欧亚旋覆花挥发油的GC-MS分析

Study of Chemical Constituents of the Essential Oil from Inula britannica L.by GC-MS

用GC-MS对山西运城地区产欧亚旋覆花挥发油进行化学成分分析。鉴定了欧亚旋覆花挥发油中的62个成分,约占挥发油总成分的68.4%。主要成分为2,3,4,5四氢1苯并庚英3醇(相对含量4.276%)。

Objective:The chemical components of the essential oil from Inula britannica L.,which were collected from Yuncheng area of Shanxi province, were analyzed by GC-MS.Methods:The essential oil was extracted from Inula britannica L.by steam distillation,the components were separated with the capillary chromatographic columns,the amount of the components from the essential oil was determined by normalization method.The components separated were identified by data search system.The chromatographic conditions were as follows:DB-5 (30m×0.25mm,0.25μm) capillary column;High purity helium was used as carrier gas,and the flow rate was 1.0ml/min;Column temperature:70℃ keeping 2min,from 70℃ to 230℃ at rising rate 10℃/min and keeping 10min;Split ratio 15∶[KG-*2]1 ;Injector temperature 250℃.Results:62 peaks were identified representing 68.4% of the total contents.Main component was 1-Benzoxepin-3-ol,2,3,4,5-tetrahydro-(4.276%).Conclusion:The method is so reliable,stable,and good reproducible that can be applied to the analysis of the essential oil from Inula britannica L.
