The current study investigated the toxicity of ethanol extract _Olea africana_ in mice and brine shrimp _(Artemia salina)_. Brine cytotoxicity acute were observed over 24 hours. Subacute was studied for 28 days using animal weight, organ-to-body weight ratio, hematological, biochemical histological parameters as indicators. Data analysis done Probit regression Two Way ANOVA _(p<0.05)_. letha...

The motherland of the olive is considered as east Mediterranean Basin. Turkey partly located within this basin having a rich source biodiversity. Olive growing in carried out Aegean, Marmara, Mediterranean, Southeastern Anatolia and Black Sea Regions. Climatic factors determine cultivation limits which not very selective terms soil demand. In regions where olives are grown, climate prevails. Wi...

In a grove in north-eastern Morocco 2020, severe root rot and crown symptoms were noticed on olive trees (Olea europaea). Pythium schmitthenneri was identified as the pathogen based conidia morphology cytochrome oxidase subunit II (COXII) gene sequence analysis. Koch's postulates verified by re-isolation of fungus P. from artificially inoculated seedlings after pathogenicity test. This is first...

Accumulated epidemiological, clinical and experimental evidence has indicated the beneficial health effects of the Mediterranean diet, which is typified by the consumption of virgin olive oil (VOO) as a main source of dietary fat. At the cellular level, compounds derived from various olive (Olea europaea), matrices, have demonstrated potent antioxidant and anti-inflammatory effects, which are t...

This survey was undertaken in the Errachidia province in south-eastern Morocco in order to inventory the main medicinal plants used in folk medicine to treat arterial hypertension and diabetes mellitus. Four hundred individuals who knew about and/or had used the medicinal plants for the indicated diseases, including some herbal healers, were interviewed throughout different regions of the provi...

In olive fruits, sugars are the main soluble components providing energy and acting as precursors for olive oil biosynthesis. Large quantities of glucose, fructose and galactose are often found in olive pulp. To analyze sugar transport processes in Olea europaea, a cDNA encoding a monosaccharide transporter, designated OeMST2 (Olea europaea monosaccharide transporter 2) was cloned. An open read...

The present work aims to study the interactive effect of drought stress and high vapour pressure deficit (VPD) on leaf gas exchange, and especially on mesophyll conductance to CO(2) (g(m)), in two woody species of great agronomical importance in the Mediterranean basin: Vitis vinifera L. cv. Tempranillo and Olea europaea L. cv. Manzanilla. Plants were grown in specially designed outdoor chamber...

Plant triterpenoids represent a large and structurally diverse class of natural products. A growing interest has been focused on triterpenoids over the past decade due to their beneficial effects on human health. We show here that these bioactive compounds are major constituents of several aerial parts (floral bud, leaf bud, stem, and leaf) of olive tree, a crop exploited so far almost exclusiv...
