We report the determination of phenolic compounds in olive leaves by reversed-phase HPLC/DAD, and the evaluation of their in vitro activity against several microorganisms that may be causal agents of human intestinal and respiratory tract infections, namely gram positive (Bacillus cereus, B. subtilis and Staphylococcus aureus), gram negative bacteria (Pseudomonas aeruginosa, Escherichia coli and Klebsiella microorganisms that may be causal agents of human intestinal and respiratory tract phenolic compounds were identified and quantified: caffeic acid, verbascoside, infections, namely gram positive (Bacillus cereus, B. subtilis and Staphylococcus aureus), oleuropein, luteolin 7-O-glucoside, rutin, apigenin 7-O-glucoside and luteolin gram negative bacteria (Pseudomonas aeruginosa, Escherichia coli and combined antibacterial and antifungal action, which suggest their great potential pneumoniae) and fungi (Candida albicans and Cryptococcus neoformans). as nutraceuticals, particularly as a source of phenolic compounds.
