Detection of contaminated hazelnuts and ground red chili pepper flakes by multispectral imaging
Mycotoxins are the toxic metabolites of certain filamentous fungi and have been demonstrated to cause various health problems in humans; including immunosuppression and cancer. Among them; the aflatoxins have received greater attention because they are potent carcinogens and are responsible for many human deaths per annum; mostly in non-industrialized countries. Various regulatory agencies have enforced […]
Alteration of Hepatic Proinflammatory Cytokines is Involved in the Resveratrol-Mediated Chemoprevention of Chemically-Induced Hepatocarcinogenesis
Abstract: Hepatocellular carcinoma (HCC); one of the most common cancers in the world; is a leading cause of cancer-related mortality. HCC develops most frequently in the background of oxidative stress and chronic hepatic inflammation due to viral infections; alcohol abuse as well as exposure to environmental and dietary carcinogens. As the prognosis of HCC is […]
Total polyphenolics and anti-oxidant properties of selected dried fruits and relationships to drying conditions
Abstract: The total polyphenolic (TPP) and antioxidant (AOX) levels of 41 Australian and imported dried fruits including sultanas (n = 22); Carina and Zante currants (n = 13); apricots (n = 3) and prunes (n = 3) were determined. Significant differences were observed among the sultanas; possibly due to local drying conditions; but not for […]
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 […]
Chemical and aroma volatile compositions of date palm (Phoenix dactylifera L.) fruits at three maturation stages
Abstract: The effect of maturity stage on the physicochemical composition and volatile components of date palm fruits (Phoenix dactylifera L.) was investigated at three different stages. Total sugars; pH; proteins and ash increased up to the full-ripe stage of all date types. On the contrary; weight; moisture and total lipids decreased across the same period. […]
