Oleuropein is the pungent principle of raw olives. Oleuropein aglycone (OA) is a major phenolic compound in extra virgin olive oil and the absorbed form of oleuropein. We aimed to determine the mechanism underlying the nutritional effects of oleuropein and OA on interscapular brown adipose tissue
METHODS
The aim of the present study was to investigate the antiobesity effect of oleuropein on high-fat diet (HFD) induced body weight gain and visceral adiposity in mice, and to explore the underlying mechanisms involved.
RESULTS
C57BL/6N mice were fed with a normal diet, HFD (40% fat of total
Previously, we reported that high-fat-diet (HFD)-induced obesity stimulates melanoma progression in the B16F10 allograft model. In this study, we examined whether oleuropein (OL), the most abundant phenolic compound in olives, inhibits HFD-induced melanoma progression. Four-week-old male C57BL/6N
Oleuropein, a phenolic compound found in abundance in olive leaves, has beneficial effects on various diseases. However, it is unknown whether an oleuropein-rich diet is efficacious against type 2 diabetic phenotypes. In this study, we investigated the effects of the oleuropein-containing supplement
BACKGROUND
Olive oil and its minor constituents have been recommended as important dietary therapeutic interventions in preventive medicine. However, a question remains to be addressed: what are the effects of olive oil and its phenolic compounds on obesity-induced cardiac metabolic
Extra virgin olive oil has positive effects on health. Oleuropein is a polyphenolic compound present in olive-tree leaves, fruits (olives) and olive oil. It is responsible for the relevant organoleptic and biological properties of olive oil, including antiadipogenic properties. Thus, the effects of
Olive oil and table olives are rich sources of biophenols, which provides a unique taste, aroma and potential health benefits. Specifically, green olive drupes are enriched with oleuropein, a bioactive biophenol secoiridoid. Olive oil contains hydrolytic derivatives such as hydroxytyrosol, oleacein
Oleuropein, which is the major compound of olive leaves, has been reported to exert several pharmacological properties, including anti-cancer, antidiabetic and anti-atherosclerotic activities. The objective of this study was to evaluate the effect of oleuropein on adiponectin level in high
BACKGROUND
Olive plant leaves (Olea europaea L.) have been used for centuries in folk medicine to treat diabetes, but there are very limited data examining the effects of olive polyphenols on glucose homeostasis in humans.
OBJECTIVE
To assess the effects of supplementation with olive leaf
As the beneficial effects of the Mediterranean diet on human health are well established, the phenolic compounds in olive oil have been gaining interest. Oleuropein, a major phenolic compound in olives, is known to reduce the blood glucose levels in alloxan-induced diabetic rats and rabbits,
1. Oleuropein (Ole) is a major phenolic compound in Olea europaea, with anti-oxidative, anti-obesity, and anti-inflammatory properties. To explore the effect of Ole on the physiology and metabolism of poultry, this study, evaluated the effects of feeding low-dose Ole on the growth
The amyloid plaques and neurofibrillary tangles found in the Alzheimer's disease (AD) brain arise as a result of self-assembly into fibrillar material of amyloid-β protein (Aβ) and hyperphosphorylated tau, respectively, through a pathological process starting with the appearance of aggregation
Olive oil, an important component of the Mediterranean diet, produces cardioprotective effects, probably due to both oleic acid and the polyphenols such as oleuropein and hydroxytyrosol. Our aim in this study was to assess whether a polyphenol-enriched extract from the leaves of Olea europaea L.
Pancreatic lipase digests dietary fats by hydrolysis, which is a key enzyme for lipid absorption. Therefore, reduction of fat absorption by the inhibition of pancreatic lipase is suggested to be a therapeutic strategy for obesity. From the EtOAc-soluble fraction of the stem barks of Fraxinus
Aims. To assess the possible effect of polyphenol-rich olive extracts on lipid metabolism in medaka fish by quantifying the expression of lipogenic and lipolytic genes. Materials and methods. Adult medaka fish were maintained in tanks for five days with five extracts at 0.01% in water,
