The phenolic compounds of olive oil: structure, biological activity and beneficial effects on human health
2005
AbstractThe Mediterranean diet is rich in vegetables, cereals, fruit, fish, milk, wine and olive oil and has salutary biological functions. Epidemiological studies have shown a lower incidence of atherosclerosis, cardiovascular diseases and certain kinds of cancer in the Mediterranean area. Olive oil is the main source of fat, and the Mediterranean diet's healthy effects can in particular be attributed not only to the high relationship between unsaturated and saturated fatty acids in olive oil but also to the antioxidant property of its phenolic compounds. The main phenolic compounds, hydroxytyrosol and oleuropein, which give extra-virgin olive oil its bitter, pungent taste, have powerful a…
Phenolic compounds in different olive varieties
2001
Phenolic compounds in different olive varieties were determined by HPLC analysis over 2 years. Demethyloleuropein was found in only two (Coratina and Leccino) of the eight varieties studied, so it could be used as varietal marker. Elenolic acid glucoside and hydroxytyrosol can be considered indicators of maturation for olives. In fact, as the olives ripen, their tenor increases whereas oleuropein decreases. Keywords: Phenolic compounds; olive fruit; oleuropein; demethyloleuropein; 3,4-dihydroxyphenylethanol; elenolic acid glucoside
From extraction of valuable compounds to health promoting benefits of olive leaves through bioaccessibility, bioavailability and impact on gut microb…

Abstract Background The beneficial effects of olive leaves are known from ancient times. In this regard, both the olive leaves and the different preparations obtained from them (e.g. infusions, extracts) have been traditionally used for the treatment of various diseases or to alleviate the symptoms associated with different pathologies. In addition, the use of olive leaves extracts as nutraceuticals along today's continuous usage in cosmetics and medicine is common. Scope and approach Most of the health-related benefits of olive leaves have been associated to their high content in antioxidant bioactive compounds such as polyphenols, carotenoids, etc., being oleuropein and hydroxytyrosol som…
