摘要:以萃取压力、萃取温度、分离温度与萃取时间为参数,对紫穗槐精油超临界CO2萃取的最佳工艺条件进行了分析,并用气相色谱-质谱联用技术(GC-MS)对精油成分进行了鉴定.结果表明:萃取温度40 ℃、萃取压力25 MPa、分离温度38 ℃、萃取时间1.5 h为最佳工艺条件;精油含26种成分,占总萃取物含量的89.96%,主要包括α-蒎烯,月桂烯,α-雪松烯,β-桉叶油醇,反式-石竹烯,β-荜澄茄油烯等.

Abstract: The best techniques parameters of Supercritical Fluid Extraction of essential oil in the Fructus sphere japonica of Amorpha fruticosa,including extracting pressure,extracting temperature,separating temperature,were analyzed,and the compositions of the essential oil were identified with GC-MS technology.The result showed that:the best parameters of extraction of the Fructus sophorae japonicae of Amorpha fruticosa with SEF-CO2 were extracting temperature 40 ℃,extracting pressure 25 MPa,separating temperature 38 ℃ and extracting time 1.5 h;26 kinds of compositions were identified (occupied 89.96% of all extractions),mainly including a-Pinene,Mreene,a-Cedrene,β-Eudesmol,Trans-Caryophyllene,β-Cubebene and so on.

Key words: supercritical Fluid-CO2 extraction, amorpha fruticosa, essential oil, GC-MS
