Zeytin (Olea europaea L.) yaprağı içerdiği önemli fenolik bileşikleri ve sergilediği çeşitli fonksiyonel terapötik özellikleri ile dikkat çekmektedir. Zeytinyağı üretiminde meyvelerin hasadı sırasında açığa çıkan bu yan ürün hasat edilen yaklaşık %10’ unu oluşturmakta değerli üründen faydalanılamamaktadır. Bu çalışmada zeytin ekstraktının klasik ekstraksiyon yöntemi elde edilerek püskürtmeli ku...

There is increasing evidence that menopause due to oxidative imbalance will lead to metabolic disorders (1). Menopause also increases food intake and body weight gain and is associated with abnormalities in lipid metabolism (2). More recent experimental studies confirm that ovariectomy cause oxidative stress and cell damage in animals (1,3,4). Steroid hormones, particularly estrogen, are natura...

introduction: oxidative stress seems to play a critical role in the degeneration of dopaminergic neurons in parkinson’s disease (pd). antioxidant compounds can deactivate and scavenge free radical. olive leaves are considered as a useful source of phenolic compounds. therefore, this study was designed to investigate the effects of methanolic olive leaf extract (ole) on neurobehavioral activity ...

We studied physiological (gas exchange and stomatal aperture) and morphological (individual leaf area and stomatal density) responses in leaves of five-year-old olive plants (Olea europaea L. cvs. Frantoio and Moraiolo) exposed to filtered air containing < 3 ppb O(3) or 100 ppb O(3) for 5 h day(-1) for 120 days in fumigation chambers. After 100 days of treatment, leaf drop and development of ne...

The OLIVE (On Line Interactive Validation Exercise) platform is dedicated to the validation of global biophysical products such as LAI (Leaf Area Index) and FAPAR (Fraction of Absorbed Photosynthetically Active Radiation). It was developed under the framework of the CEOS (Committee on Earth Observation Satellites) Land Product Validation (LPV) sub-group. OLIVE has three main objectives: (i) to ...

The possibility to improve the nutritional value of olive oil by enriching it in phenolic compounds from olive leaves (e.g., oleuropein) by ultrasonic maceration was studied. The experimental design used led to the following optimal extraction conditions: ultrasonic power of 60 W, temperature of 16°C and sonication duration of 45 min. The high total phenolic content (414.3 ± 3.2mg of oleuropein...

Oxidative stress and overwhelming free radicals associated with diabetes mellitus are likely to be linked with development of certain complication such as retinopathy, nephropathy and neuropathy. Treatment of diabetic subjects with antioxidant may be of advantage in attenuating these complications. Olive leaf (Oleaeuropaea), has been endowed with many beneficial and health promoting properties ...

Cancer protection associated with the consumption of olive products is well established, but not for leukemia. The protective effects of olive (Olea europaea L.) leaves were investigated by incubating human promyelocytic leukemia HL-60 cells with olive leaf extracts (OLEs) from seven principal Tunisian olive varieties, namely, Chemchali, Chemlali, Chétoui, Gerboui, Sayali, Zalmati and Zarrazi. ...
