山苍子油是一种重要的调味品和香料，在食品和化妆品领域具有良好的应用前景。本文采用水蒸气蒸馏法（SD）提取山苍子油，采用GC—MS分析了其化学成分，建立了提取山苍子油的动力学模型，对强化提取过程进行了分析。提取山苍子油的适宜工艺条件为：液料比20：1，提取时间4h，得率为3．06％。GC—MS鉴定了26种化合物的结构，山苍子油的主要成分是香叶醛（17．94％），橙花醛（14．58％），柠檬烯（9．25％），芳樟醇（8．44％），桉树脑（7．11％）和α-松油醇（5．74％）。山苍子油中柠檬醛（两种异构体香叶醛和橙花醛）的含量为32．52％。SD法提取山苍子油的动力学模型为V．=0．87081（1-e^-0....

Litsea Cubeba oil is an important condiment and perfume andwidely used in food and cosmetics industry. Lit- sea Cubeba oil extracted by steam distillation（ SD ） was analyzed by GC - MS. Extraction kinetics model of Litsea Cubeba oil was established, and optimized extraction process was analyzed. The yield of Litsea Cubeba oil was 3.06% under the optimized conditions of solid ： liquid ration of 20 ： 1 and extraction time 4.0 h. Twenty six compounds were identi- fied in Litsea Cubeba oil by GC - MS, and its major components were geranial（ 17...
