The composition of the essential oil (EO) obtained from dry leaves of Chiliadenus bocconei Brullo (Asteraceae subfam. Inulae), a Maltese endemic aromatic plant, collected in two different seasons, was evaluated in this work. The main EO components identified in the summer foliage were camphor (25.6%), borneol (27.1%) and τ-cadinol (13.9%). In the winter foliage τ-cadinol was the most represented compound (59.5%), followed by camphor (13.1). A comparison is also made between the EO composition of the two samples of C. bocconei and the EO obtained from different aerial parts of C. lopadusanus, an endemic plant of Lampedusa Island, another Mediterranean Island.
