Increasing the level of urea and uric acid is an associated complication of diabetes mellitus. Many spices and herbs are known to be hypoglycaemic. Olea europaea belonging to the family oleaceae is widely used in herbal medicine for the treatment of diabetes. The present study was carried out to investigate the role of the alcoholic extract from leaves of olive on level of urea and uric acid in...

Some medicinal plants are used traditionally in Saudi Arabia to treat many bacterial infections. Three plants, lemongrass (Oymbopogon citrates), lantana (Lantana camara), and wild olive leaves (Olea europaea) were collected, identified, extracted with either hot water or organic solvents (methanol, diethyl ether, ethyl acetate and n-butanol) to investigate their antibacterial activities against...

Oleuropein, Hydroxytyrosol and Tyrosol are three major phenolic compounds present in olive with remarkable pharmacological effects. In this study, leaves and fruit of four olive cultivars including ‘Fishomi’, ‘Mary’, ‘Roghani’ and ‘Zard’ grown in the north of Iran were collected for comparative evaluation of the concentration of Oleuropein, Hydroxytyrosol and Tyrosol as well as antioxidant prop...

Several naturally occurring dietary polyphenols with chemopreventive or anticancer properties are topoisomerase II poisons. To identify additional phytochemicals that enhance topoisomerase II-mediated DNA cleavage, a library of 341 Mediterranean plant extracts was screened for activity against human topoisomerase IIα. An extract from Phillyrea latifolia L., a member of the olive tree family, di...

The olive tree (Olea europaea L.) is widely known for its strong tendency for alternate bearing, which severely affects the fruit yield from year to year. Microarray based gene expression analysis using RNA from olive samples (on-off years leaves and ripe-unripe fruits) are particularly useful to understand the molecular mechanisms influencing the periodicity in the olive tree. Thus, we carried...

We studied 92 patients with allergic rhinitis in Syodoshima, Japan, during the pollen season between April and June to evaluate the cross-reactivity to different antigens, including pollen from the olive tree (Olea europaea) and orchard grass (Dactylis glomerata). Olive tree pollen was present in the atmosphere for 23 days, from May 19 to June 12, 1994. Specific IgE antibodies for olive tree po...

Natural deep eutectic solvents (NADESs) considered as “green” solvents offer an efficient, safe, sustainable, and cost effective method alternative to conventional extraction while microwave assisted extraction (MAE) is a convenient, rapid, environmental friendly and efficient technique. The combination of NADESs with MAE was applied in this study for the recovery of phenolic compounds from oli...

b a ckground: we aimed to extract the ingredients from leaves of gossypium hirsutum (bt cotton) using different solvents and evaluate for potential use to control different larval stages of mosquito species, aedes aegypti and anoph eles stephensi . m e t hods: qualitative and quantitative estimation of ingredients from go. hirsutum (bt) plant extract was carried out and their inhibitory action ...
