Essential oils extracted from Schinus molle L. and Schinus terebinthifolius Raddi, Anacardiaceae, leaves and fruit hydrodistillation, as well as, their chemical composition and extraction kinetic were evaluated. For this proposal, 6 h extraction and aliquots collected at sequencing different times (0.5, 1, 2, 4 and 6 h) were carried out allowing calculating accumulated content (% w/w) and verifying essential oil chemical profile. β-caryophyllene (35.2%), α-pinene (28.1%) and germacrene D (15.5%) represent S. terebinthifolius dried leaves essential oil major components, as well as, α-pinene (44.9%), germacrene D (17.6%) and β-pinene (15.1%) in the fruit. Cubenol (27.1%), caryophyllene oxide (15.3%) and spathulenol (12.4%) represent S. molle dried leaves essential oil major components, and β-pinene (36.3%) α-pinene (20.3%), germacrene D (12.1%) and spathulenol in the fruit. Essential oil extraction kinetics showed a hyperbolic distribution; monoterpene content presented exponential decay in time function and sesquiterpene showed exponential growth. Faster monoterpene extraction than the sesquiterpene extraction was observed, however, both presented increasing exponential distribution.
