摘  要：
采用四元二次通用旋转设计研究了裸大麦中生育三烯酚的超临界CO2流体萃取工艺。结果表明:萃取温度对生育三烯酚提取率有显著影响,乙醇添加量和萃取时间对生育三烯酚提取率有极显著影响,而萃取压力对生育三烯酚提取率无显著影响,但萃取压力和乙醇添加量的交互项对生育三烯酚提取率有显著影响;在本实验条件下,生育三烯酚最佳超临界CO2萃取条件为:萃取温度51.8℃、萃取压力34.7MPa、乙醇添加量9%、萃取时间120min。

摘  要：
The supercritical CO_2 extraction of tocotrienols from hulless-barley was researched. The effects of temperature, pressure, ethanol concentration and extraction time on the extracting rate of tocotrienols were discussed with quadratic perpendicularity and universal rotation regression mathematical model. Extraction temperature has a significant effect (α=(0.05)) on the extracting rate of tocotrienols, while the ethanol concentration and extraction time have a very significant effect (α=0.01) on the extracting rate of tocotrienols. The interaction between pressure and ethanol concentration has a significant effect on the extraction rate of tocotrienols, but not the extraction pressure alone. The optimum SFE-CO_2 parameters for extracting tocotrienols are the extraction temperature 51.8℃, the pressure 34.7 MPa, the ethanol concentration 9% and the extraction time 120 min.
