The goal of this study was the obtaining of annatto seed oil fraction rich in geranylgeraniol and tocotrienols by sequential supercritical fluid extraction and to use the geranylgeraniol-rich fraction to develop emulsion-filled gels with anti-inflammatory properties by high-intensity ultrasound.

This study was primarily focused on the supercritical fluid extraction (SFE) of cherry seed oil and the optimization of the process using sequential extraction kinetics modeling and artificial neural networks (ANN). The SFE study was organized according to Box-Behnken design of experiment, with additional runs. Pressure, temperature and flow rate were chosen as independent variables. Five well known empirical kinetic models and three mass-transfer kinetics models based on the Sovová’s solution of SFE equations were successfully applied for kinetics modeling. The developed mass-transfer models exhibited better fit of experimental data, according to the calculated statistical tests (R2, SSE and AARD). The initial slope of the SFE curve was evaluated as an output variable in the ANN optimization. The obtained results suggested that it is advisable to lead SFE process at an increased pressure and CO2 flow rate with lower temperature and particle size values to reach a maximal initial slope.

A comparison of chemical composition of bay laurel extracts obtained by microwave extraction, supercritical fluid extraction and steam distillation was performed. Microwave extraction and steam distillation were shown to give similar essential oils. Microwave extract contains more monoterpenoid components, especially hydrocarbons. Steam distillation oil contains more sesquiterpenoid compounds, mostly oxygenated. SFE extract composition differs substantially from the ones obtained by two other methods. According to GC-MS data they contain much more sesquiterpenoid components, namely sesquiterpene lactones. This makes SFE a perspective candidate for isolation of biologically active compounds from laurel leaves. However, apart from valuable compound SFE extracts also contain substantial amounts of waxes as well as large quantities of some non-volatile component undetectable via GC-MS. In order to implement SFE into the practice of laurel processing one has to develop an approach for the fractionation of SFE extracts allowing isolating sesquiterpene lactone enriched fraction.
