Objective This study investigates the protective effect of proanthocyanidins extracted from C. humilis pomace by regulating hepatic glucose-lipid metabolism in streptozotocin (STZ)-induced type 2 diabetic mellitus (T2DM) mice fed a high-fat diet (HFD). Methods The antidiabetic activities of Cerasus humilis pomace proanthocyanidins (CPPs) were evaluated through fasting blood glucose (FBG), oral glucose tolerance test (OGTT), and biochemical analysis, including AST, ALT, C-peptide, and hepatic glycogen in mouse serum, TC, TG, HDL-C, and LDL-C levels in the liver, as well as MDA and SOD levels. Thereafter, transcriptomic analysis, coupled with western blot and RT-qPCR, was employed to validate the molecular mechanism by which CPPs improved T2DM pathology in mice. Results CPPs significantly attenuated body weight gain, hyperglycemia, hepatic lipid accumulation, and liver injury in T2DM mice. Transcriptomics implicated the PI3K/Akt/FoxO1 and AMPK/ACC signaling pathways in mediating CPPs’ anti-diabetic effects. Subsequently, western blot, immunohistochemistry, and RT-qPCR analyses confirmed that CPPs regulate these pathways and demonstrated significant suppression of key gluconeogenic enzymes, PEPCK and G6Pase. Conclusion CPPs can effectively ameliorate T2DM by suppressing hepatic glucolipid metabolism abnormalities, primarily through regulation of the PI3K/Akt/FoxO1 and AMPK/ACC signaling pathways.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":"16 1","pages":"13-27"},"PeriodicalIF":0.0,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147922826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preliminary research has found that these leaves contain polysaccharides and flavonoids, which possess antioxidant, hypoglycemic, and other physiological functions. But so far, blueberry leaves have not been fully studied and utilized industrially. Objective This study aimed to analyze the effects of four methods, namely hot air drying (HAD), vacuum drying (VD), vacuum freeze drying (VFD) and far-infrared drying (FIRD), on the nutrient composition and dissolution property of blueberry leaf powder (BLP). Results The results demonstrated that VFD was the optimal method for preserving the quality of blueberry leaves. Compared to the other three drying methods, the BLP treated with VFD exhibited a slower moisture reduction rate and drying rate, while achieving a rehydration ratio of 2.85 ± 0.04 mg/g. Moreover, the VFD-treated BLP showed significantly higher contents of flavonoids (19.94 ± 0.41 mg/g) and phenolics (106.23 ± 0.69 mg/g). Additionally, the BLP obtained through VFD treatment displayed the highest levels of free amino acids and reducing sugars, along with superior solubility and hydration capacity. Finally, radar chart further confirmed that VFD is the most effective method for maintaining blueberry leaf quality. Conclusion In this study, the nutritional composition and dissolution characteristics of BLP with different drying technologies were studied for the first time, and then the optimal drying method was determined, which provided a theoretical reference for the development and utilization of blueberry leaves.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":"15 3","pages":"199-210"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147880365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about PAs in C. humilis fruits. Objective This study aimed to analyze the accumulation characteristics, extraction, purification, and antioxidant activities of C. humilis PAs. Methods The total proanthocyanidins content (TPAC) and total antioxidant capacity (TAOC) of fruits of three C. humilis varieties (Jing-Ou 1, Jing-Ou 2, and Nong-Da 4) were determined. PA extraction was optimized using an orthogonal experimental design. The purification process of macroporous resin method was optimized and the purified PAs of C. humilis fruit was further refined by gelatin precipitation methods. The antioxidant capacity of C. humilis PAs before and after purification was by 2,2-biphenyl-1-picrylhydrazyl (DPPH) assay and 2, 2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assay in vitro . Results TPAC and TAOC showed a positive correlation and decreased in all three varieties as fruits ripened . After ripening, Jing-Ou 2 had the highest PAs content. The optimal solvent extraction method yielded a TPAC of 883.0 mg/100 g FW. The purity of PAs reached 47.52% using the macroporous resin method and 98.14% using gelatin precipitation. IC 50 values of the purified PAs were comparable to those of vitamin C at the same mass concentration. Conclusions In this study, C. humilis PAs were systematically investigated for the first time. Not only its dynamic changes during fruit development were analyzed, but also the extraction and purification methods were optimized. Meanwhile, its antioxidant activity was verified, which provided a theoretical basis for the development and utilization of C. humilis PAs as antioxidants in functional foods and pharmaceutical formulations and sheds light on the health benefits of the species.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":"15 1","pages":"86-97"},"PeriodicalIF":0.0,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147878270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consumers worldwide seek food products with added value based on physical and mental well-being. OBJECTIVE:This study aimed to analyze the urinary metabolome of volunteers who consumed a drink based on Costa Rican blackberries (Rubus adenotrichos) to identify the presence of urolithins and other possible bioactive compounds related to beneficial effects on health. METHODS:Fifteen healthy non-smoking male volunteers aged between 19 and 43 years old who consumed 250 ml of blackberry-based drink for breakfast for eight consecutive days were selected. Urine samples were obtained before and after drink consumption, which were submitted to analysis by Ultra-Performance Liquid Chromatography coupled to a Mass Detector (UPLC/ESI-Q-TOF-MS). Subsequently, a metabolomic analysis of the results was performed to identify the presence or absence of urolithins and other bioactive metabolites related to blackberry juice consumption. RESULTS:It was possible to detect high intensity presence of urolithin A (n = 6) and high intensity presence of both urolithin A and B (n = 5) in urine samples in several volunteers. However, finding them was impossible in others, or they were at very low intensities (n = 4). Likewise, it was possible to identify Menth-1-en-4,8 diol glucuronide and 1-O-E-Cinnamoyl-(6-arabinosylglucose) as other compounds related to the consumption of blackberries. CONCLUSIONS:The consumption of Costa Rican blackberries allowed us to demonstrate the presence of three metabotypes within the study population: 40% of strong urolithin A (UAP) producers, 33.3% of both urolithin (A and B) producers (UBP), and 26.7% of weak urolithin A producers (0P). Finally, it is recommended to carry out more research in this regard, considering a greater number of volunteers and including people of both sexes.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":"2012 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While previous studies have focused on the effects of different treatments and environmental conditions on fig cutting propagation, little attention has been paid to the specificrole and association of biochemical properties in leaves, stem bark and fruit on the rooting process. OBJECTIVE:This research explores the complex relationship between 40 biochemical traits and the rooting ability of fig cuttings. To achieve this objective, various machine learning techniques were employed, such as a random forest model, feature importance analysis, linear regression, and principal component analysis (PCA). RESULTS:The random forest model showed significant predictive ability with a classification accuracy of 100%, supported by a high kappa statistic. Feature importance analysis identified a* (a colorimetric parameter in fruit), fruit trans-ferulic acid and leaf total flavonoids as the most influential traits in determining the rooting ability of cuttings. The robustness of these findings is supported by the high R-squared value (0.9002) and low error metrics (MAE 0.7554 and MSE 0.6980) of the linear regression model built on these important traits. In parallel, PCA indicated that a*, leaf total flavonoids and fruit trans-ferulic acid were the dominant traits in samples with lower rooting percentage.

In Rubus, this type of measurements describes tolerance to high temperatures, sensitivity to heat and morphological alterations in flowering and chlorophyll content, as a result of plant stress. OBJECTIVE:\u0000The present research estimated chlorophyll fluorescence and the presence of some phenolic compounds in the leaves of three cultivars of blackberry (Rubus sp.) established in the central region of Colombia, under conditions of open air between 2400 and 2800 masl. MATERIAL AND METHODS:\u0000This was done through the measurement of chlorophyll a (Junior-PAM II modulated fluorometer), the quantification of phenolic compounds (Folin Ciocalteu), the determination of antioxidant capacity (DPPH and ABTS) and the study of phenolic profiles (UHPLC) in leaves of three blackberry cultivars. RESULTS:\u0000Cultivars R. alutaceus (0.66), R. glaucus (0.73) and R. alpinus (0.76), presented values lower than the optimum (0.83), for the parameter F v\u0000/F m\u0000. In addition, the direct relationships between the parameters that define the behavior of PSII and the accumulation of different polyphenols were described. Reference was also made to the content of phenolic compounds (ranging from 125 to 150 mg GA g–1 dw), which did not show significant statistical differences. The heat map and principal component analysis show the close relationship between the parameters that characterize the functioning of PSII and the accumulation of phenolic compounds, as a mechanism of adaptation to the adverse conditions of the blackberry cultivars studied.
