VOLATILE CONSTITUENTS AND ANTIMICROBIAL ACTIVITY OF AMMODAUCUS LEUCOTRICUS

Abstract

Ammodaucus belongs to the family Apiaceae (Umbelliferae), subfamily Apioideae,

trib Caucalideae, and comprises one species in Algeria.

In this work the biological importance of members of this genus promoted us to investigate the fruits of Ammodaucus leucotricus Coss. et Dur , previously not investigated. The present work presents the chemical composition and antibacterial activities of the hydro distilled oils. Volatile components of the fruits of Ammodaucus leucotricus Coss. et Dur. have been studied by gas chromatography-mass spectrometry to afford 14 component, the major components were found to be, 1-cyclohexene-1-carboxaldehyde (56.40%), D-Limonene(28.82%), 2- pentanone-4-hydroxy-4-methyl(5.73%). The antimicrobial activities of the volatil oils were evaluated by disc diffusion method and tested against Gram-positive and Gram-negative bacteria. The volatil oil showed a strong antibacterial activity against Staphylococcus aureus, Escherichia coli and Klebsiella pneumonia.
