Abstract:	The essential oils of six Eupatorium species were obtained by hydrodistillation and analysed by GC-MS. The oil of E. macrophyllum was rich in sabinene (46.7%) and limonene (23.3%). The oil of E. laevigatum was mainly constituted by a mixture of aristolone+laevigatin (23.6%), globulol (16.2%) and germacrene D (8.6%). The principal constituents of the oils of the chemotypes A and B of E. squalidum, E. amygdalinum and E. conyzoides were caryophyllene oxide (17.4-30.1%), globulol (25.1%), germacrene D (10.4-21.6%), spathulenol (14.2%) and β-caryophyllene (7.1-12.3%). The oils of the chemotypes A and B of E. marginatum were dominated by α-zingiberene (57.5%), α-gurjunene (19.5%), germacrene D (14.8%), (E)-8-bisabolene (9.7%) and α-selinene (9.0%). © 2002 Published by Elsevier Science Ltd.
