Fu brick tea theabrownin (FBTB) is a kind of biomacromolecule produced by oxidative polymerization polyphenols. Although variety diseases can be alleviated TB, its ability to treat ulcerative colitis (UC) still worth exploring. A dextran sulfate sodium (DSS)-induced chronic UC mouse model was designed first explore the alleviatory effect FBTB on and underlying mechanism sequencing fecal 16S rRNA genes, metabolomics, microbiota transplantation (FMT). Administration at 400 mg/kg bw in...
Quercetin (Que) has consistently been reported to be useful cytotoxic compound in vivo and vitro, but little is known on its metabolites. Here, we examined compared the effects of Que water-soluble metabolites, isorhamnetin (IS) isorhamnetin-3-glucuronide (I3G), human breast-cancer MCF-7 cells uncover their tumor-inhibitory mechanisms structure–function relationships. The results showed that Que, IS, I3G could dose-dependently inhibit growth cells, effect was ranked as > IS I3G. Furthermore,...
This study was designed to elucidate the colon microbiota-targeted release of nonextractable bound polyphenols (NEPs) derived from Fu brick tea and further identify possible anti-inflammatory mechanism in dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) mice. 1.5% DSS drinking water-induced C57BL/6J mice were fed rodent chow supplemented with or without 8% NEPs dietary fibers (DFs) for 37 days. The p-hydroxybenzoic acid quercetin liberated up 590.5 ± 70.6 470.5 51.6 mg/g by vitro...
This study first evaluated the protective effects of Fu brick tea water extracts (FTE) on alcoholic liver injury and its underlying mechanism in C57BL/6J mice. Oral administration FTE by oral gavage (400 mg per kg bw) for 12 weeks significantly alleviated lipid metabolism disorder, reduced activities serum ALT AST, decreased expression CYP2E1 gene, enhanced antioxidant capacities livers alcohol-fed mice (p < 0.05). also relieved alcohol-induced gut microbiota dysbiosis promoting...
Fu-brick tea (FBT) has attracted the attention of researchers because its unique nutritional value, but it remains unknown whether Eurotium cristatum, critical fungus from FBT, is responsible for observed anti-colitis effects FBT. Herein, E. cristatum on dextran sulfate sodium (DSS)-induced ulcerative colitis was first discussed. The results illustrated that oral administration inhibited DSS-induced colon damage. Microbiota analysis revealed improved intestinal homeostasis mice, especially...
Abstract The aim of this study was to select an appropriate drying technique from air-impingement jet (AIJD), hot air (HAD) and microwave (MWD) which can be combined with freeze (FD). Results showed that AIJD relatively high efficiency, low energy consumption good quality suitable FD. To further improve the technology kiwifruits, dried kiwifruit different conversion point during FD were also tested. obtained for AIJD+FD FD+AIJD lower than alone. Among products, processed by not only better...
Sand rice (Agriophyllum squarrosum) is an underutilized pseudocereal bearing edible seeds. In this study, the phenolics and antioxidant activity of sand seeds after cooking in vitro digestion were extensively investigated.Total phenolic content (TPC) was slightly increased whereas total flavonoid (TFC) decreased boiling. Furthermore, nine compounds detected uncooked seeds, with hyperoside (169.19 ± 6.59 µg g-1 dry weight (DW)), protocatechuic acid (167.46 7.21 DW), rutin (83.15 3.26 DW) as...
The present study aimed to compare the chemical and antioxidant differences between extractable non-extractable polyphenols (EPP NEPP) in commercial teas with different fermentation degrees. results showed that both content activity of NEPP were lower than EPP regardless degrees teas. One white tea, Baekho Silver Needle (BSN), had highest (58.38 ± 0.73 mg GAE/g DW) by alkaline hydrolysis, as well activities among studied. Meanwhile, hydrolysis also was most effective method extracting from...
The ongoing expansion of mushroom industries has generated enormous spent substrate with the potential for production valuable chemicals. This study aimed to investigate ultrasound-assisted extraction (UAE) fungal sterols from shiitake (Lentinula edodes) (SSS) by response surface methodology. results showed that three variables, including ultrasonic power, time, and liquid–solid ratio, had considerable influence on efficiency total ratio being highly significant process. optimal UAE...
Four extraction techniques including enzyme-assisted supercritical carbon dioxide (ESC-CO2), (SC-CO2), ultrasound-assisted (UAE) and Soxhlet (SE) were evaluated to efficiently extract the oil from Decaisnea insignis seeds in this study. Lipid profiling by GC-MS confirmed seven fatty acids six phytosterols all oils obtained, which palmitoleic acid (from 475.4 ± 12.0 SE 604.9 26.1 mg/g ESC-CO2) β-sitosterol 35.6 1.2 60.9 2.3 mg cholestanol equivalent/100 g predominated, respectively....
This study was to investigate the antioxidant activity of Komagataeibacter hansenii CGMCC 3917 in vivo and vitro. In vitro suggested that exhibited strong scavenging abilities against DPPH, ABTS, OH free radicals reducing power, suggesting significant anti-oxidant ability. supplementation mice with bacteria suspension at a dose 10 mL/kg (108 or 106 CFUs/mL) dramatically decreased elevated serum activities aspartate aminotransferase (AST) alanine (ALT) induced by alcohol treatment (p< 0.01),...
This study systematically explored the copigmentation effects of lignan extracts, eluent fractions, and individual lignans from Schisandra sphenathera chinensis fruits on anthocyanins enriched with petunidin-3-O-glucoside. The results showed that two ethanol extracts contained higher levels were more effective in reactions than their water counterparts. isolation macroporous resin rendered a large proportion 95% EtOH one which S. exhibited strongest ability to stabilize color. Meanwhile,...
Abstract The relationship between clay particle size in fine-grained sediments and the enrichment of organic matter redox degree their environment is conducive to judgment evaluation hydrocarbon generation potential sediments. grain characteristics particles surface Chaersen lake, Delong Hongyuan Lamasi Zhongnei lake Songnen Plain are revealed by light sedimentation method. On basis test, sediment chromaticity analyzed, directivity content used for estimation. It confirmed that negatively...
