阿育魏实挥发油成分的GC-MS研究

Study on the Volatile Oil of Trachyspermum ammi (L.) Sprague by GC-MS Method

目的:搞清维吾尔族药材阿育魏实的挥发油中的主要化学成分。方法:采用水蒸气蒸馏法制备阿育魏实挥发油,用气相色谱-质谱联用技术对阿育魏实的挥发油成分进行研究。结果:阿育魏实挥发油的总收率为7.8%,从中共鉴定出8个化合物,其相对含量之和占挥发油总量的99.99%,其中主要成分为麝香草酚(Thymol,57.45%),1-Methyl-2-(1-methylethyl)benzen(e16.72%),2.6.6-Trimethyl-bicyclo[3.1.1]hept-2-en(e23.69%)。结论:该研究提供了一种阿育魏实挥发油成分的分析方法,并且发现阿育魏实可作为麝香草酚的重要资源植物。

Objective： To study the volatile oil of Trachyspermum arnmi （L.） Sprague. Methods： The constituents were identified by GC-MS method. Results： A total of 8 compounds were identified, occupying 99.99% of the total volatile oil. The main compounds including 1-Methyl-2-（1-methylethyl）benzene（16.72%）, 2.6.6-Trimethylbicyclo[3.1.1 ]hept-2-ene（23.69%）, Thymol（57.45%）. Conclusion： This method can be used for analysis of the volatile oil of T. ammi. The high content of Thymol （57.45%） suggest that T. Ammi. can be used as the sources of the Thymol.
