利用超声波从火棘籽中提取火棘籽油，此法有良好的提取率。正交试验考察了超声波功率、提取时间、料液比以及提取温度对提取率的影响，得出最佳提取条件为超声波功率250 W，提取时间40 min，提取温度45℃，料液比1∶8（g∶mL），在此条件下火棘籽油的提取率为7.66%。%Pyracantha fortuneana see d oil was extracted by ultrasound and this method led to high extraction yield. The ultrasonic power,the effect of the extraction time,the solid/solvent ratio and the extraction temperature to the extraction rate were examined by the orthogonal experimental.The optimized conditions were found as follows:the ultrasonic power was 250 W,the extraction time was 40 min,the extraction temperature was 45℃,the solid/solvent ratio was 1∶8(g∶mL).On this condition the extraction yield of Pyracantha fortuneana seed oil reached 7.66%.
