摘　　要：利用自制的1 L亚临界水提取装置,进行肉桂精油的亚临界水提取研究。考察了提取条件对肉桂精油提取的影响,并采用响应面试验优化设计方法,得到肉桂精油的亚临界水提取最佳工艺:原料粒径0.3 mm,装料量175 g,提取温度132℃,提取时间38 min,压力5 MPa,此条件下肉桂精油提取得率1.83%,肉桂醛得率为1.1521%(11.521 mg/g);与传统水蒸气蒸馏法相比,提取时间相当于水蒸气蒸馏法的1/6,肉桂精油得率提高了15.8%,肉桂醛得率提高了28.4%。Subcritical water extraction （ SWE） of essential oil from cinnamon was studied by self-made apparatus. Effects of different extraction conditions on the extraction yield of cinnamon essential oil were investigated. The optimal conditions of extraction of cinnamon essential oil with subcritical water were established by response surface methodology. They were material mass 175 g, material size 0. 3 mm, temperature 132 ℃, extraction time 38 min and pressure 5 MPa. Under the above conditions, the extraction yield of cinnamon oil was 1. 83 %, and the yield of cinnamaldehyde was 1. 152 1 %. Compared with the conventional steam distillation （ SD） , the extraction time by SWE was a sixth of that by steam distillation, but the extraction yield of cinnamon oil increased 15. 8%, and the yield of cinnamaldehyde increased 28. 4 %.
