Modulation of strawberry/cranberry phenolic compounds glucuronidation by co-supplementation with onion: characterization of phenolic metabolites in rat plasma using an optimized μSPE−UHPLC-MS/MS method

Dudonné S, Dubé P, Pilon G, et al. J Ag Food Chem. 2014. Phenolic metabolites of fruit polyphenols were identified and quantified in vivo using an animal model of obesity. Results indicated a potential synergistic effect on bioavailability when polyphenols were administered with onion extract, a significant source of quercetin.
