INTRODUCTION The phenolic compounds present in olive leaves (Olea europaea L.) confer benefits to the human health. OBJECTIVES To review the scientific literature about the benefits of the polyphenols of olive leaves to human health. METHOD Literature review in the LILACS-BIREME, SciELO and MEDLINE databases for publications in English, Portuguese and Spanish with the descriptors "Olea euro...

This paper describes a circular economy process based on environmentally and economically sustainable procedures which was applied to the sector of olive oil processing on an industrial scale. Olea europaea L. tissues and by-products represent a renewable and low-cost source of polyphenols, in particular hydroxytyrosol (HTyr), a naturally occurring compound well known for its biological propert...

The aim of the current work was to encapsulate olive leaves extract in biodegradable poly(lactic acid) nanoparticles, characterize the nanoparticles and define the experimental parameters that affect the encapsulation procedure. Moreover, the loaded nanoparticles were incorporated in a cosmetic formulation and the stability of the formulation was studied for a three-month period of study. Poly(...

The olive leaves are well known for many useful pharmacological effects. Olive leaves extracts have antimicrobial, anti-inflammatory, anti-oxidant anti-hypertensive, anti-hypercholestermic, anti-hyperglycemic, antithrombotic, diuretic and anti-tumor properties. In this review article, we have showed huge collective medical activities of olive leaves extracts that can be applied for treating var...

     The influenza viruses are major etiologic agents of human respiratory infections, and inflict a sizable health and economic burden. This study examines the antiinfluenza virus activity of hydroalcoholic extract of olive leaves (OLHE). Olive leaves were collected from gardens around the city of Shiraz, characterized, dried, ground to powder, and its hydroalcoholic extract was prepared. The ...

The kinetics solid-liquid extraction of phenolics from wild olive leaves was elaborated using different mathematical models (Peleg, second order, Elovich, and power law model). As solvents, methanol, ethanol, ethanol:water 1:1, n-propanol, isopropanol and ethyl acetate were used. The second order model best described the solvent extraction process, followed by the Elovich model. The most effect...

The purpose of this study was to extract phenolic compounds from olive leaves of Koroneiki, Roghani and Mission varieties by maceration and Microwave-assisted extraction (MAE) methods with different solvents. Our results revealed that the extraction method, solvent and variety had a significant effect on the amount of phenolic compounds (p<0.05). In both extraction methods, Koroneiki and Missio...

This study aimed to evaluate the effect of feeding on virgin olive oil (VOO) and extra virgin olive oil (EVOO) at 50% and 100% with or without thyme leaves at 1% and 2.5% on pregnancy and lactation periods. Methods: One hundred and twenty adult female rats (120 ±5g) were randomly divided into 15 groups (n=8) for month before mating. On 19 th day of pregnancy, half of pregnant rats were weighted...

Olive leaf extracts possess broad biological activity including antimicrobial properties.Studies have provided evidence suggesting that the extracts increase activity againstdifferent pathogens. 4 Although the extract mixture show antimicrobial activity, theactive compound has not been identified. East Park Research (EPR) developed anextraction process of olive leaves that d...
