摘　　要：为了研究凤眼草挥发油的化学成分,本文采用超临界CO2萃取技术从凤眼草中提取挥发油,并用GC-MS法采用最佳分析条件对化学成分进行鉴定,用峰面积归一法测定各化合物在挥发油中的相对百分含量;通过研究,鉴定出42种化合物,其峰面积相对含量约占挥发油总量的92.91%。凤眼草挥发油的主要组分为邻苯二甲酸异丁辛酯(7.05%),棕榈酸(8.74%),(Z,Z)-9,12-十八碳二烯酸(20.47%),(Z)-9,17-十八碳二烯醛(15.14%),22,23-二氢豆甾醇(14.09%),3,5,6,7,8,8a-六氢-4-8a-二甲基-6-[1-甲乙烯基]-2(1H)萘酮(6.86%),α-香树脂醇(2.04%),羽扇烯酮(3.53%)等。To study the chemical consititue of the volatile oil from the seeds of Ailanthus altissima（Mill.） Swingle,the volatile oil was extracted from the seeds of Ailanthus altissima（Mill.） Swingle by Supercritical CO2 and the chemical consitituents were analyzed with the opimum separating and analyzing conditions by GC-MS,then the percentage content of composition of volatile oil were determined by peak area normalization method.Futhererly,42 compounds were separated and identified which accounted for 92.91 % of the total volatile oil.The main constituents of the oil were Phthalic acid,isobutyl octyl ester（7.05 %）,n-Hexadecanoic acid（8.74 %）,9,12-Octadecadienoic acid（Z,Z）（20.47 %）,9,17-Octadecadienal,（Z）（15.14 %）,Stigmasterol,22,23-dihydro（14.09 %）,2（1H） Naphthalenone,3,5,6,7,8,8a-hexahydro-4,8a-dimethyl-6-（1-methylethenyl）（6.86 %）,alpha.-Amyrin（2.04 %）,Lup-20（29）-en-3-one（3.53 %）.
