Tyrosol is an organic compound with the formula HOC₆H₄CH₂CH₂OH. Classified as a phenylethanoid, a derivative of phenethyl alcohol, it is found in a variety of natural sources. The compound is colorless solid. The principal source in the human diet is olive oil.^[1]^[2]

Research

As an antioxidant, tyrosol may protect cells against injury due to oxidation in vitro.^[3] Although it is not as potent as other antioxidants present in olive oil (e.g., hydroxytyrosol), its higher concentration and good bioavailability indicate that it may have an important overall effect.^[4]

Tyrosol may also be cardioprotective. Tyrosol-treated animals showed significant increase in the phosphorylation of Akt, eNOS, and FOXO3a.^[5] In addition, tyrosol also induced the expression of the protein SIRT1 in the heart after myocardial infarction (MI) in a rat MI model.^[6]

Tyrosol forms esters with a variety of organic acids.^[7] For example, oleocanthal is the elenolic acid ester of tyrosol.
