金佛手挥发油化学成分的GC-MS分析

Analysis of chemical composition of volatile oils from Citrus Bergamot by GC - MS

目的:分析金佛手鲜品与干品挥发油的化学成分与相对含量。方法:用色谱-质谱联用法(GC-MS)测定佛手挥发油,结果用计算机检索NIST98数据库。结果:从佛手挥发油中检测出30多种化学成分,主要成分是D-柠檬烯和(+)-2-蒈烯,鲜品挥发油中分别为40.02％、21.35％,干品挥发油中分别为38.63％、18.17％。结论:金佛手挥发油的主要成分是柠檬烯与蒈烯。

Objective: To analyse the chemical compositions and their relative content of volatile oils from fresh and dried Citrus Bergamot. Methods: The microanalytical technique combining Gas Chromatography and Mass Spectrometry(GC-MS) was used for the qualitative as well as quantitative determinations of compounds from the Bergamot volatile oils . The results was compared with NIST98MS database by computer. Results: More than 30 kinds of chemical composition were obtained from Bergamot volatile oils. Among them the majority were D-Limonene and (+)-2-Carene. Their relative content was 40. 02%,21. 35% in fresh Bergamot volatile oils and 38. 63% ,18. 17% from dried Bergamot. Conclusion:The majority chemical composition in Citrus Bergamot volatile oils were Limonene and Carene.
