A liquid chromatography-mass spectrometry method was developed for the simultaneous separation, and determination of natural compounds including phenolic acids and flavonoids in the leaves of Hibiscus sabdariffa. By analyzing the UV and MS data, and comparison with authenticated standards, 10
The ethyl 5-(2'-alkoxycarbonyl-substituted phenoxy)furan-2-carboxylates (1C-13C) showed good anti-platelet aggregation,(1)) anti-allergic(2)) and anti-inflammatory activities.(2)) A series of 5-(2'-alkoxycarbonyl-substituted phenoxy)furfurals (1F-13F) were prepared for comparing the above
C5BL/6 female mice receiving dextran sodium sulfate in their drinking water develop an acute inflammatory colitis within 7d, with weight loss, histopathologic signs of inflammation, and colonic expression of inflammatory cytokines. In previous studies we have reported that increased inflammatory
OBJECTIVE
Pityriasis alba (PA) is a skin disorder characterized by finely scaly, hypopigmented patches, typical of childhood, that also represents an atopic dermatitis (AD) minor sign according to Hanifin and Rajka criteria. It may be isolated or associated with AD representing, sometimes an
From the roots of Lepidium meyenii Walpers (Brassicaceae) have been isolated and identified 2 flavonolignans, tricin 4'-O-[threo-β-guaiacyl-(7″-O-methyl)-glyceryl] ether (1) and tricin 4'-O-(erythro-β-guaiacyl-glyceryl) ether (2), along with 11 other known compounds, tricin (3), pinoresinol (4),
Furfural is used as a precursor for the manufacture of furan, furfuryl alcohol, tetrahydrofuran, and their derivatives and as an industrial solvent. Furfural is also present in numerous processed food and beverage products. NTP Toxicology and Carcinogenesis studies were conducted by administering
Maillard reaction products (MRPs), both crude and fractionated, were assessed for antioxidant potential using cell-free, in vitro 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, Fenton reaction induced deoxyribose degradation and oxygen radical absorbance capacity-fluorescein (ORACFL)
The aim of this paper is to evaluate the protective effect of 5-hydroxymethyl-2-furfural (5-HMF) on acute alcohol-induced liver oxidative injury in mice. 5-HMF, a maillard reaction product, was isolated from the fruits of Schisandra chinensis for animal experiments. Experimental ICR mice were
Spondias pinnata (Linn. f.) Kurz (Anacardiaceae) is widely distributed in tropical Asia, where it is commonly used as a vegetable and fruit, and is attracting increasing research attention. In this study, we investigated the chemical composition and the cytotoxic, antimicrobial, and
5-(Hydroxymethyl)-2-furfural is formed when reducing sugars such as fructose and sucrose are heated in the presence of amino acids. 5-(Hydroxymethyl)-2-furfural is ubiquitous in the human diet and occurs at concentrations greater than 1 g/kg in dried fruits, caramel products, certain types of fruit
A headspace solid-phase microextraction (HS-SPME) procedure based on five commercialised fibres (85 μm polyacrylate - PA, 100 μm polydimethylsiloxane - PDMS, 65 μm polydimethylsiloxane/divinylbenzene - PDMS/DVB, 70 μm carbowax/divinylbenzene - CW/DVB and 85 μm carboxen/polydimethylsiloxane -
Advanced glycation end-products (AGEs) can aggregate amid incessant inflammation, as may be available in patients with rheumatoid arthritis. d-Ribose reacts more promptly than glucose monosaccharide to the proteins and forms heterogeneous group of products known as AGEs. Obesity includes persons
Metal(II)-(furfural-L-his) complexes with a potentially bidentate furfural-L-his have been synthesized. Furfural-L-his and its Co/Ni/Cu/Zn(II)-(furfural-L-his) complexes have been optimized by DFT. The structural features were determined from their elemental analyses, molar conductance, magnetic,
Background
Genus
Miliusa (family Annonaceae), widely distributed in mainland Asia and Australia to New Guinea, has been employed in both traditional herbal uses and pharmacological medicines. Original research articles related to this genus are now available, but
The aim of this study was to investigate the effects of 5-hydroxymethyl-2-furfural (5-HMF) on liver fibrosis induced by carbon tetrachloride (CCl4) and alcohol. Male ICR mice were treated with CCl4 dissolved in olive oil (10% v/v, 2.5 μg/L) intraperitoneally (i.p.), and given at a dose of 2.5×10-5
