The composition of the essential oil from the ¯owers of Laurus nobilis L. shows dierences with the essential oil of the leaves with a high content of b-caryophyllene (10.0%), viridi¯orene (12.2%), germacradienol (10.1%), b-elemene (9.7%) and (E)-ocimene (8.0%). Dierences between the ¯ower oil and the oils of stem wood and stem bark were also investigated.
