摘要

目的 :分析比较青翘挥发油的化学成分。方法: 采用水蒸气蒸馏法(SD)及CO2超临界萃取法(SFE)提取青翘挥发油

并用气相色谱-质谱联用法分析鉴定其化学成分。结果: SD法提取的挥发油分离出87个色谱峰

共鉴定58个化合物

占挥发油总量的96.99%

SFE提取的挥发油法分离出100个色谱峰

鉴定39个化合物

占挥发油总量的60.50%。结论: SD法提取的挥发油主要化学成分是β-蒎烯

α-蒎烯

(-)-4-松油醇

对伞花烃;SFE法提取的挥发油主要化学成分是努特卡酮

β-蒎烯

对甲氧基桂皮酸乙酯。2种提取方法的化学成分及其含量有较大差异。

Abstract

Objective: To analyze the chemical constituents of the essential oils from Forsythis suspense by different extraction method. Method: The essential oils were extracted by steam distillation (SD) and by supercritical carbon dioxide extraction (SFE) accordingly

and then the constituents were separated and identified by GC-MS. Result: Eighty-seven compounds were isolated and 58 compounds were identified by SD that composed about 96.99% of the total essential oils;And 100 compounds were isolated and 39 compounds were identified by SFE that composed about 60.50% of the total essential oils. Conclusion: The principal chemical constituents of the essential oils by SD are β-pinene

α-pinene (-)-4-terpineol

p-cymene.And the principal chemical constituents of the essential oils by SFE are nootkatone

β-pinene

transethyl-p-methoxycinnamate.There are differences in the chemical constituents and contents by the two extraction methods.
