The chemical composition and antimicrobial activity of the essential oil of the Balkan endemic species Seseli rigidum Waldst. & Kit. (Apiaceae) was investigated. The monoterpene α-pinene was predominant in the volatile oil from aerial parts (57.4%) and fruit (23.3%). In the essential oil of the aerial parts limonene (6.7%), camphene (5.8%) and sabinene (5.5%) were also present in high amounts, and in the fruit oil, β-phellandrene (17.4%) and sabinene (12.9%). On the contrary, the root essential oil was composed almost entirely of the polyacetylene falcarinol (88.8%). The antimicrobial activity of the root essential oil was significant against Staphylococcus aureus, S. epidermidis, Micrococcus luteus and Enterococcus faecalis (MICs 6.25–25.00 μg/mL). Volatile constituents from the root strongly inhibited the growth of methicillin-resistant strains of S. aureus (MICs 6.25–50.00 μg/mL). Anti-staphylococcal activity can be attributed to the main volatile constituent of S. rigidum root, falcarinol.

The present paper describes the chemical composition and antimicrobial activity of the essential oil of the endemic species Satureja horvatii Silic, collected in Montenegro. The essential oil was obtained from the aerial parts of the plant by hydrodistillation and analyzed by GC-MS. From the 34 compounds representing 100 % of the oil, the major compound was the phenolic monoterpene thymol (63.37 %). The oil contained smaller amounts of g-terpinene (7.49 %), carvacrol methyl ether (4.92 %), carvacrol (4.67 %), p-cymene (4.52%), a-terpinene (1.81 %), borneol (1.58 %), a-thujene (1.56 %), b-caryophyllene (1.55 %) and b-myrcene (1.44 %). The antimicrobial activity of the essential oil of S. horvatii was evaluated using the agar diffusion and broth microdilution methods. The essential oil exhibited antimicrobial activity to varying degrees against all the tested strains. The maximum activity of S. horvatii oil was observed against Gram-positive bacteria (Micrococcus luteus, Staphylococcus epidermidis, Staphylococcus aureus and Enterococcus faecalis) and against the yeast (Candida albicans). The oil exhibited moderate activity against the Gram-negative bacteria Escherichia coli and Klebsiella pneumoniae and weak activity against Pseudomonas aeruginosa. This study confirms that the essential oil of S. horvatii possesses antimicrobial activities in vitro against medically important pathogens.

Fruit Oil

Five different essential oil extractions of the aerial parts of Cleome spinosa Jacq. were examined. The oils obtained by hydrodistillation of the whole aerial parts, aerial parts without flowers (fruit, leaves and stem), flowers, fruits and leaves have been examined by GC-FID and GC-MS. The chemical profiles of the oils reveal the dominance of oxygenated sesqui- and diterpenes, with the exception of the fruit oil, which contained a high content of fatty acids. The most abundant compounds from the whole aerial parts were ( Z)-phytol (31.3%), integerrimine (5.5%) and incensole (4.0%). The major compounds from the aerial portion without flowers were caryophyllene oxide (10.5%), (-)-spathulenol (7.5%) and Z-phytol (6.9%). In the flower oil, the main components were 7-α-hydroxy manool (23.8%), incensole (9.2%) and sclareol (8.7%). The chief constituents in the fruit oil were tetradecanoic acid (40.6%), ( Z)-phytol (6.58%) and sclareol (4.5%). In the leaf oil, ( Z)-phytol (19.5%), 7-α-hydroxy manool (6.8%) and caryophyllene oxide (4.36%) were the predominant compounds. Antimicrobial activity of the oil obtained from the whole aerial part was evaluated against nine microbial strains using a filter paper disc-diffusion method. The volatile oil showed moderate action against seven of the eight bacteria strains used, with significant inhibitory activity against Streptococcus pyogenes Group A when compared with the standard antibiotics, ampicillin and gentamicin. The fungus, Candida albicans was less sensitive to the essential oil. The oils showed moderate insecticidal activity against Cylas formicarius elegantalus, but possessed no antioxidant activity as indicated by the DPPH method. This represents the first report on the chemical composition of the essential oils from C. spinosa found in Jamaica and the in vitro antioxidant, insecticidal and antimicrobial potential of the oil from the aerial parts.

The chemical composition of the essential oils obtained by hydrodistillation from the aerial parts of Thymus serpyllum and Thymus serpyllum‘Aureus’ has been investigated by gas chromatography-mass spectrometry (GC-MS). Forty-seven compounds (99.67% of the total oil) wereidentified in the essential oil of T. serpyllum. The main components found in the oil were carvacrol (37.49%), -terpinene (10.79%), -caryophyllene (6.51%), p-cymene (6.06%), (E)--ocimene (4.63%) and -bisabolene (4.51%). Similarly, carvacrol (44.93%), -terpinene(10.08%), p-cymene (7.39%) and -caryophyllene (6.77%) dominated in the oil of T. serpyllum ‘Aureus’. A total of forty three compounds wereidentified in this oil, representing 99.49% of the total oil content. On the basis of the obtained data it was proved that the content of 1-octen-3-ol,eucalyptol, (Z)--ocimene, (E)--ocimene, -terpinene, carvacrol methyl ether, germacrene D and -bisabolene was significantly higher for T.serpyllum while T. serpyllum ‘Aureus’ was characterized by a significantly higher content of 3-octanone, 3-octanol, p-cymene, borneol andcarvacrol. The isolated essential oils were evaluated for their antimicrobial activity against nine reference strains (Escherichia coli, Staphylococcusaureus, Staphylococcus epidermidis, Streptococcus agalactiae, Enterococcus faecalis, Bacillus cereus, Micrococcus luteus, Proteus vulgaris and Candidaalbicans) by the microdilution technique. Based on this test, the minimum inhibitory concentrations (MIC) of essential oil were calculated. Thevolatile oil obtained from T. serpyllum showed the highest antimicrobial activity relative to the strain of E. coli (MIC=0.025 μL/mL) and to theyeast C. albicans (MIC=0.05 μL/mL). Similarly, a significant antimicrobial activity exhibited T. serpyllum ‘Aureus’ essential oil, although the MICvalues obtained in that case for E. coli and C. albicans strains were twice as high and were respectively 0.05 μL/mL and 0.1 μL/mL.

The essential oils of Blainvellea rhomboidea (Asteraceae) were obtained by hydrodistillation and analyzed by GC/MS and GC/FID. Initially, the essential oil from the aerial parts was investigated. From the 18 identified components, 5-indanol (14.5%) followed by p-cymen-8-ol (10.1%), β-caryophyllene (9.6%), caryophyllene oxide (9.6%), limonene (8.6%), terpinolene (7.8%), and spathulenol (7.7%) were the major constituents. The oil was tested against seven bacterial strains and the results showed significant antimicrobial activity. As a consequence, the essential oils from leaves and from flowers were analyzed separately. The major constituents of the leaf oil were terpinolene (21.2%), β-caryophyllene (19.2%), spathulenol (9.1%), caryophyllene oxide (7.4%), and bicyclogermacrene (7.1%), while the oil of the flowers contained terpinolene (28.1%), 5-indanol (16.3%), p-cymen-8-ol (15.3%) and limonene (14.7%) as prevalent compounds. The oils were tested against the same bacterial strains and the flower oil was the more active. These results indicated that the components of the essential oil from flowers seem to be responsible for the activity.
