摘要
目的:研究地锦草的挥发性成分。方法:采用顶空固相微萃取-气质联用技术对地锦草全草挥发性成分进行分析和鉴定,并用峰面积归一化法计算其相对百分含量。结果:从地锦草中共鉴定出22种成分,相对含量占挥发性成分总峰面积的93.89%,其中主要成分为酮(32.33%)、酸(25.32%)和酯(14.55%)等。结论:研究表明含量较高的挥发性成分为棕榈酸(20.35%)、植醇(16.41%)和2-甲氧基-4-乙烯苯酚(10.98%)。其中二氢猕猴桃内酯和可巴烯可能是地锦草主要的赋香成分。
Objective： To study the volatiles from E. humifusa Method： The volatile compounds from Euphorbia humifusa were extracted by head-space solid-phase micro-extraction （HS-SPME） coupled with gas chromatography-mass spectrometry （GC-MS）. A quantitative analysis in percentage was performed by peak area normalization measurements. Result： Twenty-two compounds were identified, presenting for 93.89% of total volatiles. The volatile constituents were mainly ketones （32.33%）, acids （25.32%） , esters （ 14.55% ） , and other substances. Conclusion： The main compounds were N-hexadecanoic acid （20.35%）, phytol （ 16.41% ）, 2-methoxy-4-vinylphenol （10.98%） and so on. The main fragrance constituents were dihydroactindiolide and copaene.
