The most important phenolic compound present in olive cultivars. It has a role as a neuroprotective agent, a TRPA1 channel agonist, a mTOR inhibitor, an anti-inflammatory agent, an antioxidant and a plant metabolite. It is a methyl ester, a diester, a member of catechols, a member of pyrans, a lactol and a secoiridoid. It is functionally related to an oleuropein."}]
