摘　　要：运用超临界CO2萃取技术提取红树莓籽精油,采用正交试验研究萃取温度、萃取压力、萃取时间等因素对红树莓籽精油萃取率的影响,以提取率为主要标准,确定最佳工艺条件。结果表明:萃取温度45℃,萃取压力30 MPa,萃取时间80 min为最佳提取工艺。挥发油产品透明、橙黄。通过GC-MS分析,鉴定出40种主要成分。Supercritical fluid CO2 extraction was applied to extract red raspberry seed oil.Orthogonal designing was used to study the influence of extracting temperature,extracting pressure,and extracting time on the extracting ratio of red raspberry seed oil.The technological conditions were optimized by using extracting ratio as the main standard and the optimal extracting parameters were as follows： extracting temperature at 45 ℃,pressure at 30 MPa and time at 80 min.The essential oil appears to be transparent in orange color and in which,40 kinds of main components were identified by GC-MS analysis.
