摘要
采用顶空固相微萃取和气相色谱-质谱(GC-MS)联用技术对香叶天竺葵与柠檬香蜂草的精气进行分析鉴定,并用面积归一法测定其相对含量.结果显示,在香叶天竺葵和柠檬香蜂草中分别鉴定出62和43种化学成分,分别占总精气成分的99.5%和99.9%.其中,香叶天竺葵的主要成分为香叶醇(17.8%)、愈创蓝油烃(14.6%)、d-杜松烯(12.0%)、香茅醇(8.7%),而柠檬香蜂草的主要成分则为β-石竹烯(11.4%)、异戊醇(9.5%)、月桂烯(9.0%)、3-辛酮(8.4%),顶空固相微萃取和气相色谱-质谱(GC-MS)联用技术比动态顶空采样和热脱附/GC/MS联用技术所得到精气成分种类多,且主要成分差异性明显.与精油相比,香叶天竺葵精气与精油的共有成分为香叶醇、香茅醇、α-水芹烯、罗勒烯、芳樟醇、薄荷酮、异薄荷酮、丙酸香茅酯、α-石竹烯;柠檬香蜂草精气和精油的共有成分是甲基庚烯酮、芳樟醇、香茅醇、α-石竹烯.
The chemical composition of phytonciders from the Pelargonium graveolens L and Melissa officinalis L are collected and identified by headspace solid phase micro extraction（HS-SPME）with gas chromatography-mass spectrometry（GC-MS）,and their relative contents are determined by normalization of area.A total of 62 and 43compounds are identified from P graveolens and M officinalis,which account for 99.4% and 99.9% of the total aroma components,respectively.The main constituents of phytoncider are geraniol（17.8%）,guaiazulenum（14.6%）,d-cadinene（12.0%）and citronellol（8.7%）in P graveolens,β-caryophyllene（11.4%）,isoamyl alcohol（9.5%）, myrcene（9.0%）and 3-octanone（8.4%）in M officinalis.The HS-SPME can detect more volatile ingredients than the purge trapthermal desorption（P T-TD）,and have obvious different in the main volatile ingredients.The common constituents of the essential oil and the phytoncider are geraniol,citronellol,α-phellandrene,ocimene,linalool, menthone,isomenthone,propionate ester lemongrass,α-caryophyllene in P graveolens,methyl heptenone,linalool,citronellol,α-caryophyllene in Mofficinalis.
