BACKGROUND Metabolic syndrome (MetS) refers to clustered cardiovascular risk factors (abdominal obesity, pre-diabetes, high blood pressure, dyslipidaemia). Therapies targeting oxidative stress may delay progression to atherosclerosis and diabetes. We investigated the anti-oxidative effect of a supplement combining red yeast rice and olive extract in patients with MetS. METHODS A double-blind,...

The valorization of food processing by-products, wastes and effluents is a challenging opportunity for the sustainable and competitive development of several relevant industrial sectors. One of the best examples of a biorefinery applied to plant processing wastes is that of the olive oil sector by-products including leaves and olive mill wastewaters (OMW). Management of OMW, in particular, has ...

Olea europaea L. commonly known as olive has been traditionally used for the prevention and treatment of many diseases since ancient times. Olive has been reported to possess a broad spectrum of pharmacological properties. In the present study we investigated the activity of aqueous extract of Olea europaea L. fruit at various concentrations on A2780, A172 and HFFF2 cell lines proliferation by ...

Medicinal plants are an important source of substances which are claimed to induce anti-inflammatory and antioxidant effects. The leaves of the olive tree (Oleaeur opaea) have been used for medicinal purposes since ancient times and research has suggested that olive leaf extracts have antimicrobial and antimutagenic properties. In this study, Olive leaf aqueous extracts were screened for their ...

background: it was shown that olive leave extract has antifungal, antibacterial and antiviral activities. the effects of ole on herpes simplex virus-1 (hsv-1) have not been systematically investigated yet. the aim of this study was to examine the in vitro effect of olive leaf hydroalcoholic extract (olhe) on hsv-1.   methods: virucidal effect and viral replication in vero cell line were studied...

seasonal accumulation and incorrect disposal of olive mill by-products may be detrimental to the environment. conversely, their proper recycling as soil amendments may be a sustainable solution. therefore, the objectives of this three-year field trial were: (i) investigating the effects of olive mill wastewater (omw) and pomace compost (pc) on plant nutritional status and yield in an organic ol...

A chitosan-based hydrophilic system containing an olive leaf extract was designed and its antioxidant capacity was evaluated. Encapsulation of olive leaf extract in chitosan microspheres was carried out by a spray-drying process. The particles obtained with this technique were found to be spherical and had a positive surface charge, which is an indicator of mucoadhesiveness. FTIR and X-ray diff...

The effects of drought on the photosynthetic characteristics of three Mediterranean plants (olive, Olea europea L.; rosemary, Rosmarinus officinalis L.; lavender, Lavandula stoechas L.) exposed to elevated UV-B irradiation in a glasshouse were investigated over a period of weeks. Drought conditions were imposed on 2-year-old plants by withholding water. During the onset of water stress, analyse...
