and pro-inflammatory cytokines, while increasing the accumulation of anti-inflammatory cytokines. In addition, Limeng (LM), Cupig-oushigan (GSG), and Yanxiwanlu (YXWL) showed anti-proliferative effects against DU145 and PC3 cancer cells. This study provides a comprehensive PMF profile and biological activities of various citrus species and will benefit future functional citrus breeding practices aimed at designing plants rich in total or specific PMFs for health benefits.

Abstract
Intervention with natural products is becoming a promising obesity control strategy as healthy eating becomes increasingly popular. The present study aimed to prepare a citrus-based functional jelly (CFJ) from citrus by-products and investigate its bioactive effects in mice. The results of the CFJ preparation showed that the optimal formula of CFJ was 29.12%, 20%, and 3.61% for chenpi, orange juice, and pectin, respectively. The optimized CFJ can be personalized and designed with jelly shapes using 3D food printing technology. The evaluation of the biological activity of the CFJ showed that it was low in calories, with a total phenolic content of 12.44 ± 0.26 mg GAE/g. Moreover, the CFJ has a good free radical scavenging ability for ABTS. The results of the mouse experiments showed that the CFJ significantly suppressed the body weight gain and fat deposits with a dose-dependent effect, compared with the control group (p < 0.05). In addition, the activities of the antioxidant-related enzymes (CAT and SOD) of the mice were also enhanced after a supplementation with the CFJ. In short, the CFJ is a functional snack enriched in phenolic substances with low-calorie, antioxidant and anti-obesity properties. This work promotes the utilization of citrus by-products and the healthy development of its processing industry.

Abstract
With the growing popularity of the concept of healthy diet, modern obesity treatment is gradually shifting from surgical or pharmacological treatment to nutritional intervention. As a safe and effective measure, natural product interventions are a potential strategy of obesity management. The present study aimed to develop a kind of functional food rich in bioactive compounds (chenpi, kiwifruit, and pectin as raw materials) and investigate their bioactive effects on a mouse model. For development of functional kiwifruit jelly with chenpi (FKJ), the results of single-factor and response surface experiments showed that the optimized formulation was composed of a 30.26% addition of chenpi, 35% addition of kiwifruit juice, and 2.88% addition of pectin. The FKJ obtained with the optimal formulation could be used as a 3D printing raw material to print the desired food shapes successfully. For bioactivity evaluation of FKJ, the results with a mouse model showed that the food intake, liver weight, and adipose tissue weight were significantly decreased after administration of FKJ with dose-dependent effect compared to the CON group (p < 0.05). Meanwhile, the serum levels of several inflammatory factors (TG, IL-6, and TNF-α) were decreased and the activities of several antioxidant-related enzymes (SOD, GSH-PX, and CAT) were increased. In short, a functional kiwifruit jelly with chenpi was developed in this study. It is a functional snack food rich in active phenolic compounds, low in calories, with antioxidant and anti-inflammatory activity, and prevents fat accumulation. FKJ could well meet the needs of modern people for nutrition and health and also promote the processing and utilization of natural products, and has good development prospects in the functional food industry.

Abstract
This study investigated the protective effects of aged Pericarpium Citri Reticulatae 'Chachi' (PCR-C) on tert-butyl hydroperoxide (t-BHP)-induced oxidative damage in HepG2 cells. According to HPLC analysis, PCR-C aged 10 years (PCR-C10) had the highest flavonoids content, especially polymethoxyflavones (PMFs), compared with the fresh peel of Citrus reticulata cv. 'Chachiensis' and PCR-C aged 1, 3, and 5 years. Then, flavonoids-rich PCR-C samples and non-flavonoids-rich PCR-C samples (NF) were prepared by extracting and purifying PCR-C of different aging periods, for further cell experiments. Pretreatment with flavonoids-rich PCR-C samples (particularly PCR-C10) considerably reversed t-BHP-induced oxidative damage in HepG2 cells by improving cell viability, increasing SOD activity and GSH levels and reducing the overproduction of ROS and MDA. Correlation analysis further indicated that the accumulation of PMFs, mainly 5,6,7,4'-tetramethoxyflavone and nobiletin, was the main reason that PCR-C10 maintained the redox balance in HepG2 cells. These findings provided direct evidence for the cellular antioxidant activity of aged PCR-C and a guide for PCR-C's classification, authentication and rational use.

J Nutr Biochem 2022; 101:108943.

Abstract
Obesity and associated comorbidities are closely linked to gut microbiota dysbiosis, energy balance, and chronic inflammation. Tangeretin, a key citrus polymethoxylated flavone (PMF), is abundant in citrus fruits and has preventative and therapeutic effects for numerous diseases. The current study investigated the effects and possible mechanisms of tangeretin supplementation in preventing obesity in high-fat diet (HFD)-fed mice. Treatment of HFD-fed mice with tangeretin potently ameliorated HFD-induced body weight, liver steatosis, glucose intolerance, and insulin resistance. Tangeretin mitigated systemic chronic inflammation by reducing metabolic endotoxemia and inflammation-related gene expression in HFD-fed mice. An increased number of small brown adipocytes possessing multilocular and cytoplasmic lipid droplets and upregulation of thermogenic gene expression were observed after tangeretin treatment. 16S rRNA amplicon sequencing indicated that tangeretin markedly altered the gut microbiota composition (richness and diversity) and reversed 16 operational taxonomic units (OTUs) back to levels seen in mice consuming a normal chow diet (NCD). Notably, tangeretin decreased the ratio of Firmicutes-to-Bacteroidetes and greatly enriched Bacteroides and Lactobacillus. Overall, our results suggest that long-term supplementation with citrus tangeretin ameliorates the phenotype of obesity by improving adipose thermogenesis and reducing systemic inflammation and gut microbiota dysbiosis, which provides a good basis for studying the mechanism of tangeretin's beneficial effects.

Abstract
The prevalence of obesity has increased substantially over the last several decades and several environmental factors have accelerated this trend. Poly-methoxy flavones (PMFs) exist abundantly in the peels of citrus, and their biological activities have been broadly examined in recent years. Several studies have examined the effects of PMFs on obesity and its-related diseases. This systematic review conducted to focus on the effect of PMFs on obesity and its related conditions management. The PubMed, Google Scholar, Scopus, and Science Direct databases were searched for relevant studies published before November 2020. Out of 1,615 records screened, 16 studies met the study criteria. The range of dosage of PMFs was varied from 10 to 200 mg/kg (5-26 weeks) and 1-100 μmol (2h-8 days) across selected animal and in vitro studies, respectively. The literature reviewed shows that PMFs modulate several biological processes associated with obesity such as lipid and glucose metabolism, inflammation, energy balance, and oxidative stress by different mechanisms. All of the animal studies showed significant positive effects of PMFs on obesity by reducing body weight (e.g. reduced weight gain by 21.04%), insulin resistance, energy expenditure, inhibiting lipogenesis and reduced blood lipids (e.g. reduced total cholesterol by 23.10%, TG by 44.35% and LDL by 34.41%). The results of the reviewed in vitro studies have revealed that treatment with PMFs significantly inhibits lipid accumulation in adipocytes (e.g. reduced lipid accumulation by 55-60%) and 3T3-L1 pre-adipocyte differentiation as well by decreasing the expression of PPARγ and C/EBPα and also reduces the number and size of fat cells and reduced TG content in adipocytes by 45.67% and 23.10% and 16.08% for nobiletin, tangeretin and hesperetin, respectively. Although current evidence supports the use of PMFs as a complementary treatment in obesity, future research is needed to validate this promising treatment modality.

Abstract
Increasing energy expenditure by activating thermogenesis in brown and beige adipocytes is a critical approach to protect against obesity. Here, we investigated the action and mechanism of a natural polymethoxyflavone on adaptive thermogenesis in high-fat diet-induced obesity mouse model. Nobiletin treatment significantly ameliorated obesity, alleviated the whitening of brown adipose tissue, and promoted browning of white adipose tissue in mice fed a high-fat diet. Gut microbiota analysis and metabolomic profiling revealed that nobiletin treatment resulted in a composition shift in the gut microbiota thereby altering fermentation products acetate levels in the host feces and serum. Further, transplantation of the microbiota from nobiletin-treated mice to microbiota-depleted mice activated brown adipose tissue activity, promoted beige adipocytes formation, and improved high-fat diet-induced obesity. Our results indicate that nobiletin could be used as a dietary therapy to prevent HFD-induced obesity, and provide a potential target-specific gut microbial species-driven mechanism for activating thermogenesis in brown and beige adipocytes.

Abstract
The by-product of citrus juice processing is a huge source of bioactive compounds, especially polymethoxyflavones (PMFs) and fibers. In this study, a method for the separation and purification of PMFs from citrus pomace was established based on citrus nanoporous carbon (CNPC) enrichment. Different biomass porous carbons were synthesized, their adsorption/desorption characteristics were evaluated, and the CNPCs from the peel of Citrus tangerina Tanaka were found to be best for the enrichment of PMFs from the crude extracts of citrus pomace. Using this method, six PMF compounds including low-abundant PMFs in citrus fruits such as 5,6,7,4'-tetramethoxyflavone and 5-hydroxy-6,7,8,3',4'-pentamethoxyflavone can be simultaneously obtained, and the purities of these compounds were all higher than 95%, with the highest purity of nobiletin reaching 99.96%. Therefore, CNPCs have a great potential for the separation and purification of PMFs in citrus processing wastes, potentially improving the added value of citrus wastes. We also provide a method reference for disposing of citrus pomace in the future.

Abstract
Excessive lipid deposition, oxidative stress and inflammation in liver tissues are regarded as crucial inducers of nonalcoholic steatohepatitis (NASH), which is the most frequent chronic liver disease and closely related to obesity and insulin resistance. In this work, the preventive and therapeutic effects of Citrus reticulata Blanco (Jizigan) peel extract (JZE) on NASH induced by high fat (HF) diet and methionine choline-deficient (MCD) diet in C57BL/6 mice were investigated. We found that daily supplementation of JZE with an HF diet effectively ameliorated glucose tolerance and insulin resistance. In addition, the key indexes of lipid profiles, oxidative stress, hepatic steatosis and inflammatory factors were also ameliorated in both NASH mouse models. Furthermore, JZE treatment activated nuclear factor erythroid-2-related factor 2 (Nrf2) in the livers of diet- induced NASH mice. Our study suggests that JZE might alleviate NASH via the activation of Nrf2 signaling and that citrus Jizigan could be used as a dietary therapy for NASH and related metabolic syndrome.

Abstract
Excessive consumption of analgesic drug acetaminophen (APAP) can cause severe oxidative stress-mediated liver injury. Here, we investigated the protective effect and mechanism of aged citrus peel (Chenpi, CP), a Chinese herb usually used in foods in Asia, against APAP-induced hepatotoxicity. CP water (CP-WE), ethanolic (CP-EE), and water extraction residue ethanolic (CP-WREE) extracts were prepared. We found that CP-WREE contained higher content of bioactive flavonoids, including narirutin, nobiletin, and tangeretin, and more effectively enhanced the Nrf2 pathway in ARE-luciferase reporter gene transfected human HepG2-C8 cells. In mouse AML-12 hepatocytes, CP-WREE minimized APAP-induced damage and lipid peroxidation and increased mRNA and protein expressions of Nrf2 and its downstream defense enzymes (HO-1, NQO1, and UGT1A). CP-WREE also downregulated HDACs and DNMTs, upregulated KDMs, and increased the unmethylated Nrf2 promoter level. Additionally, CP-WREE blocked in vitro DNA methyltransferase activity. Taken together, CP-WREE might attenuate oxidative stress-induced hepatotoxicity through epigenetically regulating Nrf2-mediated cellular defense system.
