Comparison of supercritical fluid and solvent extraction methods in extracting gamma-oryzanol from rice bran

Organic solvents were compared with supercritical CO2 relative to efficiency for extracting lipid and γ‐oryzanol from rice bran. A solvent mixture with 50% hexane and 50% isopropanol (vol/vol) at a temperature of 60°C for 45–60 min produced the highest yield (1.68 mg/g of rice bran) of γ‐oryzanol am...

Zusammenfassung:Organic solvents were compared with supercritical CO2 relative to efficiency for extracting lipid and γ‐oryzanol from rice bran. A solvent mixture with 50% hexane and 50% isopropanol (vol/vol) at a temperature of 60°C for 45–60 min produced the highest yield (1.68 mg/g of rice bran) of γ‐oryzanol among organic solvents tested. The yield of γ‐oryzanol without saponification was approximately two times higher (P
