“…The total sterols of FMBO amounted to1.55% by SFE and 1.09% by SE, which indicates that FMBO by SFE can contain 1.422 times higher sterols than FMBO by SE. This result is in agreement with other previous research where the SFE were used to extract oils from plant seeds (Jiang and Niu, 2011;Shao et al, 2008). β-sitosterol was found to be the major sterol (56.26% of the total sterols by SFE), followed by campesterol and stigmastanol, at about 15.91% and 15.1%, respectively.…”

“…It was observed that the response value of the extraction rate increased with the rising of pressure when the temperature was lower than 47.5 °C; when the temperature was higher than 47.5 °C, the response value decreased. This phenomenon was in consistence with other previous reports and is explained by the fact that the increased pressure would also lead to an increase in the density of supercritical CO 2 (Jiang and Niu, 2011;Shao et al, 2008). Fig.1 (b) shows the interaction between the extraction pressure (X 1 ) and time (X 3 ) at the fixed temperature at 45 °C.…”

“…RSM has been applied in many process optimizations such as biodiesel production, adsorption processes, synthesis of oleo chemicals and catalyst development (Jiang andNiu, 2011, Ghadge andRaheman, 2006). However, there are scarce reports on the optimization of the epoxidation of oils and alkyl esters (Sun et al, 2011, Naidir et al, 2011.…”

“…The antioxidant activity of the oil was analyzed using a 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging assay according to the method described by Jiang et al (2011) with some modifications. A stock solution of DPPH (200 μmol·L −1 ) was prepared in methanol and kept cold and in the dark until use.…”
