GC/MS法分析花椒挥发油的化学成分

Analysis of Chemical Component of Volatile Oil From Zanthoxylum Bungeanum Maxin by GC/MS

用水蒸气蒸馏法对岳阳产花椒果实进行挥发成份的提取 ,测得挥发油的含量为 1 .2 %。用 GC/ MS分析法对其进行了分离、鉴定。初步分离出 60余个峰 ,鉴定出 5 2种物质 ,用面积归一法确定其相对含量。在被测物质中 ,烃类化合物有 1 8种 ,主要物质为石竹烯 (占被测组分的 (下同 ) 8.4 4% )、大根香叶烯 (2 .99% )等。有机含氧化合物 3 4种 ,主要组分为 γ-萜品醇 (1 0 .3 % )、β-萜品醇 (9.3 7% )、水芹醇 (8.78% )、石竹烯含氧化合物 (4.2 3 % )

The volatile oil is extracted from zanthoxylum bungeanum maxin using steam distillation. More than sixty kinds of peaks and fifty-two species of compounds are separated and identified by GC/MS. The relative components of these coumpounds are calculated using square peaks to normalization. Among the fifty-two species of identified compounds, there are the eighteen species of hydrocarbon compounds which are mainly caryophyllene (8.44% counted in the eighteen species of identified components)and germacreneand (2.99%) etc, and the thirty-four species of oxygenated hydrocarbon derivatives which are mainly γ-terpineol(10.3%), β-terpineol (9.37%), carveol (8.78%) and caryophyllene oxide (4.23%) etc.
