AB  - Two Asteraceae species, <i>Clibadium surinamense</i> L. and <i>Montanoa grandiflora</i> D.C., were analyzed to determine the composition of the essential oil and to search for phototoxic compounds. <br/>
Three parts of the plants were studied, inflorescence, stems and leaves. Intra and interspecific differences were found in the essential oil composition, which was determined by gas chromatography. <br/>
In the chromatographic profiles, run for phototoxic compounds, spots for these products were present in the Clibadium surinamense extracts, but were absent in <i>Montanoa grandiflora</i>. <br/>
From the hexane extract of <i>Clibadium surinamense</i> inflorescence 2 new polyacetylene esters were isolated, ichtyothereol capric ester and its derivate tetrahydroichthyothereol-7’- en-miristic ester.
