Occurrence and Estimation of trans-Resveratrol in One-Year-Old Canes from Seven Major Chinese Grape Producing Regions
The concentration of trans-resveratrol in 165 grape cane samples from three major grape production regions and four large distribution centers of Chinese wild Vitis species were determined by reversed-phase high-performance liquid chromatography (HPLC). Among the different genotype groups and purpose of uses; cultivars of V. vinifera had much higher amounts of trans-resveratrol than did the […]
The influence of different nitrogen and carbon sources on mycotoxin production in Alternaria alternata
The aim of this study was to determine the influence of different carbon and nitrogen sources on the production of the mycotoxins alternariol (AOH); alternariol monomethyl ether (AME) and tenuazonic acid (TA) by Alternaria alternata at 28 °C using a semi-synthetic medium (modified Czapek-Dox broth) supplemented with nitrogen and carbon sources. Additionally the effect of […]
Effect of sweet almond oil on survival rate and plasma cholinesterase activity of aluminum phosphide-intoxicated rats
Introduction: Aluminum phosphide (ALP); as an effective pesticide and a substance used for protecting rice during storage; has become one of the commonest causes of poisoning and even suicide in developing countries including Iran and India. The authors aimed to study the efficacy of sweet almond oil as an antidote in ALP toxicity. Methods: The […]
Resveratrol Inhibits Periodontal Pathogens In Vitro
The gram-negative anaerobic bacteria A. actinomycetemcomitans (Aa) and P. gingivalis (Pg) are key components in the aetiology of periodontal disease; and associated hard-tissue destruction. Resveratrol is a phytoalexin; produced naturally by several plants when under attack by bacterial or fungal pathogens. It is found in many foods including mulberries; peanuts and the skin of labrusca […]
Effect of phytochemical concentrations on biological activities of Cranberry extracts.
Abstract: Plants of cranberry (Vaccinium macrocarpon) furnish edible fruits and derivates that have been used for the prevention and treatment of urinary tract infections. In the present work we compare two commercial extracts that contain proanthocyanins (PACs) at 4 percent and 20 percent for antimicrobial; antiproliferative; antiradical and protective properties against oxidative stress on cell […]
Phytochemical and antioxidant properties of selected fig (Ficus carica L.) accessions from the eastern Mediterranean region of Turkey.
Abstract: Fig has been a typical fruit component of the health-promoting Mediterranean diet for a very long time. Phytochemical characters and antioxidant capacity of green-; yellow-; brown-; purple-; and black-fruited fig (Ficus carica L.) accessions were investigated. In this study; total phenolics (TP); total anthocyanins (TA); fructose (FRUC); glucose (GLUC); sucrose (SUC); and variables (such […]
Glycemic and insulinemic responses to different preexercise snacks in participants with impaired fasting glucose.
PURPOSE: To compare serum glucose and insulin responses to 3 preexercise snacks before; during; and after exercise in individuals with impaired fasting glucose (IFG) and healthy (H) men. In addition; in an IFG population; the authors sought to determine whether a natural fruit snack (i.e.; raisins) yields more desirable glucose and insulin concentrations than an […]
Cranberry Proanthocyanidins Mediate Growth Arrest of Lung Cancer Cells through Modulation of Gene Expression and Rapid Induction of Apoptosis.
Abstract: Cranberries are rich in bioactive constituents purported to enhance immune function; improve urinary tract health; reduce cardiovascular disease and more recently; inhibit cancer in preclinical models. However; identification of the cranberry constituents with the strongest cancer inhibitory potential and the mechanism associated with cancer inhibition by cranberries remains to be elucidated. This study investigated […]
Effects of almond consumption on the reduction of LDL-cholesterol: a discussion of potential mechanisms and future research directions
Abstract: Diet plays a seminal role in the prevention and treatment of cardiovascular disease. Consumption of tree nuts has been shown to reduce low-density lipoprotein cholesterol (LDL-C); a primary target for coronary disease prevention; by 3-19%. Almonds have been found to have a consistent LDL-C-lowering effect in healthy individuals; and in individuals with high cholesterol […]
Targets of red grapes: oxidative damage of DNA and leukaemia cells
Abstract: Vitis vinifera is a widespread crop all over the world. The biophenols present in grapes have a remarkable influence on wine quality and also confer potential health-protecting properties to this fruit. The aim of the present work was to assess the beneficial properties of skin; seeds and pulp of red table grapes (RTG) (Vitis […]
