摘　　要：利用超临界CO2萃取技术从光萼小蜡花中提取精油,通过单因素实验探讨萃取压力和萃取温度对萃取产率的影响,并采用GC-MS技术对萃取物成分进行分析,发现其主要组分为苯乙醇.通过对各组萃取精油中苯乙醇含量进行比较,初步确立利用超临界CO2萃取光萼小蜡花精油的最佳工艺参数为:萃取压力25 MPa,萃取温度55℃.Volatile oil from the flowers of ligustrum sinense var. mysianthum was extracted by supercritical carbon dioxide and analyzed by gas chromatograph-mass spectrometer （GC - MS）. The major component of volatile oil was determined to be phenylethyl. The factors affecting extraction yield such as pressure and temperature were discussed. The results showed that the optimal extraction parameters were 25 MPa and 55 ℃.
