The volatile composition of the leaves of Bursera velutina Bullock (Burseraceae) was determined by a gas chromatographmass spectrometer (GCMS). the major component found was 2phenylethanol (29.5%). This is the first report of 2phenylethanol in the leaves of a species of the genus Bursera. in addition, B. velutina also produces monoterpenes, sesquiterpenes, diterpenes and alkanes, making it a species with one of the most complex chemical compositions in the genus. this diverse and unique blend of compounds may play an important role in plant defense against its herbivores.
