Analysis of the Chemical Composition of Volatile Oil from Agastache rugosa by GC-MS-AMDIS Based on Retention Index

doi:10.7506/spkx1002-6630-201324048

Abstract

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%).

Key words: gas chromatography-mass spectrometry (GC-MS), volatile oil, automated mass spectral deconvolution and identification system (AMDIS), temperature-programmed retention index (PTRI)
