摘　　要：以草果果实为原料,挥发油提油率为指标,研究超临界CO_2萃取草果挥发油的分离工艺,优选的萃取工艺为:温度为60℃,压力为30 MPa,CO_2流量为25 g/min,萃取时间为120 min,此条件下提油率为5.4%。采用气相色谱-质谱(GC-MS)联用技术对挥发油进行成分分析,其主要成分为桉叶油素、(E)-2-癸烯醛、丙位十二内酯、4-丙基苯甲醛、2-十二烯醛等,并首次从草果果实中分离出丙位十二内酯、亚油酸乙酯、可可醛等8种化合物。The volatile oil is extracted from tsaoko through supercritical fluid CO2 extraction with oil extraction rate as the main indicator. The extraction yield can reach 5.4% under the following conditions： 60℃ of extraction temperature,25 g/min of CO2 flow rate,30 MPa of pressure and 120 minutes of extraction duration. The components of the volatile oil are then analyzed by GC-MS. Its main components are 1,8-cineole, （ E）-2-decenal, geranyLacetate,4- propylbenzal dehyde, etc. Among them, eight compounds, including γ-dodecalactone, ethyl linoleate, isodihydrolavandulal, and so on, are separated from the Tsaoko for the first time.
