Abstract
This study aimed to investigate, for the first time, the chemical composition and antioxidant activity of fluid extracts obtained from three Romanian cultivars of haskap berries (Lonicera caerulea L.) var. Loni, bitter cherries (Prunus avium var. sylvestris Ser.) var. Silva, and pomace from red grapes (Vitis vinifera L.) var. Mamaia, and their capacity to modulate in vitro steatosis, in view of developing novel anti-obesity products. Total phenolic, flavonoid, anthocyanin, and ascorbic acid content of fluid extracts was spectrophotometrically assessed and their free radical scavenging capacity was evaluated using Trolox Equivalent Antioxidant Capacity (TEAC) and free 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical inhibition assays. The Pearson coefficients showed a moderate correlation between the antioxidant activity of fluid extracts and their phenolic content, but a strong correlation between anthocyanin and ascorbic acid content. HPLC analysis identified and quantified the main phenolic compounds of chlorogenic and syringic acid, catechin, and glycosylated kaempferol, apigenin, and quercetin, in variable proportions. An in vitro experimental model of steatosis was developed in HepG2 hepatocytes treated with a mixture of free fatty acids. Cell culture analyses showed that cytocompatible concentrations of fluid extracts could significantly reduce the lipid accumulation and inhibit the reactive oxygen species, malondialdehyde, and nitric oxide secretion in stressed hepatocytes. In conclusion, these results put an emphasis on the chemical compounds' high antioxidant and liver protection capacity of unstudied fluid extracts obtained from Romanian cultivars of bitter cherries var. Silva and pomace of red grapes var. Mamaia, similar to the fluid extract of haskap berries var. Loni, in particular, the positive modulation of fat deposition next to oxidative stress and the lipid peroxidation process triggered by fatty acids in HepG2 hepatocytes. Consequently, this study indicated that these fluid extracts could be further exploited as hepatoprotective agents in liver steatosis, which provides a basis for the further development of novel extract mixtures with synergistic activity as anti-obesity products.

Abstract
Alcoholic liver disease (ALD) is a growing public health issue with high financial, social, and medical costs. Lonicera caerulea, which is rich in polyphenolic compounds, has been shown to exert anti-oxidative and anti-inflammatory effects. This study aimed to explore the effects and mechanisms of concentrated Lonicera caerulea juice (LCJ) on ALD in mice. ALD was established in mice via gradient alcohol feeding for 30 days. The mice in the experimental group were given LCJ by gavage. The reduction of aspartate transaminase (AST) and alanine transaminase (ALT) in the serum of mice indicated that LCJ has a liver-protective effect. LCJ improved the expression of AMPK, PPARα, and CPT1b in ALD mice to reduce the liver lipid content. Additionally, LCJ increased the expression of farnesoid X receptor (FXR), fibroblast growth factor 15 (FGF15), and fibroblast growth factor receptor 4 (FGFR4), which lowers the expression of cytochrome P450 7A1 (CYP7A1) and lessens bile acid deposition in the liver. In mice, LCJ improved the intestinal barrier by upregulating the expression of mucins and tight junction proteins in the small intestine. Moreover, it accelerated the restoration of microbial homeostasis in both the large and small intestines and increased short-chain fatty acids in the cecum. In conclusion, LCJ alleviates ALD by reducing liver and serum lipid accumulation and modulating the FXR-FGF15 signaling pathway mediated by gut microbes.

Abstract
The objective of this investigation was to appraise the mitigative effects of Lonicera caerulea pomace (LCP)-supplemented diets on Dextran Sulfate Sodium (DSS)-induced colitis, and to discuss the potential mechanisms. LCP, a by-product of fruit juice processing, harbors a higher content of polyphenols and dietary fiber compared to the L. caerulea pulp. In a murine model of colitis, the LCP diet attenuated the symptoms of colitis, as evidenced by the reduction in the disease activity index (DAI), extension of colon length, and amelioration of histopathological damage. The anti-inflammatory attributes of LCP were substantiated by a decrease in myeloperoxidase (MPO) activity and suppression of inflammatory cytokine expressions within the colon. Meanwhile, LCP mediated the repair of the intestinal barrier, characterized by the upregulation of gene expressions of tight junction (TJ) proteins and Muc2. Furthermore, LCP altered the composition of the gut microbiota, manifested in increased alpha diversity, enhancement of the abundance of beneficial bacteria (Akkermansia, Coprococcus and Bifidobacterium), and diminishment in the abundance of pathogenic bacteria (Escherichia, Enterococcus, Mucispirillum and Clostridium). Dietary LCP also increased the concentrations of SCFAs within the intestinal luminal contents of colitis mice. Given the affirmative impact of LCP on colitis, LCP may possess great potential in promoting intestinal health.

Abstract
Lonicera caerulea is a honeysuckle plant with a long development history. It is defined as a "homology of medicine and food" fruit because it is rich in bioactive substances. By-products (such as pomace, leaves, stems, and flowers), which also have beneficial values, will be produced during processing. Nevertheless, the reuse of derivatives and the further development of new products of Lonicera caerulea are still a challenge. Firstly, this paper traced the development history of Lonicera caerulea and summarized its primary nutrients and bioactive substances, subsequently discussed the research progress and underlying molecular mechanisms of its functional properties, and introduced the application and potential of Lonicera caerulea in the fields of food, health products, cosmetics, medicine, and materials. Finally, this paper put forward the future research direction to promote the development of the Lonicera caerulea industry. To sum up, Lonicera caerulea, as a potential raw material, can be used to produce more functional products. Besides, more in-depth clinical trials are needed to clarify the specific molecular mechanism of the practical components of Lonicera caerulea and improve the rate of development and utilization.HighlightsThe original species of Lonicera caerulea subgroup had appeared on the earth as early as the end of the third century.Lonicera caerulea has been introduced into North America since the 18th century, but the introduction process has not ended until now.Lonicera caerulea widely exists in Eurasia and North America and it has excellent cold tolerance, early maturity and ornamental.The fruits, stems, leaves and flowers of Lonicera caerulea all have bioactive value, but the specific molecular mechanism and utilization need to be improved.Lonicera caerulea has been widely used in food, medicine, health products, cosmetics and materials, but there are still great challenges.

Abstract
Sarcopenic obesity is a combination of sarcopenia and obesity. Although several herbal extracts showed improvement on sarcopenia and obesity, respectively, there are few studies on sarcopenic obesity. Lonicera caerulea (honeysuckle berry, HB) can ameliorate metabolic disorders including obesity. However, its effects on sarcopenic obesity have not been reported yet. Thus, the aim of this study was to investigate whether HB extract might have any beneficial effects on sarcopenic obesity in high-fat diet-induced mice. Forty-eight mice were classified into six groups and treated for eight weeks: (1) NC, normal diet control; (2) HC, high-fat diet control; (3) PC, high-fat diet with orlistat; (4) HB100, high-fat diet with HB extract at 100 mg/kg; (5) HB200, high-fat diet with HB extract at 200 mg/kg; and (6) HB400, high-fat diet with HB extract at 400 mg/kg. Body weight, fat accumulation, muscle mass, muscle strength, and mRNA expression of muscle atrophy were monitored. Compared with the HC group, HB administration showed anti-obesity properties. It reduced body weight gain and modulated serum biochemical parameters and tissue antioxidant enzymes. HB also increased muscle strength and muscle mass of hind legs. In addition, it decreased mRNA expression levels of Atrogin1 and MuRF1 as markers of muscle atrophy but increased PGC1α and SIRT1 as markers of muscle growth. These results suggest that HB might be effective in preventing sarcopenia associated with obesity.

Abstract
It is generally accepted that dietary phenolics from fruits are of significant importance to human health. Unfortunately, there is minimal published data on how differences in phenolic structure(s) impact biological pathways at cellular and molecular levels. We observed that haskap berry extracts isolated with ethanol:formic acid:water or phenolic subclass fractions separated using different concentrations of ethanol (40% and 100%) impacted cell growth in a positive manner. All fractions and extracts significantly increased population doubling times. All extracts and fractions reduced intracellular free radicals; however, there were differences in these effects, indicating different abilities to scavenge free radicals. The extracts and fractions also exhibited differing impacts on transcripts encoding the antioxidant enzymes (CAT, SOD1, GPX1, GSS and HMOX1) and the phosphorylation state of nuclear factor-κB (NF-κB). We further observed that extracts and fractions containing different phenolic structures had divergent impacts on the mammalian target of rapamycin (mTOR) and sirtuin 1 (SIRT1). siRNA-mediated knockdown of SIRT1 transcripts demonstrated that this enzyme is key to eliciting haskap phenolic(s) impact on cells. We postulate that phenolic synergism is of significant importance when evaluating their dietary impact.

Abstract
Lonicera caerulea L., also known as haskap or honeysuckle berry, is a fruit commonly planted in eastern Europe, Canada and Asia. The fruit was registered as a traditional food from a third country under European Union regulations only on December 2018. It is resistant to cold, pests, various soil acidities and diseases. However, its attractiveness is associated mostly with its health properties. The fruit shows anticancer, anti-inflammatory, and antioxidant activity-important factors in improving health. These features result from the diverse content of phytochemicals in honeysuckle berries with high concentrations of phytocompounds, mainly hydroxycinnamic acids, hydroxybenzoic acids, flavanols, flavones, isoflavones, flavonols, flavanones and anthocyanins but also iridoids, present in the fruit in exceptional amounts. The content and health properties of the fruit were identified to be dependent on cultivar, genotype and the place of harvesting. Great potential benefits of this nutritious food are its ability to minimize the negative effects of UV radiation, diabetes mellitus and neurodegenerative diseases, and to exert hepato- and cardioprotective activity.

Abstract
The objective of this study was to evaluate the hepatoprotective effects of blue honeysuckle (BH) on carbon tetrachloride (CCl4)-induced acute hepatic damage in mice. The experiment used a total of 60 ICR mice, which were divided into six groups. Except for the intact control groups, all groups received a single intraperitoneal injection of CCl4 after a 7 day pre-treatment period with distilled water, BH extracts, or silymarin. Twenty-four hours after the CCl4 injection, the following observations, representative of classical oxidative stress-mediated centrolobular necrotic acute liver injuries, were observed: decreased body weight; small nodule formation and enlargement on the gross inspections with related liver weight increase; elevation of serum AST and ALT, increases in hepatic lipid peroxidation and related depletion of endogenous antioxidants and antioxidative enzymes; centrolobular necrosis; increases in apoptotic markers, lipid peroxidation markers, and oxidative stress markers. However, liver damage was significantly inhibited by the pre-treatment with BH extracts. The present study demonstrated that oral administration of BH extracts prior to exposure to CCl4 conferred favorable hepatoprotective effects. These results demonstrated that BHe possessed suitable properties for use as a potent hepatoprotective medicinal food.

Abstract
In this study, Prunus padus, Lonicera caerulea, Berberis amurensis, and Ribes maximowiczianum, which are mainly distributed on Mt. Halla, Jeju Island, have been investigated for their antioxidant, antimicrobial, and antidiabetic activities. The methanol extracts of R. maximowiczianum leaves and P. padus branches exhibited significant and dose-dependent antioxidant activity including electron-donation ability and reducing power. To analyze the antimicrobial activity, each extract was tested by a serial two-fold dilution method against five selected gram-positive bacteria and four gram-negative bacteria, and this suggested that P. padus branches possessed the maximum antimicrobial activity against most of the gram-positive bacteria tested. In addition, the methanol extracts of P. padus branches exhibited the highest α-glucosidase inhibitory activity with an IC50 value of 1.0±0.1 μg/ml, indicating that P. padus is a promising source as a herbal medicine.
