Introduction: Walnut leaf contains large amounts of antioxidants, phenolic compounds and flavonoids and the beneficial effect of these compounds in the treatment of diabetes has been shown. This study investigated the effect of cyclohexane and ethanol extract of walnut leaf on activity of sorbitol dehydrogenase (SDH) enzyme. Methods: Fifty- six adult male Sprague-Dawley rats were divided into s...

Walnut oil (WO) is a good source of a-linolenic acid. We compared the eŠects of WO and high-linoleic saŒower oil (HLSO) on the serum lipid level and atherosclerosis development in male and female apolipoprotein (apo) E-deˆcient mice. The WO diet resulted in a higher level of serum cholesterol than with HLSO. Female mice fed on the WO diet had a greater lesion area in the aortic root than did th...

OBJECTIVE To evaluate the effect of the intake of whole walnuts and walnut fractions on the oxidant status in mice. METHODS Thirty-six C57BL/6J male mice were randomized to be fed one of three diets: 1) a standard diet (control group), 2) a standard diet with 10% of whole walnuts (walnut-diet group), or 3) a standard diet with 2% of walnut skins (walnut-skin-diet group) for 8 wk. The plasma a...

C first walnut trees and orchards were planted during the Spanish mission period (around 1800), using seedlings of early varieties of Persian or English walnut (Juglans regia) chosen for their superior growth and nut quality. Since the 1890s, walnut trees in California have been propagated by grafting or budding desired cultivars onto rootstocks chosen for their adaptation to different physical...

SCOPE English walnut (Juglans regia) belongs to the most important allergenic tree nuts. Co-sensitization with birch (Betula verrucosa) pollen has been reported. We aimed to identify a walnut allergen homologous to the major birch pollen allergen Bet v 1. METHODS AND RESULTS A cDNA encoding a Bet v 1-homologous allergen (Jug r 5) in walnut kernels was cloned by RT-PCR. Jug r 5 was expressed i...

A study to mea~ure the effect of walnut scale infestation on English walnut qualityand yield has shown no differences in yield and no consistentdifferencein kernel quality between infested and non-infested trees for the four years ~f the study. Yield and quality of English walnut are not overly sensitive to walnut scale infestation and some degree of infestation can be tolerated with no measura...

The energy demand is increasing in parallel with the technological developments and population world. Fossil fuels are main source for this demand. As a result of production from fossil fuels, natural environment adversely affected. Furthermore, many countries depend on their need. Researchers have been interested alternative sources such as solar, biomass, wind. There studies investigating pyr...

Walnut (Juglans regia L.) press-cake is a residue of oil processing from which the phenolic compounds were extracted using ethanol 60 % by batch and semi-continuous operations, or ultrasound-assisted maceration in case de-oiled cake, with particular attention to variables time solid-solvent ratio. For extraction, conditions maximizing total yield (TPC) radical scavenging activity evaluated 2,2-...
