摘　　要：【目的】探究不同因素对柳叶蜡梅茶精油提取率的影响,为今后柳叶蜡梅茶精油提取及进一步综合开发利用奠定理论基础。【方法】以阴干后的柳叶蜡梅碎叶片为原料,采用水蒸气蒸馏法提取柳叶蜡梅茶精油,以精油提取率为评价指标,通过单因素实验考察提取过程中蒸馏时间(min)、料液比(g·mL^(-1))与NaCl质量浓度(%)3个因素对柳叶蜡梅茶精油提取率的影响,并采用正交试验进一步优化柳叶蜡梅茶精油提取工艺,从而确定最佳的提取条件以及在该方案下柳叶蜡梅茶精油的提取率。【结果】柳叶蜡梅茶精油的最佳提取条件为:料液比为1∶2(g·mL^(-1)),NaCl质量浓度为2%,在380℃条件下用水蒸气蒸馏150 min,此时柳叶蜡梅茶精油的提取率达到最高,为2.122%。3个因素对柳叶蜡梅茶精油提取率的影响主次顺序为料液比>蒸馏时间>NaCl质量浓度。【结论】采用正交试验优化得到的柳叶蜡梅茶精油提取工艺条件可靠,可为柳叶蜡梅茶精油的提取方法提供参考。【Objective】Extraction of essential oil from Chimonanthus salicifolius was optimized in preparation for mass production to promote the medicinal utilization of the plant material.【Method】Effects of varied processing conditions on the extraction of essential oil from dried C.salicifolius leaves were determined.Optimal extraction conditions to maximize yield of a steam distillation process,including distillation time,solid-liquid ratio,and NaCl concentration,were analyzed by using a single-factor test followed by an orthogonal experimentation.【Result】The optimized extraction was conducted with a solid-liquid ratio of 1∶2(g·mL^(-1))at the NaCl concentration of 2%and steam-distilled at 380°C for 150 min to arrive at a 2.122%essential oil extraction rate.The main factors affecting the extraction efficiency ranked as solid-liquid ratio>distillation time>NaCl concentration.【Conclusion】The C.salicifolius essential oil extraction from dried leaves of the plants was successfully optimized for the processing technology development.
