A previously developed method for measurement of oleocanthal and oleacein in olive oil by quantitative (1)H NMR was expanded to include the measurement of the monoaldehydic forms of oleuropein and ligstroside aglycons. The method was validated and applied to the study of 340 monovarietal Greek and Californian olive oils from 23 varieties and for a 3-year period. A wide variation concerning the ...

The leaves of the olive plant (Olea europaea) are rich in polyphenols, of which oleuropein and hydroxytyrosol (HT) are most characteristic. Such polyphenols have been demonstrated to favourably modify a variety of cardiovascular risk factors. The aim of the present intervention was to investigate the influence of olive leaf extract (OLE) on vascular function and inflammation in a postprandial s...

İnsanları fiziksel, sosyal ve psikolojik olarak etkileyen birçok hastalıkların başında gelen kanser, dünyada sık belirlenen ölüm nedenlerinden birisi haline gelmiştir. Bu açıdan bakıldığında, sebze, meyve, zeytinyağı gibi tüketimin daha fazla olduğu akdeniz diyeti önem taşımaktadır. Çeşitli triaçilgliseroleri içeren, az miktarda serbest yağ asidi ihtiva eden antioksidan, antikanserojen, anti-en...

Background: Oleuropein is a phenolic compound which is present in the olive leaf extract. The purpose of the present study was to investigate the neuroprotective effect of oleuropein as an antioxidant agent on the substantia nigra in aged rats. Methods: Twenty 18-month-old Wistar rats (450-550 g) were randomly divided into control and experimental groups. The experimental group received a daily...

Background and objectives: Increased oxidative stress and altered antioxidant levels play an essential role in the pathogenesis of diabetes mellitus. Menopause is associated with increased food intake, weight gain, metabolic disorders, and increased level of inflammatory and oxidative stress factors. This study evaluated effects of oleuropein extract on brain tissue and serum oxidative status i...

Background & Aim: Oleuropein has pharmacologic properties and is the main component of olive leaves which is considered to be the most pharmacologic compounds of olive (Olea europaea L.). The aim of this work was to investigate the possible using of the extract of this plant in food industry (sponge cake) in order to take advantage of its medicinal properties. Experimental: Ethanolic extract of...

Background: There is accumulating evidence that a polyphenol present in olive oil, oleuropein, has antioxidant, anti-inflammatory and anti-apoptotic effects. This study aimed at determining the anti-apoptotic effect of Oleuropein (Ole) on dexamethasone-induced apoptosis of mouse thymocytes. Method: Mice ...
