东北羊角芹籽挥发性成分的GC/MS分析

[目的]对东北羊角芹籽挥发油化学成分进行研究。[方法]采用超临界CO2流体萃取东北羊角芹籽中的挥发油，然后用GC-MS进行成分分析，用峰面积归一化法定量，并与水蒸汽蒸馏法获得的精油成分进行比较。[结果]用从超临界萃取法萃取挥发油中，共鉴定出18种成分，主要成分为芹菜脑（59．5％）、十一烷（18．99％）和柠檬烯（5．23％）。水蒸汽蒸馏法提取芹莱籽，共鉴定出14种成分，主要成分为芹菜脑（21．63％）、十一烷（41．14％）和柠檬烯（13．04％）阻水芹烯（6．82％）。虽然2种方法得到的东北羊角芹籽主要成分的组成不相同，但两者所含芹菜脑都较多，表明东北羊角芹籽挥发油的代表化合物为芹菜脑。[结论]该研究为东北羊角芹籽活性成分的研究提供了理论依据。

GC/MS Analysis of Volatile Components from Aegopodium alpestre Seeds

[Objective] The aim was to study the chemical conponents of volatile oil from Aegopodium alpestre seeds.[Method] The volatile oil from A.alpestre seeds was extracted by the supercritical carbon dioxide fluid extraction,its components were analyzed by GC-MS,it was quantified by the peak area normalization and the essential oil components extracted by the method was compared with that by steam distillation.[Result] 18 components were identified from the volatile oil extracted by the supercritical extraction a...
