HS-SPME-GC/MS分析鸡矢藤挥发性成分

Analysis of Volatile Constituents in Paederia scandens by HS-SPME-GC/MS

目的:分析鸡矢藤的挥发性成分。方法:采用顶空固相微萃取和气质联用技术(HS-SPME-GC/MS),结合保留指数法并用峰面积归一化法测定相对含量。结果:从鸡矢藤中鉴定出了18个挥发性成分,占总峰面积的95.28%,其中百里香酚(30.97%),二甲基二硫(9.78%),喹啉(5.74%),十六酸(5.53%),邻苯二甲酸二丁酯(5.07%),邻苯二甲酸二甲酯(3.67%),壬醛(3.65%)和邻苯二甲酸二异丁酯(3.18%)等的含量较高。结论:鸡矢藤的主要挥发性成分为百里香酚和邻苯二甲酸酯类。

Objective： To assay the volatile constituents of Paederia scandens. Method： The volatiles were analyzed by head-space solid micro-extraction,coupled with GC / MS and Kovats index. Result： There were18 kinds of volatile constituents in P. scandens,95. 28% of the total essential constituents. The contents of thymol（ 30. 97%）,dimethyl disulfide（ 9. 78%）, quinoline（ 5. 74%）,n-hexadecanoic acid（ 5. 53%）,dibutyl phthalate（ 5. 07%）,dimethyl phthalate（ 3. 67%）,nonanal（ 3. 65%）,and diisobutyl phthalate（ 3. 18%） were higher. Conclusion： The major volatile constituents of P. scandens were thymol and phthalate esters.
