BACKGROUND Phenolic compounds act as food antioxidants. One of the postulated mechanisms of action is chelation of prooxidant metals, such as iron. Although the antioxidative effect is desirable, this mechanism may impair the utilization of dietary iron. OBJECTIVE We sought to determine the effect of phenolic-rich extracts obtained from green tea or rosemary on nonheme-iron absorption. DESI...

Phenolic composition and biological activities of fruit extracts from Italian and Algerian Olea europaea L. cultivars were studied. Total phenolic and tannin contents were quantified in the extracts. Moreover 14 different phenolic compounds were identified, and their profiles showed remarkable quantitative differences among analysed extracts. Moreover antioxidant and enzymatic inhibition activi...

Background and Objective: Phenolic acids, polyphenols and flavonoids are antioxidant compounds, which act as cell protective factors against oxidative stress by trapping and inhibition of free radicals, play an important role in plants and animals health.
