采用顶空固相微萃取-气相色谱质谱联用(HS-SPME-GC-MS)技术分析比较鲜艾叶与干艾叶的挥发性成分。考察了不同萃取头和萃取温度对艾叶挥发性成分的萃取效果,以选用65μm PDMS/DVB SPME萃取头和60℃水浴加热时萃取效果最好;采用峰面积归一化法测定各成分的质量分数,共鉴定出58种挥发性成分,主要为烯烃类、芳香类和醇类物质,占总峰面积90%以上。鲜艾叶与干艾叶均含有莰烯、1-辛烯-3-醇、α-水芹烯、邻聚伞花素、桉油精、石竹烯等,此外又各自具有特有成分,表明艾叶在干制后其挥发性成分发生变化。
採用頂空固相微萃取-氣相色譜質譜聯用(HS-SPME-GC-MS)技術分析比較鮮艾葉與榦艾葉的揮髮性成分。攷察瞭不同萃取頭和萃取溫度對艾葉揮髮性成分的萃取效果,以選用65μm PDMS/DVB SPME萃取頭和60℃水浴加熱時萃取效果最好;採用峰麵積歸一化法測定各成分的質量分數,共鑒定齣58種揮髮性成分,主要為烯烴類、芳香類和醇類物質,佔總峰麵積90%以上。鮮艾葉與榦艾葉均含有莰烯、1-辛烯-3-醇、α-水芹烯、鄰聚傘花素、桉油精、石竹烯等,此外又各自具有特有成分,錶明艾葉在榦製後其揮髮性成分髮生變化。

We analyzed volatile components in fresh and dried leaves of Artemisia argyi Levl.et Vant.with headspace solid phase microextraction(SPME) and GC-MS.We also investigated the impacts of different SPME fibers and extraction temperature on the extracts.Results demonstrate that 65 μm PDMS/DVB fibre and temperature of 60 ℃ exhibit good extraction effect.We employed peak area normalization method to determine the volatile components.Fifty-eight compounds are identified in the fresh and dried leaves of Artemisia argyi,which include alkanes,alkenes and alcohols,and whose area exceeds 90% of the total peak area.Results also show that fresh and dried leaves of Artemisia argyi not only contain identical volatile compounds such as Camphene,1-Octen-3-ol,alpha-Phellandrene,Benzene,1-methyl-2-(1-methylethyl)-Eucalyptol and Caryophyllene,but also contain their own unique volatile compounds.This shows that their volatile components change after dryness.
