<P><I>Hagenia abyssinica</I> and <I>Artemisia absinthium</I> are widely distributed tree species in Ethiopia and known for their traditional medicinal uses. The present study was conducted to determine the essential oil and smoke constituents of <I>H. abyssinica</I> and <I>A. absinthium</I> leaves using GC-MS. The main components of the <I>A. absinthium</I> essential oil were valencene (5.48%), bornyl acetate (5.15%), and <I>trans</I>-cinnamic acid (4.34%). 2-Bornanone (18.54%), <I>o</I>-cymene (12.80%), and nerolidol (7.04%) were the dominant components of the MeOH fraction of the smoke derived from the leaves of <I>A. absinthium</I>, while 2-propenoic acid butyl ester (46.49%), heptadecane (10.66%), and 9-octylheptadecane (7.78%) were the major components of the <I>n</I>-hexane fraction. The main components of the <I>H. abyssinica</I> essential oil were <I>cis</I>-davanone (14.73%), Aristolediene (9.31%), and cryptone (6.50%). <I>β</I>-Myrcene (12.59%), neophytadiene (11.54%), and limonene (11.27%) were the dominant components of the MeOH fraction of the smoke derived from the leaves of <I>H. abyssinica</I>. 1,3,5,7-Cyclooctatetraene (33.58%), prehnitene (7.01%), and heptadecane (5.46%) were the dominant components of the <I>n</I>-hexane fraction of the smoke derived from the leaves of <I>H. abyssinica</I>. The smoke components of <I>A. absinthium</I> and <I>H. abyssinica</I> were reported here for the first time.</P>
