摘　　要：为有效提取雪梨籽中的油脂,采用超临界CO2萃取技术萃取雪梨籽油,研究超临界CO2萃取雪梨籽油的萃取工艺;考察了压力、温度、时间和CO2流量对油脂得率的影响,并将提取的油脂采用GC-MS进行分析,结果表明:最佳提取条件为:压力35 MPa、温度35℃、时间130 min、CO2流量15 kg/h,其油脂得率为23.9%。油脂中主要含有7种脂肪酸成分。To efficient extraction of oil from pear seed. Supercritical CO2 technology was used to extraction of oil from pear seed, The effects of pressure, temperature, time and CO2 flow rate on yields were studied. The composition of pear seed oil was analysis by GC-MS.The result showed that the best extraction conditions are：extraction pressure 35 MPa, extraction temperature 35℃, extraction time 130 min and CO2 flow rate 15 kg/h. The yield of oil was 23.9%. Total 7 kinds fatty acid were found in oil.
