摘　　要：以苯甲醛、肉桂醛、苯丙醛、乙酸肉桂酯、邻甲氧基肉桂醛的提取率和含量为指标,通过单因素实验,探索粒度、提取时间、蒸馏温度等对水蒸气蒸馏提取桂叶精油的影响,并得出该5种组分的提取变化规律。进一步通过正交实验,以肉桂醛的提取率和含量分布为指标,优化了水蒸气提取肉桂有效成分的工艺条件:原料粒径20目,提取时间1.5 h,提取温度168℃,在该条件下肉桂醛的提取率和含量分别达到2.08%和91.50%。重复性实验的结论指出,该工艺所得的肉桂油品质良好,实验的重现性好。The aim of this study was to optimize the operating conditions to extract benzaldehyde, cinnamaldehyde, phenylpropyl aldehyde, cinnamyl acetate, and o-methoxy cinnamic aldehyde from cinnamon oil by steam distillation. A single factor experiment was conducted to investigate the influence of three main factors, including particle size, temperature, and time, on the yield and content of the ingredients. To explore the relationship between factors influencing yield and content of the ingredients, the operating conditions were further optimized using the orthogonal experiment with yield and content of cinnamaldehyde as criteria. The optimized parameters of the extracting processes were as follows：20 mesh,temperature 168 ℃, and time 1.5 h. The optimized process can give a yield of 2. 08% with 91.50% content of cinnamaldehyde. The repeated experiments also indicate that the same results were obtained with good quality of the target product on the basis of the optimized parameters.
