In pharmacokinetic plasma samples five predominant metabolites of gallic acid were tentatively characterized by HPLC-MS and absorption kinetics evaluated over 8 h for catechol-O-sulfate, 4-O-methylgallic acid-3-O-sulfate, and pyrogallol-O-sulfate, methylpyrogallol-O-sulfate, and 4-O-methylgallic acid with AUC0-8h of 9520 ± 3370, 6030 ± 1310, 5990 ± 1690, 4020 ± 1040, and 2790 ± 1190 μg/L h respectively. Plasma extraction was rapid and reproducible with superior recovery rates compared to conventional methods when ev
