ABSTRACT
AbstractEssential 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.
