Therefore, the metabolic profiles of these stilbene compounds warrant further attention and investigation. The bioavailability of a nutrient or a drug is significantly influenced by ADME (absorption, distribution, metabolism and excretion). In this review, we summarize the study results of drug metabolism and pharmacokinetics (DMPK) profiles of resveratrol and its close oligomeric derivatives, including oxyresveratrol, piceatannol, pterostilbene, rhaponticin, rhapontigenin and 2,3,5,4′-tetrahydroxystilbene-2-O-β-glucopyranoside (THSG). This review also addressees explored delivery strategies, such as stilbenoids-loaded nanoparticles or Pickering emulsions, to enhance their aqueous solubility, stability, and thus bioavailability.</p> 2025-06-30T00:00:00+08:00 Copyright (c) http://www.isnff-jfb.com/index.php/JFB/article/view/415 Research progress on bioactive components and their activities in Sea buckthorn 2025-06-30T10:48:39+08:00 Chenye Gao 2027271102@qq.com Jiachen Kou 1627505078@qq.com Jinwen He 2132748689@qq.com Xiao Yu 3033237062@qq.com Yan Chen 2044274734@qq.com Jiangzhou Zhang 3231539249@qq.com Hongzhu Kong sl999888@qq.com Meijie Gu 2928659295@qq.com Xinyuan Zhu sl999888@qq.com Shuyue Shang 1990278492@qq.com Hui Zhao zhaohui@tjcu.edu.cn Liang Bai bailiang20101@163.com <p>Sea buckthorn (Hippophae rhamnoides L.) is a naturally occurring dual-use plant for both medicine and food.

Elicitors like glutamic acid, ascorbic acid, chitosan, and their combination were used on seeds to check their effects on germination, radicle length, phytochemical content, and antioxidant activity. Glutamic acid and a combination of 50 mg/kg low-molecular-weight chitosan with 5 mM glutamic acid significantly increased protein, phenol, and ascorbic acid contents. The highest DPPH radical scavenging activity (15.57%) was observed in sprouts treated with 50 mg/kg chitosan and 5 mM glutamic acid, while no notable ferric reducing antioxidant power (FRAP) activity was recorded. Elicited sprouts showed significantly higher α-amylase inhibitory activity than non-germinated seeds, with the chitosan-glutamic acid combination achieving the highest inhibition (53.92%). These findings underscore the potential of elicitors to enhance the nutritional and functional properties of cluster bean sprouts, warranting further research into specific phenolic compounds and other bioactive.</p> 2025-06-30T00:00:00+08:00 Copyright (c) http://www.isnff-jfb.com/index.php/JFB/article/view/418 Quantification of 3,3-dimethyl-1-butanol (DMB) in olive oil: a rapid and novel method 2025-06-30T08:18:29+08:00 Apostolos Kiritsakis kyritsak@gmail.com Rifat Gimatdin sl999888@qq.com Hasan Yavuz Gören sl999888@qq.com Nikos Sakellaropoulos sl999888@qq.com Konstantinos Kiritsakis sl999888@qq.com Charalampos Anousakis sl999888@qq.com Fereidoon Shahidi sl999888@qq.com Ahmet Ceyhan Goren sl999888@qq.com <p>A novel Headspace Gas Chromatography-Mass Spectrometry (HS-GC/MS) method for identifying and quantifying 3,3-dimethyl-1-butanol (DMB), a bioactive compound, in extra virgin olive oil was developed. In this study, solvents with similar properties to DΜB but potentially different molecular masses, namely isopropanol, n-butanol, n-pentanol, and 2-penthanol, were tested and 2-pentanol was selected as the internal standard due to both chromatographic separation and distinctive mass spectrum pattern. The method for DMB determination and quantification was validated according to Eurochem CITAC Guide. Sensitivity, specificity, linearity, accuracy, and precision parameters were evaluated. The validation process also included assessment of the method’s robustness and repeatability, ensuring that it produces reliable results for future analyses of olive oil. A linear regression equation was developed for 100–5,000 µg/L levels as y = x.11.462.10−6, where y is the peak area ratio, and x is the DMB concentration in µg/L with 0.9989 correlation coefficient (R2), and uncertainty budget was estimated as 8.22% at k = 2 confidence level. At the same time, the lower range of 0–100 µg/L was described with equation y = x.17.860.10−6 and 0.9983 correlation coefficient (R2). The uncertainty of the DMB measurements in extra virgin olive oil was estimated as 7.0% at a k = 2 confidence level. This new method was applied to determine the presence of DMB in various olive oil samples from Greece and Türkiye. The DMB values for olive oil samples were: N1(Plus health blue multi varietal ) 9.7 μg/L, Ν2 (Plus health DMB multi varietal)11.4 μg/L, N3 (Fyllikon first harvest organic) 8.3 μg/L, N4 (Plus health green multi varietal) 7.8 μg/L, N5 (Agourelaio early harvest organic) 6.8 μg/L, N6 (unknown) 4.8 μg/L, N7 (Armonia monovarietal organic) 4.8 μg/L and N8 (Edremit type olive oil from Kırkağaç, Manisa) 8.8 μg/L and N9 (Market product in Türkiye) 1.5 μg/L.</p> 2025-06-30T00:00:00+08:00 Copyright (c) http://www.isnff-jfb.com/index.php/JFB/article/view/419 The effect of L-carnitine and catechin together with calories restriction on the reduction of body fat and blood lipids 2025-06-30T08:19:43+08:00 Chi-Hua Yen cshe190@csh.org.tw Yohanes Tandoro y.tantoro@gmail.com Yu-Hsuan Liu sss7973@gmail.com Bo-Kai Chen gargon88@gmail.com Asif Ali aiffstpk@gmail.com You-Cheng Shen youcheng@csmu.edu.tw Chin-Kun Wang wck@csmu.edu.tw <p>Obesity has become a critical health problem worldwide, and it’s associated with other health issues. Weight loss supplement and caloriese restriction from the daily diet can be implemented to help reduce body weight. L-carnitine and catechin can help reduce body weight by upregulating fatty acid metabolism and altering lipid formation. This study was to assess the effect of L-carnitine and catechin together with calories restriction on body weight and lipid profile. 3T3-L1 cell line was used to assess the effect of L-carnitine and catechin on lipid accumulation. For the human study, a total 30 subjects with obesity were recruited and divided into 2 intervention groups, one is calories restriction group and the other one is L-carnitine and catechin together with calories restriction. Result shows that L-carnitine and catechin significantly reduced fat accumulation in the 3T3-L1 cell model. In the human study, L-carnitine and catechin together with calories restriction significantly reduced body weight, and body fat and improved the lipid profile of the subject, and showed better effect than calories restriction only.</p> 2025-06-30T00:00:00+08:00 Copyright (c) http://www.isnff-jfb.com/index.php/JFB/article/view/420 Botanicals impact the bifidogenic effect and metabolic outputs of in vitro fiber fermentation by gut-derived microbiota in individual-specific ways 2025-06-30T08:21:04+08:00 Dane G Deemer ddeemer@purdue.edu Noah Voreades noah@drinkolipop.com Peter A Bron sl999888@qq.com Stephen R Lindemann lindems@purdue.edu <p>Fortification of products frequently consumed by a large proportion of society provides an attractive strategy to close the “fiber gap” and may have the potential to concomitantly reverse the detrimental health effects exacerbated by our modern diets. Besides prebiotic fibers, products can contain other functional components, e.g. botanicals. However, most studies have investigated functional components in isolation. The impact of other components present in functional product blends on the bifidogenic effect typically exerted by prebiotic fibers are largely unexplored. Here, we investigated the fiber and botanical blends included in OLIPOP, a functional soda, in an in vitro gut fermentation model. Our data revealed that the blend of inulins and resistant dextrins promoted growth of bifidobacteria across gut microbiota from four donors, even those with small initial populations. In addition, botanicals interacted with fiber fermentation in donor-specific ways, in some cases strongly enhancing fermentation rate and production of short-chain fatty acids.</p> 2025-06-30T00:00:00+08:00 Copyright (c) http://www.isnff-jfb.com/index.php/JFB/article/view/421 Allyl isothiocyanate confers resistance against low-pH stress conditions to RGM1 gastric normal epithelial cells 2025-06-30T08:26:17+08:00 Shiho Kawaguchi queue336t0@gmail.com Akari Ishisaka ishisaka@shse.u-hyogo.ac.jp Akira Murakami akira@shse.u-hyogo.ac.jp <p>In this study, we attempted to elucidate the effects of ally isothiocyanates (AITC) on stress resistance. RGM1 cells, derived from the normal gastric mucosa of rats, were pretreated with AITC (0-30 μM) 24 hr or 48 hr prior to posttreatment with AITC (0 or 20 μM), or both. While approximately 90% of the vehicle-pretreated cells died by a posttreatment with AITC, pretreatments with AITC (10-30 μM), especially 24 hr prior and double pretreatments, exhibited striking cytoprotective effects. AITC, as a xenobiotic, increased the amounts of reactive oxygen species and insoluble proteins. On the other hand, double pretreatments with AITC markedly upregulated the mRNA expression levels of anti-oxidative, detoxification, and molecular chaperone genes for homeostasis. Interestingly, pretreatments with AITC (10 and 15 μM) significantly mitigated low-pH, but not high-pH, stress conditions, which may involve the activation of phosphoinositide 3-kinase and Na+/H+ exchanger. Taken together, we show here that multiple exposures to AITC can confer a stress resistance phenotype, including adaptation to acidic pH, by upregulating the expressions of self-defensive enzymes. Therefore, this study implies the importance of continuous ingestion of phytochemicals for efficiently increasing the stress resistance capacity against harmful chemicals.</p> 2025-06-30T00:00:00+08:00 Copyright (c)
