Résumé
Fresh and dry Peganum harmala from Morocco were investigated for volatile components. Thirty-one volatile constituents were identified from aerial organs (leaves and stems) and roots. The dry parts were qualitatively richer in volatiles than the fresh ones. The leaves contained more volatile molecules than stems and roots. The main constituents were propylic acid and 2,3-dihydiobenzofurane identified in both fresh and dry materials, 3-octanone present in the aerial parts, and isovanillin detected only in dry P. harmala organs.
