Background and Objectives: A method was developed and validated for determining 15 polycyclic aromatic hydrocarbons (PAHs) in refined olive and refined pomace olive oils using high performance liquid chromatography coupled with a fluorescence detector. Materials and Methods: The sample preparation involved liquid–liquid extraction with organic solvent and low temperature clean-up. The low temp...

In this study, solid olive mill waste (SOMW) was used to obtain antioxidant compounds using solid–liquid extraction. The effect of different extraction methods, namely microwave-assisted (MAE), ultrasound-assisted (UAE), Soxhlet, and conventional solvent extraction, on the yield, total phenolics, activity SOMW extracts investigated. Untreated dried were subjected with water methanol. evaluated ...

Olive trees have been traditionally cultivated in dry conditions as it is a crop very well adapted to Mediterranean dry lands. Foliar fertilization is a widespread application method used by olive growers to correct frequent deficient levels of potassium in olive trees under rainfed conditions. Monopotassium Phosphate (MKP) is an economic and easily available fertilizer and a fast source of P a...

Background: Olive oil is a source of antioxidants and poses positive effects on human health. The objective of this study was firstly to identify and quantify the phenolics of some Algerian olive oils; secondly, the antioxidant activity of the samples was assessed. Methods: The virgin olive oils used in this study were derived from three Algerian cultivars, including Azeradj, Bouchouk, and Che...

Some olive cultivars possess high tendency to alternate bearing, which have a minus economic effect on olive industry. The experiment was performed in an olive orchard located in Shiraz region. Monthly monitoring of concentrations of unstructured carbohydrates (glucose, fructose, sucrose, mannitol and starch), protein, nitrogen, potassium and phosphorus in leaves, branches and roots of olive tr...

Olive tree is one of the most important oleaginous crops in the world, and known for having large genetic variability. Application of molecular markers is a suitable tool to investigate the genetic pool in crops. Therefore, in the current study 29 olive cultivars were tested by ten primers constituted by inter simple sequence repeats (ISSR). Plant materials were obtained from the collection of ...

the effect of in ovo injection of olive leaf extract as a growth promoter antibiotic was studied on hatchability, day old chick weight, growth rate, feed conversion ratio, mortality and carcass efficiency. three hundred and twenty eggs were divided into 4 groups, and injected on day 18. treatments consisted of: 1- control (no injection). 2- injection of 1 ml of distilled water in air sac (dw), ...

Introduction: Huntington's disease is a neurodegenerative disorder in which an increase in the global oxidative stress and a decrease in the antioxidant defense system are observed. Olea europaea's main phenolic components include oleuropein, dimethyl oleuropein, ligstroside and phenolic oleosides, which can be more than 140 mg per gram of fresh olives and 60-90 mg per gram of dried olive le...

Sphinctrina pertusa Falswal A. is described as a new species of lichenicolous fungus from India. It characterised by eight non-septate, broadly ellipsoidal, uniseriate, ascospores with olive green tint and irregular ridge like ornamentations. This growing on known lichen host Pertusaria but differs five closely related i.e., S. anglica, leucopoda, tubaeformis, turbinata, paramerae different tax...

Objective(s):Cutaneous Leishmaniasis is a common and endemic disease in Khorasan province in North-East of Iran. The pentavalant antimony (Sb V) is the mainstay of treatment that has many side effects and resistance to the drug has been reported. The microbicidal effect of ozone was proven in different microorganisms. Since there is no study in this respect and to achieve a low cost and effecti...
