摘　　要：目的:研究紫玉盘茎挥发油的化学成分。方法:采用超临界CO2萃取法提取紫玉盘茎挥发油,用气相色谱-质谱联用技术对其化学成分进行分离鉴定。结果:从紫玉盘茎挥发油中共分离出68个色谱峰,鉴定其中37个化合物,占总量的85.73%,主要成分有苯甲酸、8-氧代-9H-环异长叶烯、对甲氧基桂皮酸乙酯。结论:超临界CO2萃取法提取挥发油与水蒸气蒸馏法提取挥发油的化学成分有明显的差异。Objective：To study the chemical constituents of the essential oils from stem of Uvria microcarpa Method： The essential oils were extracted by supercritical carbon dioxide extraction（SFE-CO2）,and then the constituents were separated and identified by GC-MS.Result： Six-eight compounds were isolated and 37 compounds were identified,that composed about 85.73% of the total essential oils,the principal chemical constituents of the essential oils are benzoic acid,8-oxo-9H-cycloisolongifolene,3-（4-methoxyphenyl）-2-propenoic acid ethyl ester.Conclusion： There are some differences in the principal chemical constituents and content of the essential oil extracted by SFE and SD.
