Abstract- The essential oil composition from the aerial parts of Ormenis africana (Asteraceae), an endemic species from Morocco, has been investigated by GC/MS. A total of 31 compounds were identified, representing 77%. After fractionation by column chromatography, the main compound was isolated and its structure elucidated by NMR spectroscopy. The essential oil was dominated by oxygenated compounds with spathulenol (45.8%) followed by camphor (7.1%), -cadinol (5.9%) and -bisabolol (5.9%) as the main compounds. This oil can be classified as spathulenol-type according to its spathulenol content. In vitro the antibacterial activity of the whole essential oil against three Gram positive (Bacillus cereus, Enterococcus faecalis, Streptococcus C) bacteria and three Gram negative (Proteus vulgaris, Escherichia coli, Pseudomonas aeroginosa) bacteria, showed significant results. Keywords: Asteraceae, Ormenis africana, Essential oil, Spathulenol, Antibacterial activity.

Leaf Essential Oil

The essential oils from fresh aerial parts of Monticalia greenmaniana (Hieron) C. Jeffrey (Asteraceae) collected in March, were analyzed by GC/MS. Oil yields (w/v) of 0.1% (flowers), 0.07%, (stems) and 0.1% (leaves) were obtained by hydrodistillation. Thirteen, sixteen and eighteen components, respectively, were identified by comparison of their mass spectra with those in the Wiley GC-MS Library data base. The major components of the flower and stem oils were 1-nonane (38.8% flowers; 33.5% stems), α-pinene (29.0% flowers; 14.8% stems) and germacrene D (15.6% flowers; 18.6% stems). However, in the leaf oil, germacrene D was observed at 50.7%, followed by β-cedrene at 8.4 %. The leaf essential oil showed a broad spectrum of antibacterial activity against the important human pathogenic Gram-positive and Gram-negative bacteria Staphylococcus aureus (ATCC 25923), Enterococcus faecalis (ATCC 19433), Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853) and Klebsiella pneumoniae (ATCC 25955) with MIC values ranging from 75 to 6000 ppm.

The aerial parts of Satureja spicigera were collected at full flowering stage at Gazvin, Iran. The essential oil was isolated by hydrodistillation and analyzed by a combination of capillary GC and GC-MS. Fourteen compounds were identified, of which carvacrol (53.74%) and thymol (36.03%) were the main constituents, representing 99.12% of the total oil. The in vitro antibacterial activity of the essential oil was determined against six ATCC standard bacterial strains (Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa) using disc diffusion as well as measurement of minimum inhibitory concentrations. The disc diffusion results and MIC values indicated high inhibitory activity against the test bacteria. The most susceptible organisms were the Gram-positive B. subtilis and S. aureus followed by E. faecalis, usually resistant to most common antibiotics. Among the Gram-negative bacteria, E. coli and K. pneumoniae were highly sensitive to the different oil concentrations in the disc diffusion method. Finally, P. aeruginosa, a highly resistant organism to most antibiotics, showed moderate susceptibility to Satureja spicigera essential oil.
