Chlorogenic acid bioavailability largely depends on its metabolism by the gut microflora in ratsMarie Paule Gonthier
Unité des Maladies Métaboliques et Micronutriments, INRA Theix, 63122 Saint Genes Champanelle, France
J Nutr 133:1853-9. 2003..Their potential importance in explaining the biological effects of dietary polyphenols is emphasized...- Microbial aromatic acid metabolites formed in the gut account for a major fraction of the polyphenols excreted in urine of rats fed red wine polyphenolsMarie Paule Gonthier
Unité des Maladies Métaboliques et Micronutriments, INRA Theix, 63122 Saint Genes Champanelle, France
J Nutr 133:461-7. 2003..More attention should be given in the future to these microbial metabolites and their biological properties to help explain the health effects of polyphenols that are not easily absorbed through the gut barrier... - Novel liquid chromatography-electrospray ionization mass spectrometry method for the quantification in human urine of microbial aromatic acid metabolites derived from dietary polyphenolsMarie Paule Gonthier
Unité des Maladies Métaboliques et Micronutriments, INRA Theix, 63122, Saint Genes Champanelle, France
J Chromatogr B Analyt Technol Biomed Life Sci 789:247-55. 2003.... - Chocolate intake increases urinary excretion of polyphenol-derived phenolic acids in healthy human subjectsLaurent Y Rios
, INRA, , France
Am J Clin Nutr 77:912-8. 2003..CONCLUSION: The antioxidant and biological effects of chocolate may be explained not solely by the established absorption of catechin monomers but also by the absorption of microbial phenolic acid metabolites... - Metabolism of dietary procyanidins in ratsMarie-Paule Gonthier
, INRA Theix, , France
Free Radic Biol Med 35:837-44. 2003..This will have to be considered to explain the health effects of procyanidins. The contribution of their microbial metabolites should also be further investigated... - Polyphenol levels in human urine after intake of six different polyphenol-rich beveragesHideyuki Ito
, INRA, , France
Br J Nutr 94:500-9. 2005..Levels of urinary excretion suggest that chlorogenic acid, gallic acid, epicatechin, naringenin or hesperetin could be used as specific biomarkers to evaluate the consumption of coffee, wine, tea or cocoa, and citrus juices respectively... - Strawberry anthocyanins are recovered in urine as glucuro- and sulfoconjugates in humansCatherine Felgines
Laboratoire de Pharmacognosie, Faculte de Pharmacie, 63001 Clermont Ferrand, France
J Nutr 133:1296-301. 2003..This study demonstrated that anthocyanins were glucuro- and sulfo-conjugated in humans and that the main metabolite of strawberry anthocyanins in human urine was a monoglucuronide of pelargonidin...
