Analysis of volatile components of Artemisia argyi by simultaneous distillation extraction and gas chromatography-mass spectrometry

Volatile compounds of Artemisia argyi were extracted and analyzed by Gas Chromatography-Mass Spectrometry (GC-MS) with the method of simultaneous distillation extraction (SDE) . When taken diethyl ether as extraction solvent, 62 compounds were identified by GC-MS in the DB-WAX column, and 89 compounds in the HP-5 column;when taken methylene chloride as extraction solvent, 35 compounds were identified by GC-MS in the DB-WAX column, and 106 compounds in the HP-5 column. Totally, 159 compounds were verified by SDE-GC-MS with the two extraction solvent in the two columns. The prominent compounds were Eucalyptol, Caryophyllene oxide, Caryophyllene, 3, 3, 6-trimethyl-1, 5-heptadien-4-one, 3, 3, 6-trimethyl-1, 5-heptadien-4-ol, etc.
