固相微萃取-气质联用法分析贵州产杏香兔耳风挥发性成分

目的:研究杏香兔耳风挥发油成分。方法:采用固相微萃取法从杏香兔耳风全草中提取挥发油,并用气相色谱-质谱法(GC-MS)结合保留指数法对化学成分分析鉴定,并用峰面积归一化法测定其相对质量百分含量。结果:共分鉴定出14种成分。相对含量占挥发性成分总峰面积的59.92%。结论:主要挥发性成分为(3-乙基-8-甲基-S-三唑4,3-a]吡嗪(43.37%)、石竹烯(8.89%)、Z,Z,Z-1,5,9,9-四甲基-1,4,7-环十一碳三烯(2.47%)等成分。

Analysis of Volatile Compounds from Ainsliaea Fragrans in Guizhou by SPME-GC/MS

Objective: The volatile compounds from Ainsliaea fragrans were studied. Method: Solid-phase micro-extraction(SPME) was used to extract the volatiles. The chemical constituents were analyzed by gas chromatography-mass spectrometry(GC-MS) coupled with Kovats indece. A quantitative analysis in percent was performed by peak area normalization measurements. Result: Fourteen compounds were identified, 59.92% of total volatiles. Conclusion: The main compounds were 3-ethyl-8-methyl-S-triazolo pyrazine(43.37%), caryophyllene(8.89%), Z,Z,Z-1,5,9,9-tetramethyl-1,4,7-cycloundecatriene(2.47%).
