The chemical composition of finished table olive products is influenced by the olive variety and the processing method used to debitter or cure table olives. Herein, a rapid ultrahigh-pressure liquid chromatography triple-quadrupole tandem mass spectrometry method, using dynamic multiple reaction monitoring, was developed for the quantitation of 12 predominant phenolic and secoiridoid compounds...

Response surface methodology (RSM) and artificial neural networks (ANN) were evaluated and compared in order to decide which method was the most appropriate to predict and optimize total phenolic content (TPC) and oleuropein yields in olive tree leaf (Oleaeuropaea) extracts, obtained after solvent-free microwave-assisted extraction (SFMAE). The SFMAE processing conditions were: microwave irradi...

Genic heterozygosity and variation were studied in the permanent translocation heterozygotes Oenothera biennis I, Oe. biennis II, Oe. biennis III, Oe. strigosa, Oe. parviflora I, Oe. parviflora II, and in the related bivalent formers Oe. argillicola and Oe. hookeri. From variation at 20 enzyme loci, we find that translocation heterozygosity for the entire chromosome complex is accompanied by on...

olives and olive oil contain large amounts of oleuropein. this phenolic compound is responsible for theirbitter taste and pungent aroma and has been recognized as a powerful hypotensive, hypoglycemic andantioxidant agent. thus, the aim of the present study was to evaluate the antioxidant properties of oleuropein on ethanol-induced oxidative damage and to examine its beneficial effects on liver ...

This study was designed to test the antidiabetic and antioxidative activities of olive leaf oleuropein and hydroxytyrosol. Diabetes in Wistar rats was induced by intraperitoneal injections of alloxan. The serum glucose and cholesterol, hepatic glycogen, the thiobarbituric acid-reactive substances (TBARS), and the components of hepatic and serum antioxidant system were examined. Diabetic rats sh...

The purpose of this investigation was to ascertain whether outcome expectancies and criminal thinking would change in offenders participating in a psychoeducational group and whether significant cross-lag (over time) correlations could be identified between outcome expectancies and criminal thinking. A sample of 121 US federal inmates completed the Psychological Inventory of Criminal Thinking S...

Olive from Olea europaea is native to the Mediterranean region and, both the oil and the fruit are some of the main components of the Mediterranean diet. The main active constituents of olive oil include oleic acid, phenolic constituents, and squalene. The main phenolic compounds, hydroxytyrosol and oleuropein, give extra-virgin olive oil its bitter, pungent taste. The present review focuses on...
