摘要:

以吉林省产藿香为研究对象,采用水蒸气蒸馏法提取藿香中挥发油,利用气相色谱-质谱(GC-MS)联用法和自动质谱退卷积定性系统(AMDIS),结合程序升温保留指数(PTRI)对提取的挥发油成分进行分析,采用峰面积归一化法确定各组分的相对含量,结果共分离出168种化学成分,鉴定出其中46种,占挥发性物质总峰面积的91.72%,主要成分有脱氢香薷酮(47.65%)、胡椒酚甲醚(15.01%)、香薷酮(6.16%)、蛇麻烯(5.74%)、n-十六酸(2.47%)、亚麻酸(1.84%)等。

Abstract:

The volatile oil in Agastache rugosa from Jilin province, China was extracted by steam distillation and
analyzed by gas chromatography-mass spectrometry with automated mass spectral deconvolution and identification system
(GC-MS-AMDIS) based on the temperature-programmed retention index (PTRI). The relative concentration of each
component was determined by peak area normalization. A total of 168 compounds were isolated, of which 46 compounds
were chemically identified and accounted for 91.72% of the total peak area. The major components identified were dehydroelsholtzia
ketone (47.65%), methyleugenol (15.01%), elsholtzia ketone (6.16%), humulene (5.74%), n-hexadecanoic acid
(2.47%), and linolenic acid (1.84%).
