摘要

目的: 研究超临界CO2萃取法(SFE)提取藿香蓟精油的化学成分及含量。方法: 采用超临界CO2萃取法(SFE)提取藿香蓟精油

用气相色谱-质谱联用技术(GC-MS)分析其成分

并用峰面积归一法计算各组分相对百分含量。结果: 鉴定了60个成分

占总组分的95.96％

主要成分有对甲氧基肉桂酸乙酯(12.78%)、桉叶油素(11.59%)、 α -蒎烯(8.52%)、樟脑(5.03%)、3-(1-甲醛基-3

4-亚甲二氧基)苯甲酸甲酯)(4.24%)

马鞭烯酮(3.52%)

β-石竹烯(3.33%)

龙脑(3.14％)等

与水蒸气蒸馏法(SD)提取的挥发油成分有非常明显的差别。结论: 该研究可为藿香蓟的综合开发利用提供科学依据。

Abstract

Objective: To analyze the main chemical components of essential oil from Aqeratum conyzoides by supercritical CO2 fluid extraction(SFE). Method: The essential Oil from A. conyzoides was extracted by SFE

and the chemical components was analyzed by gas chromatography and mass spectrometry(GC-MS)

then the relative content of each component was determined by area normalization. Result: Sixty components

95.96％ of the total oils had been identified

and the main components were 3-(4-methoxyphenyl)-2-propenoic acid ethyl ester(12.78%)

eucalyptol(11.59%)

1R-α-pinene(8.52%)

(+)-2-bornanone(5.03%)

3-(1-formyl-3

4-methylenedioxy)methyl benzoate(4.24%)

L-verbenone (3.52%)

caryophyllene(3.33%)

L-borneol(3.14％).The main components were extremely different from the essential oil extracted by team distillation(SD). Conclusion: The present experiments provided a scientific basis for the integrated utilization of A. conyzoides.
