Oleocanthal is a natural organic compound isolated from extra virgin olive oil. It is responsible for the slightly peppery "bite" of extra virgin olive oil. Oleocanthal is a tyrosol ester and its chemical structure is related to oleuropein that is also found in olive oil.
Oleocanthal has been found to be have anti-inflammatory and antioxidant properties. Similar to classical NSAIDs, it is a non-selective inhibitor of cyclooxygenase (COX). It is suggested that long-term consumption of small quantities of oleocanthal from olive oil may be responsible in part for the low incidence of heart disease associated with a Mediterranean diet.[1]
50g of olive oil per day is thought to have the same effect as 1/10 of the adult ibuprofen dose.[2]
Furthermore it was shown to be an activator of the TRPA1 ion channel which is activated by many other dietary pungent compounds. Activation of TRPA1 by Oleocanthal is most likely responsible for the "peppery" taste of olive oil.[3]
Recently it has been demonstrated that oleocanthal shows potential as a therapeutic weapon for the treatment of inflammatory degenerative joint diseases.[4]
