Why are walnuts toxic?
The majority of members of the Walnut family (Juglandaceae) produce a compound called “juglone” (5 hydroxy-alphanapthoquinone), which occurs naturally in all of these plants. Juglone can be produced from black walnut, pecan, hickory, and other members of the family, such as Carya, Engelhardtia, Juglans, Platycarya, and Pterocarya.
The Source of Toxicity In the walnut’s buds, nut hulls, and roots, the highest concentrations of juglone and hydrojuglone (converted to juglone by sensitive plants) occur. However, leaves and stems do contain a smaller amount. Juglone is only partially soluble in water and therefore does not grow very well in the soil.
Black walnuts contain a compound called juglone, which occurs naturally in all parts of the tree, particularly in the buds, nut hulls, and roots. The leaves and stems contain smaller amounts of juglone, which is leached into the soil after they fall.
