In vitro antioxidant activities and neuronal cell protective effects of ethanol extract from roasted coffee beans were investigated. Colombia arabica coffee (Coffea arabica) green beans were roasted to give medium (230°C, 10 min), city (230°C, 12 min) and french (230°C, 15 min) coffee beans. Total phenolics in raw green beans, medium, city and french-roasted beans were 8.81±0.05, 9.77±0.03, 9.9...

The aim of this study was to assess the phenolic composition and nutraceutical potential of tinctures from fruits in two stages of maturity (F3, younger; F25, older), green husks (GH), and leaves (L) of Juglans regia L. In all extracts gallic, protocatechuic, 3-caffeoylquinic, 3-ρ-coumaroylquinic, 4-caffeoylquinic, 4-ρ-coumaroylquinic, and ρ -coumaric acids and quercetin-3-O-deoxyhexoside were ...

In order to test the effects of Svetol, a green coffee extract rich in chlorogenic acids with specific ratio between 5-caffeoylquinic acid and others caffeoylquinic acid isomers, on weight loss, 50 volunteers with body mass index superior to 25 were selected. They were randomized in two groups, control group (n = 20) receiving placebo, treated group (n = 30) receiving Svetol. Each volunteer too...

The absorption and metabolism in the small intestine of chlorogenic acid (5-O-caffeoylquinic acid), the main phenolic acid in the human diet, and of caffeic acid were studied in rats in order to determine whether chlorogenic acid is directly absorbed or hydrolysed in the small intestine. Chlorogenic and caffeic acids were perfused into a segment of ileum plus jejunum during 45 min (50 microm, 0...

In this study, caffeic acid (CA) and its three derivatives including 3-caffeoylquinic acid (3-CQA, neochlorogenic acid), 4-caffeoylquinic acid (4-CQA, cryptochlorogenic acid), and 5-caffeoylquinic acid (5-CQA, chlorogenic acid) were identified in Bupleurum chinense aerial parts using reverse-phase high-performance liquid chromatography (RP-HPLC) with photodiode array (PDA) detector, reference c...

The aim of this study was to find the chemical parameters for differentiation plum cultivars grown along fjord areas Western Norway and Eastern Norway, having specific agroclimatic conditions. Chemical analysis fruits confirmed contents 13 quantified elements, 22 sugar compounds, 11 organic acids, 19 phenolic antioxidant activity in 68 cultivars. Dominated were noted nitrogen (with maximum mean...

Previous in vitro studies the have suggested anti-inflammatory properties of caffeine. Coffee is also rich phenolic acids with several potential health benefits (chlorogenic acids), mainly 5-caffeoylquinic acid (5-CQA). The aim present study was to determine effect caffeine and 5-CQA, using concentrations comparable typical human consumption, on LPS-induced cytokine production whole blood cultu...
