Much work has been carried out in recent years on the beneficial effect of phenolic compounds as natural antioxidants which help to neutralize free radicals. In fact, researchers have focused their attention on the pathological role of free radicals in a variety of diseases, among which the most important are atherosclerosis and cancer. Thus, among the components of the so-called 'Mediterranean...

Vascular endothelial growth factor (VEGF) triggers crucial signaling processes that regulate tumor angiogenesis and, therefore, represents an attractive target for the development of novel anticancer therapeutics. Several epidemiological studies have confirmed that abundant consumption of foods from plant origin is associated with reduced risk of developing cancers. In the Mediterranean basin, ...

Girdling (a ring of bark approximately 5 mm wide) was applied on olive mother plants to investigate its effect the rooting ability cuttings. Treatment in autumn and spring. The cuttings were then immersed for s into 2000 mg L?1 indole-3-butyric acid (IBA) a 45% v/v ethanolic solution. Thirty days after girdling, taken from girdled control shoots part just above girdle zone (basal), as well righ...

Phytophthora ramorum causes lethal canker diseases and extensive mortality in coast live oak (CLO) (Quercus agrifolia) and tanoak (Lithocarpus densiflorus). No practical controls are available for this disease in non-urban environments. Therefore, characterization of natural resistance is highly desirable. Variation in resistance to P. ramorum has been observed in CLO in both naturally infected...

plants are rich source of phenolic compounds (phenolic acids, flavonoids and tannins) that are most important natural antioxidants. in the present study two ultrasonic methods including probe and bath were used for the extraction of phenolic and flavonoid compounds from celtis australis. the effects of different extraction time including 30, 60 and 90 min (bath method) and 5, 10 and 20 min (pro...

fats and oils are made of triglycerides. the fatty acids are the main constituents of triglycerides. there are minor components present in the oils and fats that are of great importance in human health, namely tocopherols and phenolic compounds that exhibit antioxidant activities. the concentrations of these compounds vary during ripening and maturation of olives. the object of the present stud...

Beer is a complex alcoholic beverage made from barley (malt), hops, water and yeast. It is a good source of phenolic antioxidants. The majority of phenolic constituents of beer are derived from malt (70–80%), whereas about 20–30% are derived from hops. Phenolic constituents of beer represent a large structural variety and belong to the classes of simple phenols, benzoicand cinnamic acid derivat...

Extra virgin olive oil (EVOO) is one of the main ingredients Mediterranean diet. It claimed as a functional food for its unique content health-promoting compounds. Tyrosol (Tyr), Hydroxytyrosol (Htyr), and their phenolic derivatives present in EVOO show beneficial properties, identification quantification, both free form after hydrolysis more complex precursors, are important to certify quality...

The global phenolic content of argan oil and press cake samples (alimentary and cosmetic) was evaluated using the Folin-Ciocalteu colorimetric method and the phenolic composition of argan oil (alimentary and cosmetic) and press cake (alimentary) samples were analyzed by GC-MS after extraction with 80:20 (v/v) methanol:water and silylation. Identification of chromatographic peaks was made by mas...

A reliable, rapid analytical method was established for the characterization of constituents of the ethanol extract of geopropolis (EEGP) produced by Malaysian stingless bees-Heterotrigona itama-by combining ultra-high-performance liquid chromatography with quadruple time-of-flight mass spectrometry (UHPLC-Q-TOF/MS). Based on known standards, the online METLIN database, and published literature...
