摘　　要：由于超临界CO2萃取所得的玫瑰粗油含蜡质较高，影响品质，故采用无毒、无害、高效的分子蒸馏技术对其进行脱蜡，避免了传统有机溶剂法对精油品质的破坏，精油得率可达20．6％。正交试验表明分子蒸馏法提纯玫瑰精油最佳工艺条件：蒸馏压力3．0Pa，蒸馏温度110℃，物料流量2.0mL·min^-1，刮膜转速480r·min^-1。Rose oil extracted with supercritical CO2 fluid extraction has much more waxes which has affected its quality. The rose oil was refined with molecular distillation,which is non-toxic, innocuous and high-efficient, and also avoids being destroyed by the traditional organic solvent method. Yield of refined rose oil reached 20.6%. The results showed that the optimal refining conditions were determined with distillation pressure 3.0 Pa, distillation temperature 110℃, feeding rate of rose oil 2.0 mL ·min^-1 and agitating speed 480 r·min-1.
