新疆莴苣子挥发油成分气相色谱质谱法分析

Analysis of Essential Oil Extracted from Lactuca sativa Seeds Growing in Xinjiang by GC-MS

目的:分析新疆莴苣子中挥发油成分。方法:采用水蒸气蒸馏法提取新疆莴苣子挥发油,运用气相色谱-质谱联用技术(GC-MS)进行分析鉴定。结果:共分离出71种成分,确认了其中62种成分,占挥发油总离子流的95.07%,其中主要成分为正己醇(36.31%)、正己醛(13.71%)、反式-2-辛烯-1-醇(8.09%)和2-正戊基呋喃(4.41%)。结论:该结果为新疆莴苣子资源的开发利用提供了理论依据。

Objective： To analyze the components of essential oil from Lactuca sativa seeds growing in Xinjiang.Methods： The components of essential oil from Lactuca sativa seeds were analyzed by gas chromatography-mass spectrometry（GC-MS）.Results： 62 components were identified from 71 separated peaks,amounting to total mass fraction 95.07%.The dominant compounds were n-Hexanol（36.31%）,n-Hexanal（13.71%）,trans-2-Octen-1-ol（8.09%） and 2-n-Pentylfuran（4.41%）.Conclusion： The research provides a theoretical basis for the exploitation and use of Lactuca sativa seeds resource.
