Chemical composition, allelopatic and antimicrobial potentials of the essential oil of Zosima absinthifolia (Vent.) Link fruits from Iran.

The chemical composition of essential oil obtained by hydrodistillation from the dried fruits of Zosima absinthifolia was analysed by GC-MS. Twenty-four compounds were characterised in the oil. The major components of the oil were octyl acetate (87.48%), octyl octanoate (5.03%) and 1-octanol (2.37%). The oil showed modest to weak allelopatic effects and high antibacterial effects against Bacillus subtilis, Bacillus pumilus and further modest to strong effects on different bacteria and fungi.
