Objectives: Walnut (Juglans regia L.) kernel septum (or septa) (WKS), a traditional nutraceutical material in China, has not been explored detail. In this study, antimicrobial activity, total phenolic content (TPC) and antioxidant-oxidant status of WKS was investigated case it may be clinically important the management various complications. Methods: The extracted with ethanol Soxhlet device. T...

Walnut (Juglans regia L.) production is a developing sector in Hungarian horticulture, where preharvest fruit rot increasingly causes economic losses. Previously, fungi from the Diaporthaceae and Botryosphaeriaceae families were isolated with high incidence rotten fruits. Here, we identify these pathogens different plant parts (twigs, buds, shoots) orchards north-east of Hungary, test their pat...

Green husks are the outer layer of walnut fruits. They form part agro-residues discarded away upon nut maturity in industry. Although it is not used, research studies show that green husk a rich source natural bioactive phytochemicals. A total 83 individual phenolic compounds were identified husks, mainly consisting naphthoquinones, flavonols, and hydroxycinnamic acids. There no standard profil...

The aim of the present study was to determine content naphthoquinones (juglone and hydrojuglone glycosides) in different tissues walnut plants (Juglans regia L.) through growing season, for French cultivar 'Franquette' Slovenian 'Rubina'. Husk, leaves, bark, catkin pistillates were studied. Naphthoquinones contents catkins (male flowers) (female J. regia, have best our knowledge not been define...

Six cultivars (Franquette, Marbot, Mayette, Mellanaise, Lara, and Parisienne) of walnuts (Juglans regia L.) were collected during the 2001 crop, from Bragança, Portugal. Chemical composition, including moisture, total oil content, crude protein, ash, carbohydrates, and nutritional value, was evaluated. Fat was the predominant component, ranging from 62.3 to 66.5%. Total oil was extracted and an...

In this study, walnut genotypes that were selected during two growing seasons among thousands of seedlings analyzed in terms detailed morphometric, phenological, and chemical traits. A multivariate analysis was conducted with valuable traits for breeding selection such as morphometric traits, composition, phenological characteristics. Also, characterized by a retrotransposon-based iPBS marker s...
