Geoffroea decorticans (chañar), is widely distributed throughout Northwestern Argentina. Its fruit is con-
sumed as flour, arrope or hydroalcoholic beverage. The chañar fruits flour was obtained and 39 phenolic
compounds were tentatively identified by HPLC-MS/MS n . The compounds comprised caffeic acid glyco-
sides, simple phenolics (protocatechuic acid and vanillic acid), a glycoside of vanillic acid, p-coumaric
acid and its phenethyl ester as well as free and glycosylated flavonoids. The polyphenols enriched extract
with and without gastroduodenal digestion inhibited enzymes associated with metabolic syndrome,
including a -amylase, a -glucosidase, lipase and hydroxyl methyl glutaryl CoA reductase. The polyphenolic
extract exhibited antioxidant activity by different mechanisms and inhibited the pro-inflammatory
enzymes (ciclooxygenase, lipoxygenase and phospholipase A 2 ). The polyphenolic extract did not showed
mutagenic effect by Ames test against Salmonella typhimurium TA98 and TA100 strains.
These findings add evidence that chañar fruit flour may be considered a functional food with preven-
tive properties against diseases associated with oxidative stress, inflammatory mediators and metabolic
syndrome.
