title: Volatile constituents of the aerial parts of white salsify (Tragopogon porrifolius L., Asteraceae).
abstract: Tragopogon porrifolius L. grows as a vegetable in southern Italy and all parts of it are edible. In the present study the volatile components of the aerial part are described. Gas chromatography and gas chromatography-mass spectrometry analysis showed the presence of 38 components in all. On the whole, the volatile fraction was constituted mainly by carbonylic compounds (24.6%), phenols (21.5%) and fatty acids and esters (19.7%). The most abundant compounds were 4-vinyl guaiacol (19.0%), hexadecanoic acid (17.9%), hexahydrofarnesylacetone (15.8%) and hentriacontane (10.7%).
