Chlorogenic acid compounds from coffee are differentially absorbed and metabolized in humans.
Chlorogenic acids (CGA) are abundant phenolic compounds in coffee, with caffeoylquinic (CQA), feruloylquinic (FQA), and dicaffeoylquinic (diCQA) acids being the major subclasses. Despite the potential biopharmacological properties attributed to these compounds, little is known about their bioavailability in humans. In this study, we evaluated the distribution profile of the major CGA isomers an...
متن کاملChlorogenic acid and caffeic acid are absorbed in humans.
Chlorogenic acid, an ester of caffeic acid and quinic acid, is a major phenolic compound in coffee; daily intake in coffee drinkers is 0.5-1 g. Chlorogenic acid and caffeic acid are antioxidants in vitro and might therefore contribute to the prevention of cardiovascular disease. However, data on the absorption of chlorogenic acid and caffeic acid in humans are lacking. We determined the absorpt...

متن کاملAdvanced Glycation End Product Inhibitory Effect of Quercetin-3-O- Rutinoside, Isolated from Teucrium polium
Introduction Reactive oxygen species (ROS) have been shown to play a critical role in many diseases such as diabetes mellitus, cancer, Alzheimer, arteriosclerosis and other conditions. Chronic glucose levels in blood or cells of diabetic patients are known to cause oxidative damages, followed by an increasing in ROS production and/or dysfunction of antioxidant defense system (enzyme or non-enzy...
متن کاملOrange juice (poly)phenols are highly bioavailable in humans.
BACKGROUND We assessed the bioavailability of orange juice (poly)phenols by monitoring urinary flavanone metabolites and ring fission catabolites produced by the action of the colonic microbiota. OBJECTIVE Our objective was to identify and quantify metabolites and catabolites excreted in urine 0-24 h after the acute ingestion of a (poly)phenol-rich orange juice by 12 volunteers. DESIGN Twel...
