摘要： 研究了超声波辅助溶剂法萃取芦柑籽精油的最佳工艺条件，并分析其理化性质及脂肪酸组成。结果表明，采用超声波功率130W、料液比（mg︰mL）1︰7、处理时间120s，所得精油提取率为40.49%，且各理化指标均符合要求；气相色谱-质谱联用（GC-MS）分析表明芦柑籽精油含有亚油酸（36.0721%）、油酸（28.1571%）、棕榈酸（29.5704%）、硬脂酸（3.4877%）、亚麻酸（2.7126%），不饱和脂肪酸含量高达66.9418%。

Abstract: The Process Conditions for Essential oil from poon-kan seed by ultrasonic-assisted solvent were studied. The physicochemical properties and the fatty acid composition were analyzed. The results showed that the yield of essential oil was 40.49% at the conditions of 250W ultrasonic power, 1∶7 solid-liquid ratio and 120s for extraction, and the physicochemical indexes of essential oil meet the requirement. Analysis of gas chromatography-mass spectrometry (GC-MS) showed that essential oil from poon-kan seed including Linoleic Acid (36.0721%), oleic acid (28.1571%), palmitic acid (29.5704%), stearic acid (3.4877%), linolenic acid (2.71%), and unsaturated fat was 66.9418%.
