Sažetak
The orange peel (Citrus sinensis L.) from the variety Washington Navel was extracted by supercritical CO2 at different parameters. The extracts were analyzed by GC-MS and HPLC. Limonene predominance was found (up to 89%). The principal oxygenated monoterpenes were linalool, α- terpineol, decanal, and (E)- citral. From remaining solid residue (after SC-CO2 extraction) ultrasoundassisted extraction was performed to obtain the extracts rich in hesperidin. The influence of different extraction parameters on hesperidin content (3.3 to 23.0 μg/mL) was determined. The prediction performance in optimizing the extraction yield of dominant compounds was studied by response surface methodology and artificial neural network.
