Summary In this study we investigated the influence of in vitro ‐simulated gastrointestinal digestion on bioaccessibility and antioxidant activity polyphenols from blueberries ( Vaccinium spp.). Total phenolic, anthocyanin, flavonoid content was determined, extract digesta compositions were analysed by HPLC ‐ ESI MS / . The phenolic compounds relatively stable under a gastric environment, whereas anthocyanins unstable an intestinal environment. polyphenol, greatly decreased after digestion,...
Anthocyanin, a natural antioxidant, is reported to have cytotoxicity against cancer cells; however, the mechanism remains unclear. The aim of present study was investigate by which malvidin-3-galactoside (M3G), prominent anthocyanin in blueberry, suppresses development hepatocellular carcinoma. In vitro, M3G suppressed proliferation, polarization, migration, and invasion activities HepG2 cells regulating protein expression cyclin D1, B, E, caspase-3, cleaved Bax, p-JNK, p-p38, activating...
Fatty acids in edible oil will be oxidized into aldehydes and ketones during hot processing, which produce polycyclic aromatic hydrocarbons (PAHs) other harmful substances to human health. Hazelnut was heated under different temperatures times. For each type of sample, fatty acid composition, glyceride core aldehyde (GCAs), PAHs were investigated. The correlation between these indicators analyzed by the Pearson coefficient. As main component hazelnut oil, oleic plays an essential role...
The aim of this study was the purification process polyphenols from Aronia melanocarpa (chokeberry), and parameters were optimised by adsorption desorption tests. By comparing ability chokeberry on six kinds macroporous resin, XAD-7 resin selected. Experiments prove that best static sample pH = 4.0 with 4 h adsorption; solvent is 95% ethanol (pH 7.0) 2 desorption. dynamic 9.3 bed volume (BV) loading amount at a feeding flow rate BV/h, washing column 5.8 BV water, followed subsequent elution...
High-fat diet (HFD) induces imbalance in the small intestine environment, where fat digestion and absorption mainly take place. This study aimed to elucidate mechanisms by which Lonicera caerulea polyphenols (LCP) might inhibit absorption, from perspective of microbiota epithelial barrier integrity. Male Sprague-Dawley rats were given HFD with or without co-administration LCP for 8 weeks. The results showed that supplementation significantly decreased levels serum triglycerides (TG), total...
Aronia melanocarpa anthocyanins (AMAs), as a natural plant extract, can control pathogens and are attracting increasing attention. However, at the proteomic level, antibacterial mechanism of AMAs against Escherichia coli O157: H7 remains unclear. In this study, tandem mass tag (TMT) quantitative proteomics was used to elucidate potential mechanisms E. cells. Ultrastructural observation reactive oxygen species (ROS) levels detection showed that destroyed integrity cell membrane, led...
The potential of cyanidin-3-O-galactoside (C3G) from Aronia melanocarpa in preventing high-fat diet (HFD) rats obesity was investigated. Male Sprague-Dawley (SD) were fed with a normal or HFD for 8 weeks. After successful modeling, supplemented either orlistat (30 mg/kg body weight (bw)/day) C3G (100 and 200 bw/day) Results showed that supplementation could inhibit gain reduce serum lipids, fat accumulation, Lee’s index rats. Treatment significantly decreased the levels tumor necrosis...
Abstract The polyphenol profile, antioxidant activity (particularly peroxyl radical-scavenging capacity (PSC) and cellular (CAA)) cytotoxicity of extracts from seven varieties blue honeysuckle were compared in this study. Moreover, an analysis correlations between individual profiles activities was also conducted. Seventeen components found the investigated extracts, with anthocyanins being prominent bioactive among polyphenols. Fruit peel contained higher concentrations to fruit pulp....
Introduction: Blueberries are rich sources of phenolic compounds and exhibit strong antioxidant activities a wide variety biological activities. Methods: Polyphenols were extracted from blueberry by solvent extraction method using ethanol solution. The purification polyphenols blueberries (Vaccinium spp.) macroporous resin XAD-7HP was optimized adsorption desorption tests. cellular the purified investigated. Results: data indicated that process best explained Langmuir isotherm model....
Triterpenes have shown many beneficial activities in researches, but their separation and preparation usually require multiple methods. Following an initial cleaning-up step on the AB-8 macroporous resin, a preparative high-speed counter-current chro
