The genus Dorema (Apiaceae) is represented in the flora of Iran with seven
species of which two, D. ammoniacum D. Don. and D. aucheri Boiss. are
endemic. Ripe fruits of D. ammoniacum collected just in the deciduous time
were subjected to hydrodistillation to yield the essential oil, which was
subsequently analyzed by GC and GC-MS. Twenty-nine compounds were identified
and quantified, representing 95.1 % of the total oil. (Z)-Ocimenone (22.3 %)
and (E)-ocimenone (18.1 %) were the main components of the oil. In vitro
antimicrobial activity of the oil was evaluated against seven Gram-positive
and Gram-negative bacteria (Bacillus subtilis, Enterococcus faecalis,
Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli,
Pseudomonas aeruginosa and Klebsiella pneumoniae) and three fungi (Candida
albicans, Saccharomyces cerevisiae and Aspergillus niger). The results of the
antimicrobial assay of the oil by the disc diffusion method and the MIC
values indicated that the oil exhibited moderate to high antimicrobial
activity, especially against B. subtilis and S. epidermidis with MIC value of
3.75 mg ml-1.
