Hydro-distilled volatile oils from the flowers and leaves of Eupatorium cannabinum L.
which gathered in Touchal on Mountain Alborz (Tehran province) in Iran were investigated
mainly by a combination of GC and GC/MS . Thirty-nine components were identified in the
oils. The main constituents of the essential oils in flowers and leaves were gennacrene D
(27.3%, 37.1%), gemacrene B (12.4%, 11 .7%) and p-caryophyllene (8.6%, 10.1%). Although
the main components of all the oils are similar, their percentages are different.
