摘　　要：运用超声提取、回流提取、水蒸汽蒸馏、浸泡提取4种方法对缅甸产钝叶樟植物的挥发油进行了提取,通过气质联用（GC-MS）技术结合计算机检索首次分析了缅甸产钝叶樟挥发油的化学成分.分别鉴定出42、40、22、36个成分,其中黄樟素（safrole）相对含量最高,达到19.76％～28.47％.比较4种提取方法,得油率分别为3.49％、2.50％、0.85％、1.92％,表明超声提取法效果最优.The chemical constituents of volatile oil of Cinnamomum obtusifolium from Myanmar were studied.Using four methods （ultrasonic,reflux,steam distillation and immersion extraction）,the volatile oils of this plant were extracted,and the extracted rates of volatile oil were 3.49％,2.50％,0.85％ and 1.92％,respectively.The results showed that the best extraction method was the ultrasonic extraction.The chemical constituents of volatile oil were analyzed by GC-MS.In the above-mentioned four methods,42,40,22 and 36 compounds were identified respectively.The highest constituent of the essential oils was safrole（relative contents at 19.76％-28.47％）.
