摘　　要：目的:研究果上叶中的挥发性成分。方法:利用有机溶剂-水蒸气蒸馏法提取果上叶挥发油,用GC-MS进行测定,结合计算机检索技术对分离化合物进行结构鉴定,应用色谱峰面积归一化法计算各成分的相对百分含量。结果:分离鉴定出38种化学成分,占挥发油总量91.448%,其中含量大于2%的分别为Z-9-十八烯醛18.075%、2,4-二叔丁基苯酚3.264%、棕榈酸5.413%、油酸25.079%、二十三烷6.344%、二十四烷3.768%、1-十八烯酸单甘油酯2.146%、亚油酸甘油酯4.953%、二十五烷4.332%、二十六烷3.387%、二十七烷3.841%、二十八烷3.102%。结论:本文采用气相色谱-质谱联用法对果上叶中的挥发性成分进行研究。Objective：To study the chemical constituents of the volatile oil from Bulbophyllum odoratissium. Method： The chemical compositions of the volatile oil of the plants which were obtained by organic-steam distillation with hexane were analyzed by GC-MS. The constituents were identified by their mass spectra. The relative percentage of the oil constituents was calculated from the GC peak areas. Result： Thirty-eight kinds of chemical components were identified from B. odoratissimum. The amount of the identified components was accounted for 91. 448% of all the volatile oil. The constituents whose relative content was more than 2% were determined as Z-9- octadecenal （18. 075% ）, 2,4-Di-tertbutylphenol （3. 264% ）, palmitic acid （5.413%）, oleic acid （25. 079% ）, tricosane （6. 344% ）, tetracosane （3. 768 % ）, 1-Monoolein （2. 416% ）, 1-monolinolein （4. 953 % ）, pontacosane （4. 332% ）, hexacosane （3. 387% ）, heptacosane （3. 841% ）, octacosane （3. 102% ）. Conclusion： The composition of volatile oils from B. odoratissirnum by GC-MS.
