20.500.12556/RUL-165396 Supercritical CO$_2$ extraction vs. hexane extraction and cold pressing comparative analysis of seed oils from six plant species Supercritical fluid extraction using carbon dioxide (SFE-CO$_2$) brings a convincing advance in the production of plant oils used in cosmetics, in fortified foods and dietary supplements, and in pharmaceuticals and medicine. The SFE-CO$_2$-extracted, hexane-extracted, and cold-pressed plant oils of pumpkin (Cucurbita pepo L.), flax (Linum usitatissimum L.), linden (Tilia sp.), poppy (Papaver somniferum L.), apricot (Prunus armeniaca L.), and marigold (Calendula officinalis L.) seeds were investigated in terms of oil yield, fatty acid composition, unsaponifiable matter yield and composition, and the antioxidant activity of unsaponifiable matter. SFE-CO$_2$ proved to be the preferred extraction method for four out of six plant materials, especially for seeds with lower oil content. However, for seeds with higher oil content, such as apricots, cold pressing is a viable alternative. A comparison of fatty acid composition did not reveal significant differences between extraction techniques. SFE-CO$_2$ extraction improved the total phytosterol content of oils, especially pumpkin seed oil. A high variability in the antioxidant potential of the unsaponifiable matter studied was determined, with pumpkin seed oil showing the highest antioxidant activity. A correlation analysis was performed between unsaponifiable composition and antioxidant activity, and showed statistically significant correlations with squalene, cycloartenol, and an unidentified compound. This is the first comparison of the phytosterol compositions of linseed, apricot, linden, and marigold. Through continued optimization, SFE-CO$_2$ has the potential to revolutionize the production of plant oils and provide a sustainable and efficient alternative. cold pressing CO$_2$ extraction solvent extraction plant seed oils unsaponifiable matter hladno stiskanje ekstrakcija CO$_2$ ekstrakcija s topilom olja rastlinskih semen neumiljive snovi ekstrakcija true false true Angleški jezik Slovenski jezik Članek v reviji 2024-12-05 09:21:48 2024-12-05 09:22:01 2025-11-24 15:08:49 0000-00-00 00:00:00 2024 0 0 18 str. iss. 23, art. 3409 Vol. 13 Dec. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 66.061.3:664.34 2223-7747 10.3390/plants13233409 217733635 plants-13-03409.pdf plants-13-03409.pdf 1 0C46A581164F3964F2E902CC1BB08E65 ac70611904ef42c86102647dd7ee15616c3c5debfd8dfd691ae5523de1d51230 f9aadcaa-b2e1-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=196526 https://www.mdpi.com/2223-7747/13/23/3409 1 8e85bff3-b2e1-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=196525 Fakulteta za farmacijo 0 0 0
