FUNCTIONS Olea europaea ) contains a major class of polyphenols, the secoiridoides. These polyphenols, including oleuropein and derivatives, may provide protection against pathogenic microorganisms.*
Recent studies have demonstrated oleuropein’s growth inhibition of several pathogenic bacterial strains, including Salmonella typhi , Staphylococcus aureus , Escherichia coli , Klebsiella pneumoniae , and Bacillus cereus . Other studies have shown that the olive plant’s phenolics can reduce the production of toxins from Aspergillus flavus .*
Olive plant tissue has also been shown to reduce the oxidation of low density lipoproteins (LDL)*, which may explain some of the beneficial effects of a Mediterranean diet. The antioxidant potential of Olea europaea’s polyphenolic compounds, such as oleuropein, may reduce atherogenic progression associated with heart disease.* Animal studies have also demonstrated that dietary oleuropein can not only increase resistance of LDLs to oxidation, but can also support plasma levels of total, free, and esterified cholesterol. Other aspects of the olive plant’s cardioprotective properties include its vasodilator effect and its inhibition of platelet aggregation.*
The polyphenols of the olive plant also have hypoglycemic properties.*
