Juglone from Juglans Mandshurica Bark and its Resistance to Wood Decay Fungi
Introduction Juglone (5-hydroxy-1,4-naphthalenedione, or 5-hydroxy-1,4-naphthoquinone) occurs naturally in the leaves, roots and bark of plants in the Juglandaceae family, particularly the black walnut. It is active to against tumor and many plant diseases. There are many studies on its extraction methods. However, most methods are very complicated and the yield of juglone is very low. On the other hand, juglone is very hie-active to many species of virus, bacteria, and fungi, but the study on its bioactivity to wood decay fungi can hardly be found. Since juglone is renewable and environment-friendly, and wood preservatives are very helpful to save resources, the study is very meaningful. In this paper, juglone was extracted from Juglans mandshurica bark and the product was analyzed with Fourier Transform Infrared (FTIR) spectrometer, IH Nuclear Magnetic Resonance (NMR) and Gas chromatography/mass spectrometer (GC/MS). Meanwhile, the fundamental study on its resistance to some wood decay fungi was also performed.
