Sažetak
Rose hip (Rosa canina L.) and Cornelian cherry (Cornus mas L.) seeds are a waste product from the manufacture of juice, syrup, puree, jams, or wines, and contain a significant amount of oil. Rose hip seed oil has an effect on improving lipid metabolism, a possible anticancer effect, and a positive effect on skin diseases, including dermatoses, ulcers, and the effects of skin aging. Cornelian cherry seed oil shows the possibility for recovery and regeneration of external and internal epidermal tissues and possesses significant antimicrobial activity. Special emphasis in the last few decades has been given to the “green” supercritical CO2 extraction technique, which is environmentally friendly and enables better extraction yield, better quality of the extract, and resource saving. The aim of this study was to investigate the influence of different extraction parameters, pressure (119-331 bar), and temperature (36-64 °C) on: (1) oil yield, (2) peroxide value, (3) determining the optimal extraction conditions by response surface methodology (RSM), using Central Composite Rotatable Design (CCRD). The fatty acid composition was determined by gas chromatography and mass spectrometry (GC-MS). The oil yield of rose hip seeds varied between 3.26-7.75 %, in the cornelian cherry seeds it was between 2.35-5.18 %, and the peroxide values varied between 4.70-29.69 % and 0.55-7.36 mmol O2/kg, respectively, depending on the applied extraction conditions.
