Effect of juglone from Juglans mandshurica bark activity of wood decay fungi
2009 - IRG/WP 09-30502
Juglone was extracted from Juglans mandshurica bark via vacuum-assisted steam stripping. The extract was characterized by Fourier Transform Infrared Spectroscopy (FTIR), 1H Nuclear Magnetic Resonance (NMR) and Gas chromatography/mass spectrometry (GC-MS). The extraction process was easy to perform and produced excellent yields (0.22 g juglone/100 g of bark) of a high purity extract (96.42% juglone...

A study of wood quality of Juglans nigra and hybrid walnut (MJ 209xRA) : durability against Coriolus versicolor, density and MOR
2004 - IRG/WP 04-10522
The study investigated possible effects of harvesting season on some wood properties of Juglan nigra (JN) and a hybrid walnut (MJ209xRA). The samples were taken from trees which were harvested in June July, August, November of the same year, and March in the year after to determine whether there were any significant differences in wood properties as regards the harvesting seasons. In order to test...

Evaluation and identification of extractives from Iranian walnut (Juglans regia L.) by GC/MS technique for protection of non-decay resistant species
2008 - IRG/WP 08-10670
The use of walnut extractives is interest as environment friendly wood preservatives in the wood preservation industry. In this study, organic solvents were used to remove extractives from Iranian walnut heartwood samples. The solvent was removed by rotoevaporation, and Identification of chemical compounds in the Walnut extractives was done by using GC/MS technique. The toxicity of various extract...
