中文摘要: 利用顶空-固相微萃取技术(HS-SPME)吸附泰国芫荽与云南芫荽不同器官中挥发性成分的组成。经气相色谱 质谱联用仪(GC-MS)分析测定, 并用峰面积进行归一化定量,泰国芫荽与云南芫荽分别鉴定出 40 种和 31 种化学成 分,其中泰国芫荽从根、茎和叶分别鉴定出 21、33 种和 35 种,分别占总峰面积的 92.18 %、91.35 %和 93.15 %,而云南芫 荽分别从根、茎和叶鉴定出 16、17 种和 30 种,分别占总峰面积的 94.10 %、92.66 %和 98.66 %。不同器官主要挥发性成分 具有相似性,即醛类和醇类,其中,2-十二烯醛为二者共同特征挥发性成分。泰国芫荽根中主要成分为 2-十二烯醛和 1-乙烯基-环十二醇,茎和叶中主要成分为 2-十二烯醛;云南芫荽根中主要成分为 2-十二烯醛,茎和叶中主要成分为 2-十二烯醛和和 1-乙烯基-环十二醇。

Abstract:The volatile compounds in different plant organs of Eryngium foetidum L. and Yunnan Coriandrum sativum L. were extracted by using head-space solid phase microextraction (HS-SPME), and analyzed by gas chormatograph-mass spectrophotoerter (GC-MS). A quantitative analysis in percent was performed by peak area normalization measurements. 21, 33 and 35 volatile were identified in root, stalk and leaf, which the contents of were 94.10 % ,92.66 % and 98.66 % of total area peak, respectively. The volatile compounds in different organs have similarities, which are aldehydes and alcohols. 2 -dodecenal was the specific volatile compounds in both Eryngium foetidum L. and Yunnan Coriandrum sativum L. 2 -dodecenal and1 -ethenyl -cyclododecanol are the main volatiles in root of Eryngium foetidum L., while 2-dodecenal in both stalk and leaf. In Yunnan Coriandrum sativum L., 2 -dodecenal is the main volatile in root and stalk, and 1 -ethenyl -cyclododecanol in leaf.
