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.
The aerial parts of Artemisia Sagebrush were collected in August 2010 from Damavand ( Tehran Province of Iran ). It is air dried in a shadow place. A headspace solid-phase micro-extraction (HS-SPME) method followed by gas chromatography-mass spectrometry (GC/MS) was used for the analysis of volatile compounds in the leaves of Artemisia Sagebrush. The dried plant was powdered and the aroma compounds of a 0.05g were isolated by HS-SPME fiber in 15 min. The chemical compounds of plant were investigated by gas chromatography mass spectrometry (GC/MS). The oven temperature of GC was programmed between 60-250°C using DB-5 column. A total of 51 constituents, representing more than 96% of the volatiles were identified. The main compounds, were isobornyl acetate (19.56%) , eucalyptol (14.81%), (+) trans-chrysanthenyl acetate (12.76%), αcubene (9.70%), borneol (9.06%), caryophyllene (7.03%), camphor (6.83%), γ-elemene (2.16%), umbellul one (1.73%) and copaene (1.37%). This herbal medicine traditionally uses as antiinfectious, anti-bacterial, gastric tonic, digestive and stomachic in Iran. Consequently, this fast and simple method can be used for the analysis of the volatile compounds emitted from Artemisia Sagebrush.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
