Enzymatic hydrolysis of oleuropein from Olea europea (olive) leaf extract and antioxidant activities.

Oleuropein (OE), the main polyphenol in olive leaf extract, is likely to decompose into hydroxytyrosol (HT) and elenolic acid under the action of light, acid, base, high temperature. In the enzymatic process, the content of OE in olive leaf extract and enzyme are key factors that affect the yield of HT. A selective enzyme was screened from among 10 enzymes with a high OE degradation rate. A sin...

Olive (Olea europaea L.) leaf extract and its main component (oleuropein) mitigate the development of morphine physical dependence in rats

Introduction: Recently, it has been demonstrated that olive leaf extract and its main component have calcium channel blocker, anti-inflammatory and anti-oxidative properties. However, the effects of olive leaf extract on opioid dependence have not yet been clarified. Methods: To develop morphine dependence, morphine was injected twice daily for 7 days according to an escalating dose in rats...

Highly potent antioxidant Olea europaea L. leaf extract affects carotid and renal haemodynamics in experimental hypertension: The role of oleuropein

Haemodynamic alterations in carotid and renal arteries are associated with the severity of target organ damage in patients with hypertension. Dietary habits, such as the Mediterranean diet, regulate blood pressure and oxidative stress, thus reduce the mortality rate due to cardiovascular diseases. In this study, our aim was to evaluate the reducing activity, antioxidant capacity and metal chela...

Hepatoprotective effects of purified oleuropein from olive leaf extract against ethanol-induced damages in the rat

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 ...

Effect of Olive Leaf Extract on the Behavioral Signs of Huntington\'s Disease and Antioxidant Enzymatic Activity in the Rat Brain

Introduction: Huntington's disease is a neurodegenerative disorder in which an increase in the global oxidative stress and a decrease in the antioxidant defense system are observed. Olea europaea's main phenolic components include oleuropein, dimethyl oleuropein, ligstroside and phenolic oleosides, which can be more than 140 mg per gram of fresh olives and 60-90 mg per gram of dried olive le...
