Abstract
Ammodaucus belongs to the family Apiaceae (Umbelliferae), subfamily Apioideae, trib
Caucalideae, and comprises one species in Algeria (Quezel and Santa, 1962).
The biological importance of members of this genus promoted us to reinvestigate the volatile constituents
of the fruits of Ammodaucus leucotricus Coss. et Dur., and to carry out a biological study
as far as the antibacterial activity is concerned. The present work deals with the chemical composition
and antibacterial activities of the hydrodistilled oils. After extraction, the oil was analyzed by
gas chromatography–mass spectrometry to afford 14 components. The major components were
found to be, 1-cyclohexene-1-carboxaldehyde (56.40%), D-limonene (28.82%), and 2-pentanone-
4-hydroxy-4-methyl (5.73%). Moreover, the antimicrobial activities of the volatile oils were evaluated
by disk diffusion method against Gram-positive and Gram-negative bacteria. The results
showed a strong antibacterial activity against Staphylococcus aureus, Escherichia coli and Klebsiella
pneumonia.
