background: diabetes mellitus is considered one of the 5 principal causes of death in the world and is recognized as a global public health issue because of its multifactorial facets affecting essential biochemical processes in the body. this study investigated the antidiabetic and antidyslipidemic activities of the aqueous extract of cochlospermum planchonii (c. planchonii) leaves in streptozo...

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...

Olive leaves are an agricultural waste of the olive-oil industry representing up to 10% of the dry weight arriving at olive mills. Disposal of this waste adds additional expense to farmers. Olive leaves have been shown to have a high concentration of phenolic compounds. In an attempt to utilize this waste product for phenolic compounds, we optimized their extraction using water-a "green" extrac...

Abstract Olea europaea L. (olive, Oleaceae) constitutes a source of many bioactive compounds, which have recognized benefits for both human health and technological purposes. The present article was carried out to evaluate the biological activity oleuropein (an ester 2-(3,4-dihydroxyphenyl) ethanol (hydroxytyrosol) has oleosidic skeleton that is common secoiridoid glucosides Oleaceae). It occur...

Pentacyclic triterpenes are secondary plant metabolites widespread in fruit peel, leaves and stem bark. In particular the lupane-, oleanane-, and ursane triterpenes display various pharmacological effects while being devoid of prominent toxicity. Therefore, these triterpenes are promising leading compounds for the development of new multi-targeting bioactive agents. Screening of 39 plant materi...

The antiatherosclerotic effect of aqueous leaves extract of Morus rubra was studied in streptozotocin-induced diabetic rats fed with atherosclerotic (Ath) diet [1.5 ml olive oil containing 8 mg (3, 20,000 IU) vitamin D2 and 40 mg cholesterol] for 5 consecutive days. A short-term toxicity assessment was also conducted in healthy rats to examine toxic effects of the extract. Oral administration o...

BACKGROUND The purposes of this study were: to determine the prevalence of sensitization and immunochemical characterization of Eleagnus angustifolia pollen (Russian olive) that belongs to the family Eleagnaceae. METHODS A total of 134 patients with rhinoconjunctivitis and/or asthma were studied. Its allergenicity, cross-reactivity with olive pollen and the presence of Ole e 1 and Ole e 4-lik...

The present study aimed to evaluate the nephroprotective effects of different doses of aqueous extract of olive leaf (OLE), vitamin E and their combination on gentamicin induced nephrotoxicity in albino rats. 54 adult healthy male rats were divided into nine groups comprising 6 animals each. Group 1 served as normal control group. All other groups (group 2 to group 9) were administered gentamic...

Phenolic composition of virgin olive oil is determined by the enzymatic and/or chemical reactions that take place during olive fruit processing. Of these enzymes, β-glucosidase activity plays a relevant role in the transformation of the phenolic glycosides present in the olive fruit, generating different secoiridoid derivatives. The main goal of the present study was to characterize olive fruit...
