Ferulic Acid Sugar Esters Are Recovered in Rat Plasma and Urine Mainly as the Sulfoglucuronide of Ferulic Acid
Journal of Nutrition
Ferulic acid sugar esters, the common form of ferulic acid (FA) in cereals, show a stronger antioxidant potential than FA in vitro. However, there is little information on their metabolism and excretion in vivo. In the present study, we investigated the metabolic derivatives of FA in the plasma, urine and feces of rats administered 70 mol/kg body of 5-O-feruloyl-L-arabinofuranose (FAA), feruloyl-arabinoxylan (FAXn) or the same molar amount of FA as a comparison. Administered FA and its sugardoi:10.1093/jn/133.5.1355 pmid:12730422 fatcat:gc7dqwspgvbctf3ckkfl54uuai
