Gas chromatography
"A. dracunculus" oil contained predominantly phenylpropanoids such as the carcinogen methyl chavicol (16.2%) and methyl eugenol (35.8%). Gas chromatography/mass spectrometry analysis of the essential oil revealed the presence of "trans"-anethole (21.1%), α-"trans"-ocimene (20.6%), limonene (12.4%), α-pinene (5.1%), "allo"-ocimene (4.8%), methyl eugenol (2.2%), β-pinene (0.8%), α-terpinolene (0.5%), bornyl acetate (0.5%) and bicyclogermacrene (0.5%) as the main components. The organic compound capillin was initially isolated from "Artemisia capillaris" in 1956.
