Carbon dioxide extraction of ginseng root hair oil and ginsenosides

Effects of supercritical carbon dioxide extraction conditions on yields and antioxidant activity of Chlorella pyrenoidosa extracts

“…The enhancement of yields of extracts, due to the effect of modifier, may be the result of physical interaction of solutes with the mixed solvent, possibly owing to an increase in the solvent density Table 2 Results obtained at the experimental condition using L 16 (4 5 ) orthogonal design (%) 1 I IV II III IV 7.78 2 I III I I I 2.15 3 I II IV II III 3.97 4 I I III IV II 4.95 5 II IV I II II 3.25 6 II III II IV III 3.50 7 II II III III I 3.31 8 II I IV I IV 2.49 9 III IV IV IV I (Palmer & Ting, 1995). This result was in agreement with the previous studies that modifier increased the yield of ginseng oil and the effect was dose-dependent (Wang, Chen, & Chang, 2001).…”

Optimization of Extraction Condition for Supercritical Carbon Dioxide (SCCO 2) Extraction of Strobhilantes crispus (Pecah Kaca) Leaves by Response Surface Methodology

“…The enhancement of yields of extracts, due to the effect of co-solvent, may be the result of physical interaction of solutes with the mixed solvent, possibly owing to an increase in the solvent density [20]. This result was in agreement with the previous studies that modifier increased the yield of ginseng oil and the effect was dose-dependent [21].…”

Co-solvent Selection for Supercritical Fluid Extraction of Astaxanthin and Other Carotenoids from Penaeus monodon Waste

“…However, the addition of polar entrainers could increase the solubility of a less soluble solute in the solvent mixture, which in turn improves the extraction efficiency. The enhancement in solubility is possibly due to the increase of solvent density, polarity as well as the specific chemical interactions like hydrogen bonding 32 . In this study, the ethanol helped to swell the pores of the biomass, which in turn improved the interaction of the SC-CO 2 with the cell.…”
