Abstract
Calafate is a berry with high concentration of anthocyanins and hydroxycinnamic acids that grows in South Patagonia. To date, no metabolism studies of phenolic compounds using calafate have been carried out. A calafate extract was characterized by HPLC-DAD-ESI-MS/MS. After extract administration (300â¯mg/kg), a pharmacokinetic study of phenolic compounds in gerbil plasma was performed by GC-MS/MS. Sixteen phenolic acids increased after intake. Phenylacetic acid derivatives exhibit the highest concentration, while main increase of phenolic catabolites was observed 2â¯h post-intake. 3-hydroxyphenylacetic and phenylacetic acids increased at 4-8â¯h post-intake. All catabolites found in gerbil plasma exhibit concentration peaks between 0.1 and 1â¯ÂµM, however no parental anthocyanins were detected. Establish in vivo plasmatic concentration ranges of phenolic compounds derived from polyphenol consumption following WHO recommendations, plays a key role to carry out future in vitro assays in order to correctly assign biological benefits of calafate berry consumption.
