Abstract

The essential oil from flowers, leaves, stems and roots of Erigeron annuus (L.) Pers. was analyzed by GC, GC-MS and 1H-NMR spectroscopy. More than 60 compounds were identified. Germacrene D (47.2%) and (Z)-lachnophyllum ester (10.2%) were the main constituents of the flower oil. The leaf oil and stem oil contained mainly germacrene D (55.6% and 44.5% respectively) and β-caryophyllene (9.4% and 13.4%), whereas in the root oil dominated matricaria ester (59.9%) and (Z)-lachnophyllum ester (34.9%).
