摘　　要：研究萃取温度、萃取压力、萃取时间对超临界CO_2萃取罗勒子油得率的影响,进行了工艺的优化。结果表明,影响超临界CO_2萃取罗勒子油得率的因素主次顺序为A(压力)>C(时间)>B(温度),最佳工艺条件为萃取压力300 Pa,萃取温度45℃、萃取时间为3 h。在此工艺条件下,罗勒子油得率为17.05%。罗勒子油脂肪酸组成主要为亚麻酸(85.76%)、棕榈酸(8.54%)和硬脂酸(5.1%),其中不饱和脂肪酸含量为86.35%。The studies on the optimum conditions for the extraction of basil seeds oil by supercritical CO2 fluid were carried out. The primary and secondary effect factors on the extraction of basil seeds oil by supercritical CO2 fluid were as followed：pressure〉 time 〉temperature. The optimum conditions were ：extraction pressure300 Pa,extraction temperature 45 ℃,extraction time 3 hours. Under these conditions,the maximum extraction rate was 17.05 %.The fatty acid composition of basil seeds oil was mainly composed of linolenic acid（85.76 %）,palmitic acid（8.54 %）and stearate（5.1 %）,in which the content of unsaturated fatty acids reached 86.35 %.
