Objective: To evaluate the essential oil composition and antimicrobial activity of an Algerian\udendemic plant, Daucus aristidis Coss. (Apiaceae) (D. aristidis) (synonym Ammiopsis aristidis\udBatt.) collected in pre-flowering stage in East of Algeria.\udMethods: The aerial parts of D. aristidis Coss were collected. Essential oil (in pre-flowering\udstage) obtained by hydrodistillation was investigated for the first time by gas chromatograph\udand gas chromatograph-mass spectrometer and evaluated for their in vitro antimicrobial activity\udby the disc diffusion method at various dilutions of the oil.\udResults: The main components of D. aristidis oil in pre-flowering stage were α-pinene\ud(20.13%), cedrol (20.11%) and E-asarone (18.53%). D. aristidis oil exhibited an antibacterial\udactivity against almost all the strains tested except for Klebsiella pneumoniae ATCC 700603\udK6 and Enterococcus faecalis ATCC 49452 which exhibited a resistance against the oil with all\uddilutions. Also, the oil of D. aristidis had no activity against all fungi tested.\udConclusions: This is the first report on the volatile constituents and antimicrobial activity of\udD. aristidis in pre-flowering stage. The studied essential oil possesses moderate antibacterial\udactivity against almost all strains tested but no antifungal activity
