摘　　要：对杜仲籽油提取的较优方法和该法下的最佳提取条件进行了研究,为杜仲籽油的综合开发利用提供理论依据。对超声波萃取法、索氏抽提法和溶剂浸泡法提取杜仲籽油的方法进行了比较,并研究了提取杜仲籽油的最佳方法及最优条件。确定杜仲籽油的最佳提取方法和最优提取条件。结果表明,杜仲籽油提取的最佳方法为索氏抽提法,最佳条件为:以石油醚为提取剂,料液比1︰10(g/mL),于55℃条件下提取2 h。此条件下杜仲籽油的提取率可达97.44%。Provide the theory basis for comprehensive exploitation and utilization ofEucommia ulmoides seed oil. The comparative study of the ulwasonic wave extraction, soxhlet extraction and solvent immersion method to extract eucommia seed oil was carried out. The extraction and the optimal condition of eucommia seed oil were studied. Results show that the best way to extract Eucommia ulmoides seed oil is soxhlet extraction. The optimal condition was that the petroleum ether as extraction agent, the solid-liquid ratio of 1 ： 10 （g/mL）, extracting at 55 ℃ for 2 h. The Eucommia ulmoides seed oil extraction yield is 97.44%.
