摘　　要：以杜香为原料,采用水、乙醇复合溶剂直接提取杜香挥发油。通过复合溶剂浸提法以单因素试验和正交试验研究提取温度、提取时间、料液比等因素对杜香挥发油提取的影响。结果表明,提取温度、料液比、溶剂配比是关键因子,提取时间、萃取次数等影响较小。试验表明,在浸提温度20℃条件下,提取时间1.5 h,料液比1∶10,乙醇与水的配比为3∶2时,石油醚60 m L条件下,杜香油提取量最大为24.9 mg/g。This study investigated extraction method of oil from Ledum palustre L.,the volatile oil of Ledum palustre L. was extracted directly by water and ethanol. The effects of factors such as temperature, time and night ratio on the extraction of volatile oil of Ledum palustre L. were studied by single factor experiment and orthogonal experiment by compound solvent extraction. The results showed that the extraction temperature,the ratio of material to liquid and the ratio of solvent were the key factors, and the extraction time and the number of extraction times had little influence on the extraction. The experiment proved that the extraction of 1.5 h at 20 ℃, the ratio of liquid to material was 1 ∶10, ethanol ∶water was 3 ∶2, and petroleum ether 60 mL,the extraction amount of duer oil was 24.9 mg/g.
