Abstract

The hydrodistillated essential oils from leaves and fruits of Ecballium elaterium were analysed by GC-MS. Octyl octanoate (30.0%), 3-(6,6- dimethyl-5-oxohept-2-enyl)-cyclohexanone (20.4%) and hexahydro farnesyl acetone (19.1%) were the main components among 21 constituents characterised in the leaf oil. Twenty-one compounds were also identified in the oil of the fruits, with E-anethol (31.6%) and 3-(6,6-dimethyl-5-oxohept-2-enyl)-cyclohexanone (8.8%) as the main constituents. Furthermore, allelopatic activity of the oils was evaluated using lettuce assay method. The leaf oil exhibited strong allelopathy effects against lettuce.
