Oleuropein expression in olive oils produced from drupes
Jan 15, 2008· Oleuropein in stoned olive oilsNevertheless, it should be consider that the amount of 1A in extravirgin olive oils hardly exceeds a couple of hundreds μg/kg (De Nino et al., 2005), therefore its variation does not contribute to appreciable macroscopic differences in the olive oils produced by the two different procedures. 4. Conclusions

Oleuropein, the bitter principle of olives, enhances
The results show that oleuropein dose-dependently enhance nitrite production in LPS-challenged mouse macrophages. This effect was blocked by the iNOS inhibitor L-NAME, indicating increased iNOS activity. Also, Western blot analysis of cell homogenates show that oleuropein increases iNOS expression in such cells.
Oleuropein is a glycosylated seco-iridoid, a type of phenolic bitter compound found in green olive skin, flesh, seeds, and leaves, and argan oil. The term oleuropein is derived from the botanical name of the olive tree, Olea europaea. Because of its bitter taste, oleuropein must be completely removed or decomposed to make olives edible.During processing of bitter and inedible green olives for
Oleuropein an overview ScienceDirect Topics
Oleuropein is a secoiridoid produced by secondary metabolism of plants and is present in all olive tissues. As a glycoside bearing in the aglycon two ester functions it is amenable to chemical and enzymatic degradations. The absolute amount of oleuropein in any tissue or fluid can be determined with the required sensitivity and accuracy by APCI-MS/MS by MRM applying the isotope dilution method.
Jan 01, 2010· Oleuropein can be considered a trace element in extra virgin olive oil, accounting for a few hundreds of ppb, and is a marker of quality and of best practice along the entire chain of production. Stoned oil produced with a prototype SPIA apparatus is richer than the conventional one of oleuropein.

Some reports have suggested that the consumption of olives , olive oil , and oleuropein, an olive oil polyphenol , can prevent the loss of bone mass in animal models of aging-related osteoporosis .Recent in vitro studies have shown that oleuropein, the main phenolic compound in olive leaves and fruit and a constituent of virgin olive oil, reduced the expression of PPAR-γ
Olive Oil. Virgin olive oil is a corn germerstone of MeD. Although it is a fat, olive oil contains a unique pattern of MUFAs and PUFAs united to a variety of polyphenols (mainly oleuropein aglycone and oleocanthal) that have shown promising results in experimental AD models (Rigacci, 2015).
