Volatiles composition of aerial parts from medicinal Anacyclus clavatus (Asteraceae) was determined by gas chromatography-flame ionization detector (GC/FID) and gas chromatography-mass spectrometry (GC/MS) analysis. Altogether, 46 compounds were identified representing 81.2% of the total volatiles. The main components were Trans-Chrysanthenyl acetate (12.3%), Cis-Thujone (9.8%), Chrysanthenone (8.2%) and Trans-Thujone (7.3%). The volatile oil was screened for antibacterial and anti-Candida activities using dilution and disc diffusion methods. Thus, the studied fraction showed moderate activities against four Candida species and was most effective against Gram-negativePseudomonas aeruginosa.
Key words: Anacyclus clavatus (Desf.), aerial parts, steam distillation, gas chromatography-mass spectrometry (GC/MS), antimicrobial effects.
