The volatile components of hickory wood tar were fractionated by preparative gas chromatography. Individual fractions were analyzed on a Carbowax 20M 50 ft x 0.02 in. support coated open tubular column (SCOT) coupled to a mass spectrometer.The following compounds are among those being reported for the first time from hickory wood tar: 2-methyl-2-butenoic acid; benzaldehyde; 2-ace-tylfuran; 2-cyclohexenone; 4-propylguaiacol; 4methylveratrol;3-methyl-2-cyclopenten-l-one; 2,3-pentanedione; acetophenone; resorcinol;vinylphenol; 2,6-dimethylphenol; and 2-ethylphenol. A total of six aldehydes, eight ketones, four esters, six furans, 12 aromatic hydrocarbons, 32 phenols, and 13 acids were identified.
