Human cancer cell antiproliferative and antioxidant activities of Juglans regia L.

Several studies suggest that regular consumption of nuts; mostly walnuts; may have beneficial effects against oxidative stress mediated diseases such as cardiovascular disease and cancer. Walnuts contain several phenolic compounds which are thought to contribute to their biological properties. The present study reports the total phenolic contents and antioxidant properties of methanolic and petroleum ether […]

Incidence of ochratoxin A in dried fruits and co-occurrence with aflatoxins in dried figs

Ninety eight dried figs; 53 sultanas and 20 dried apricots destined for export from Turkey to the European Union were tested for ochratoxin A (OTA) contamination utilizing immunoaffinity column clean-up and high-performance liquid chromatography (HPLC). While only 2 (4%) of the sultanas exceeded the 10 ng g(-1) maximum limit set by the EU; 28 (53%) […]

Chemical composition; and antioxidant and antimicrobial activities of three hazelnut (Corylus avellana L.) cultivars

Hazelnut (Corylus avellana L.) is a very popular dry fruit in the world being consumed in different form and presentations. In the present work; three hazelnut cultivars (cv. Daviana; Fertille de Coutard and M. Bollwiller) produced in Portugal; were characterized in respect to their chemical composition; antioxidant potential and antimicrobial activity. The samples were analysed […]

Bioactive properties and chemical composition of six walnut (Juglans regia L.) cultivars

The chemical composition; antioxidant potential and antimicrobial activity were studied in six walnuts (Juglans regia L.) cultivars (cv. Franquette; Lara; Marbot; Mayette; Mellanaise and Parisienne) produced in Portugal. Concerning their chemical composition the main constituent of fruits was fat ranging from 78.83% to 82.14%; being the nutritional value around 720kcal per 100g of fruits. Linoleic […]
