Abstract

Exhaustive ethanol-toluene of the bark and heartwood of Juglans regia L. (Juglandaceae) afforded pale red colored extractives 10 and 12% yields, respectively. Detailed chemical evaluation of these extracts using GC/MS revealed the major components in the bark and heartwood extractives to be the 3,7-dioxa-2,8- disilanonane,2,2,8,8-tetramethyl (25.17%), while the major heartwood extractives constituent was benzoic acid, 3,4,5-tri(hydroxyl)/Gallic acid (44.57%). The same components of the bark and the heartwood also contained amounts of the gallic acid, 3,7-dioxa-2,8-disilanonane, 2,2,8,8- tetramethyl, and d-glucose,2,3,4,5,6- pentakis-o-(hydroxyl). The most toxic components in the heartwood were juglone (5.15%) and 2,7-dimethylphenanthrene (5.81%).
