| Summary: | <p class="Default">This study aimed at determining the chemical composition and evaluating the influence of different times of hydrodistillation on the content of essential oil from <em>Eugenia pyriformis</em> (Myrtaceae) leaves. Four extraction times (60, 120, 180 and 240 minutes) were investigated by a completely randomized experimental design. The highest yield of oil was achieved in the 120-minute hydrodistillation time. The main compounds of the oil determined by GC-MS analyses were β-caryophyllene (18.0%), bicyclogermacrene (16.4%), spathulenol (10.0%) and α-cadinol (8.7%).</p><p class="Default"> </p><p class="Default">DOI: <a href="http://dx.doi.org/10.17807/orbital.v11i5.1221">http://dx.doi.org/10.17807/orbital.v11i5.1221</a></p><p class="Default"> </p>
