Components of essential oils of Kakushitsu (Daucus carota L. and Carpesium abrotanoides L.).

Abstract

The essential oils of two commercial herb samples Kakushitsu Korafukushi (Daucus carota L.) and Tenmyoseishi (Carpesium abrotanoides L.) were investigated. These essential oils were obtained by steam distillation, and analyzed by GC, GC-MS, IR and 1H-NMR. Korafukushi oil had a sweet anis like odor, and the main components identified were: β-bisabolene, cis- and trans- asarone, asarone aldehyde, and phenolic compounds, such as eugenol, 2-hydroxy-4-methoxyaceto-phenone and vanillin. Tenmyoseishi oil had a fatty acid odor, and the main components identified were: β-bisabolene, C2_??_C16, C18 fatty acid. Characteristic components: lactones, such as γ-nonalactone, dihydroactinidiolide, butyl phthalide, C3_??_C14 aliphatic alcohols and aldehydes.
