RegIIIβ and RegIIIγ are antimicrobial peptides expressed in intestinal epithelial cells. Expression of these peptides is reportedly decreased by high-fat diet (HFD) and increased by indigestible oligosaccharides in mice. Clearly, these dietary regimens change the structure of intestinal microbiota. We employed an intestinal microbiota transplantation (IMT) to test whether diet-induced changes in the expression of these peptides are mediated by gut microbiota. C57BL/6J mice were fed either a normal-fat diet (NFD), a HFD, or a NFD supplemented with or without 1-kestose (KES), an indigestible oligosaccharide. Ileal RegIIIβ and RegIIIγ mRNA levels were lower in mice receiving IMT from HFD-fed mice than in those receiving NFD-fed mice and higher in mice receiving IMT from KES-supplemented mice than in those receiving the mice without KES supplementation. Western blot anal. showed that serum RegIIIβ levels changed in parallel with the ileal mRNA levels. We propose that HFD- and KES-induced changes in the ileal RegIIIβ and RegIIIγ expression and in the circulating RegIIIβ levels are mediated, at least in part, by intestinal microbiota. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9HPLC of Formula: 470-69-9).

And the article was included in Food Chemistry in 2021.COA of Formula: C18H32O16 This article mentions the following:

The concentration and reconstitution processes of grape juices can result in losing compounds associated with beverage quality. In this context, three tanks containing 50,000 L of grape juice were individually concentrated up to 68 Brix using a triple vacuum concentrator. The concentrated juice was reconstituted up to the original Brix of the whole juice (18.4). Phenolic compounds, sugars and organic acids were quantified by high-performance-liquid-chromatog. “Foxy” aromatic compounds were also quantified by gas-chromatog./mass-spectrometry. The concentration and reconstitution process resulted in significant losses (Tukey test, p < 0.01) of trans-caftaric acid, decreasing from 397.08 to 159.14 mg/L, chlorogenic-acid from 34.97 to 8.44 mg/L, aromatic furaneol compound from 9.06 to 1.93 mg/L, as well as total losses for gallic-acid, caffeic-acid, p-coumaric-acid, syringic-acid, hesperidin, pelargonidin-3-glucoside and epicatechin compounds The concentration and reconstitution of grape juice preserved the antioxidant capacity and most of the quantified compounds, with the reconstituted juice having good nutritional quality.

Many Chinese herbal medicines with tonifying effects contain high levels of inulin fructooligosaccharides. These herbal medicines have high development and utilization value because of their effects against dementia, depression, and oxidative stress; on improving learning and memory ability; and on enhancing immunity. In this study, a method was developed for the separation and simultaneous quantitation of fructose, glucose, sucrose, and ten inulin fructooligosaccharides by ultra-high-performance liquid chromatog. with evaporative light scattering detection within 10 min. Separation was performed on an Amide column with gradient elution. The calibration curves for the 13 constituents showed good linearity (R² > 0.9991). The limits of detection and quantification were 10.78-33.44 and 35.94-124.81 μg/mL, resp., and the recoveries ranged from 98.90 to 103.67%. This method was successfully used to quantify the 13 constituents in the Chinese herbal medicine Morinda officinalis. The contents of the ten inulin fructooligosaccharides ranged from 56.28 to 60.71%. This method is accurate, rapid and simple and can be used for quant. anal. in the quality control of herbal medicines and functional foods.

In this study, the performance of AgNPs-priming (20, 40, and 80 mg/L) on the seed germination, yield, and nutritional quality of Chinese cabbage were evaluated. We found that AgNPs-priming at 20 and 40 mg/L for 15 h significantly accelerated seed germination speed and seedling development. Cabbage seeds primed with different concentrations of AgNPs (0, 20, 40, and 80 mg/L) were then planted in a real soil and allowed to grow for 1 mo in greenhouse. AgNPs-priming at 40 mg/L showed significantly increased cabbage yield by 44.3%. Gas chromatog.-mass spectrometry (GC-MS) combining with sparse partial least squares-discriminant anal. (sPLS-DA) reveals that AgNPs priming altered the metabolite profile of cabbage leaves in a dose-dependent manner, decreasing carbohydrates and increasing nitrogen related compounds This indicates that the metabolic stimulation during germination stage can influence the entire life cycle of cabbage. The nutritional quality of cabbage edible leaves was evaluated by liquid chromatog. with tandem mass spectrometry (LC-MS/MS) and inductively coupled plasma-mass spectrometry (ICP-MS). Results showed that AgNPs-priming at all tested concentrations significantly increased the content of essential amino acids for several folds in cabbage leaves, including alanine, aspartic acid, glutamine, glutamic acid, histidine, isoleucine, leucine, lysine, phenylalanine, proline, serine, threonine, tyrosine, and valine. Meanwhile, AgNPs-priming (40 mg/L) significantly increased iron (Fe) content by 23.8% in cabbage leaves. Ag did not bioaccumulate in edible tissues, indicating the bio-safety of AgNPs-priming. These results suggest that AgNPs-priming is a low-cost and eco-friendly approach to increase crop yield and nutritional quality.

Application of Appel reaction to the primary alcohol groups of fructooligosaccharides: synthesis of 6,6â€?6′â€?trihalogenated 1-kestose derivatives was written by Tachrim, Zetryana Puteri;Nakamura, Tadashi;Sakihama, Yasuko;Hashidoko, Yasuyuki;Hashimoto, Makoto. And the article was included in ARKIVOC (Gainesville, FL, United States) in 2018.Electric Literature of C18H32O16 This article mentions the following:

1-kestose (O-β-D-fructofuranosyl-(2â†?)-β-D-fructofuranosyl-(2â†?)-α-D-glucopyranoside) is a potential short chain fructooligosaccharide with an inulin-type skeleton. Halogenation of 1-kestose was conducted via the Appel reaction with the use of carbon tetrahalide (CBr4 or CCl4) and triphenylphosphine, which was then followed by conventional acetylation. The per-O-acetylated form of 6,6â€?6′â€?trihalogenated derivatives of 1-kestose were conveniently isolated. Further deprotection of the per-O-acetylated form resulted in 6-, 6â€?, and 6′â€?trihalogenated derivatives The structure elucidation by one- and two-dimensional NMR established that halogenation are specific at the 6-, 6â€?, and 6′â€?position of 1-kestose primary alcs.

Impact of Grapevine Red Blotch Disease on Grape Composition of Vitis vinifera Cabernet Sauvignon, Merlot, and Chardonnay was written by Girardello, Raul C.;Cooper, Monica L.;Smith, Rhonda J.;Lerno, Larry A.;Bruce, Robert C.;Eridon, Sean;Oberholster, Anita. And the article was included in Journal of Agricultural and Food Chemistry in 2019.HPLC of Formula: 470-69-9 This article mentions the following:

Grapevine red blotch disease (GRBD) is a recently recognized viral disease that affects grapevines (Vitis vinifera L.). Currently little is known about its impact on grape composition This study focused on the impact of GRBD on grape primary and secondary metabolites (mainly phenolic compounds) of three Vitis vinifera L. cultivars during two seasons. Grapes from symptomatic red blotch diseased vines (RB (+)) mostly had lower concentration of total soluble solids (TSS) and higher titratable acidity (TA) levels when compared to grapes from healthy vines (RB (-)) at harvest. GRBD impacted grape phenolic composition by mostly decreasing anthocyanin and increasing flavonol and proanthocyanidin (PA) contents in berry skins. No major impacts were observed on seed phenolics. RB (+) grapes contained more amino and carboxylic acids, while RB (-) grapes contained more oligosaccharides, polyols, and some specific monosaccharides at harvest. The impact of GRBD on grape composition was variable and dependent on the cultivar, site, and season. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9HPLC of Formula: 470-69-9).

Polyethylene film is the most widely used plastic film in agricultural production activities, and its depolymerization products are mainly polyethylene-particles (PE-particles) of different mol. weights However, the impact of the mol. weights of the PE-particles on soil-crop microenvironment has not been elucidated. In this study, a potted microcosmic simulation system was used to evaluate the impact of low, medium and high mol. weight PE-particles on soil metabolism, microbial community structure, and crop growth. There were obvious differences in the shape and surface microstructure of PE-particles with different mol. weights Soil sucrase and peroxidase had significant responses to PE-particles of different mol. weights In the rhizosphere, the number of microorganisms and the microbial alpha diversity index increased with increasing PE-particles mol. weight Rhizobacter, Nitrospira, and Sphingomonas were the dominant microorganisms induced by PE-particles to regulate the metabolism of elements. Carbohydrate and amino acid contents in rhizosphere soils were the key factors affecting the species abundance of Lysobacter, Polyclovorans, Rhizobacter, and Sphingomonas. In plants, PE-particles treatment reduced the plant biomass and photosynthetic rate and disrupted normal mineral nutrient metabolism Different mol. weight PE-particles may therefore have adverse effects on the soil-plant system.

Oligosaccharides in Atractylodes macrocephala Koidz. (AMK) have a wide range of clin. effects, especially in terms of improving immunity. In this study, the oligosaccharide fingerprint of AMK was first established by high-performance liquid chromatog. coupled with evaporative light-scattering detection. This method was confirmed to be accurate and reliable. Twenty-six batches of samples from four regions were detected, and the oligosaccharide fingerprint similarity of AMK was evaluated (> 0.900). Second, the oligosaccharide profile of AMK was analyzed using high-performance liquid chromatog. coupled to high-resolution tandem mass spectrometry. Fourteen inulin-type oligosaccharides with a d.p. of 2-15 were identified, including sucrose, 1-kestose, and nystose. Finally, two representative compounds, 1-kestose and nystose, were selected for quantification anal. The established method had good regression equations, precision, repeatability, and stability.

And the article was included in Virulence in 2020.Product Details of 470-69-9 This article mentions the following:

Blue and green molds, the common phenotypes of post-harvest diseases in fruits, are mainly caused by Penicillium fungal species, including P. italicum, P. digitatum, and P. expansum. We sequenced and assembled the genome of a P. italicum strain, which contains 31,034,623 bp with 361 scaffolds and 627 contigs. A dual-transcriptome anal. following the infection of Valencia orange (Citrus sinensis) by P. italicum resulted in the annotation of 9,307 P. italicum genes and 24,591 Valencia orange genes. The pathogenicity of P. italicum may be due to the activation of effectors, including 51 small secreted cysteine-rich proteins, 110 carbohydrate-active enzymes, and 12 G protein-coupled receptors. Addnl., 211 metabolites related to the interactions between P. italicum and Valencia orange were identified by gas chromatog.-time of flight mass spectrog., three of which were further confirmed by ultra-high performance liquid chromatog. triple quadrupole mass spectrometry. Moreover, a correlation anal. between the metabolite contents and gene expression levels suggested that P. italicum induces carbohydrate metabolism in Valencia orange fruits as part of its infection strategy. This study provides useful information regarding the genomic determinants that drive the evolution of host specificity in Penicillium species and clarifies the host-plant specificity during the infection of Valencia orange by P. italicum. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Product Details of 470-69-9).

Yacon Smallanthus sonchifolius (Poepp.) H. Robinson leaves is traditionally consumed as herbal tea in many countries including Indonesia. This plants antidiabetic properties have been extensively researched, but studies on the responsible active compound identification are scarce. Information on the active compounds is critical for the consistency of Yacon herbal tea quality. The aim of this study was to identify α-glucosidase inhibitors in Indonesian Yacon leaves grown in two different locations using FTIR- and LC-MS/MS-based metabolomics in combination with in silico technique. Yacon leaves ethanol (50 and 95%) and water extracts were tested for α-glucosidase inhibitory activity, with the 95% ethanol extract being the most active. Geog. origins were found to have no major impact on the activity. In parallel, chem. profile of Yacon leaves extract was determined using FTIR and LC-MS/MS. Orthogonal Projection to Latent Structure (OPLS) was used to analyze both sets of data. OPLS anal. of FTIR data showed that compounds associated to α-glucosidase inhibitor activity included those with functional groups -OH, stretched CH, carbonyl, and alkene. It was consistent with the result of OPLS anal. of LC-MS/MS data, which revealed that based on their VIP and Y-related coefficient value, nystose, 1-kestose, luteolin-3-7-di-O-glucoside, and 1,3-O-dicaffeoilquinic acid isomers, strongly linked to Yacons α-glucosidase inhibitor activity. In silico study supported these findings, revealing that the four compounds were potent α-glucosidase inhibitors with docking score in the range of – 100.216 to – 115.657 kcal/mol, which are similar to acarbose (- 115.774 kcal/mol) as a reference drug. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Category: tetrahydrofurans).
