The main objective of this study was to analyze and identify the essential oil composition of S. officinalis populations growing in Republic of Macedonia and to evaluate these data according to different standards’ requirements for, commercially most utilized, Dalmatian sage. The essential oil yield, obtained after hydrodestilation from leaves, of three different populations of Salvia officinalis L. from Republic of Macedonia was determined, varying from 1.40 to 3.46%. The GC/FID/MS analysis of the composition of the essential oils revealed 63, 57 and 51 components in Galicica Mtn., Jablanica Mtn. and Karaorman Mtn. sage populations, respectively. The main components of the oil, in all three samples, were the terpene hydrocarbons, encompassing the monoterpenes: camphor (13.15 - 25.91%), α-thujone (19.25 - 26.33%), β-thujone (2.03 - 5.28%), 1,8-cineole (6.51 – 13.60%), α-pinene (0.93 – 1.47%), borneol (1.07 – 4.67%), then sesquiterpenes: trans (E)-caryophyllene (1.72 – 5.33%), α-humulene (2.89 – 7.99%), viridiflorol (4.27 – 7.99%), and the diterpene manool (2.13 - 3.79%). Thus, our results for the essential oil composition of sage complied with the reference values specified in the DAC 86 monograph for Salvia essential oil.

A total of 49 and 41 components, respectively, were identified accounting for 88.1% and 74.4% of the oils of O. basilicum and O. minimum, respectively. The oil of O. basilicum contained, as main components, methyl eugenol (78.02%), α-cubebene (6.17%), nerol (0.83%) and ε-muurolene (0.74%). Major compounds in the volatile oil of O. minimum were geranyl acetate (69.48%), terpinen-4-ol (2.35%) and octan-3-yl-acetate (0.72%). The essential oil of O. basilicum was characterised by its high content of methyl eugenol (78.02%), whereas the most important essential oil constituent of O. minimum was geranyl acetate (69.48%).

A water-distilled essential oil (EO) from the aerial parts of Pimpinella cypria Boiss. (Apiaceae), an endemic species in northern Cyprus, was analyzed by GC-FID and GC-MS. Forty-five compounds were identified in the oil, which comprised 81.7% of the total composition. The compound classes in the oil were oxygenated sesquiterpenes (33.9%), sesquiterpenes (22.0%), monoterpenes (11.4%), oxygenated monoterpenes (2.6%), and phenylpropanoids (7.5%). The main components of the oil were ( Z)-β-farnesene (6.0%), spathulenol (5.9%), ar-curcumene (4.3%), and 1,5-epoxy-salvial(4)14-ene (3.8%). The P. cypria EO deterred yellow fever mosquitoes (Aedes aegypti) from biting at a concentration of 10 μg/cm2 in in vitro bioassays. The oil was tested for repellency in assays using human volunteers. The oil had a minimum effective dosage (MED) for repellency of 47 ± 41 μg/cm2 against Ae. aegypti, which was less efficacious than the positive control N,N-diethyl-3-methylbenzamide (DEET). In larval bioassays, P. cypria EO showed an LC50 value of 28.3 ppm against 1st instar Ae. aegypti larvae. P. cypria EO demonstrated dose dependent repellency against nymphs of the lone star tick, Amblyomma americanum. Between 45.0% and 85.0% repellency was observed at concentrations ranging from 26 to 208 μg/cm2. However, P. cypria EO was less effective compared with DEET in the tick bioassays. Cytotoxicity assays showed that the P. cypria EO did not exhibit significant effects up to the maximum treatment concentration of 50 μg/mL on HEK293, PC3, U87MG, and MCF cells. P. cypria EO also demonstrated moderate antimicrobial activity against Gram-negative and -positive bacteria with MICs ranging from 15.6 to 62.5 μg/mL, except for Candida albicans, which showed the same MIC value of 7.8 μg/mL as the positive control, flucytosine. This is the first report on the chemical composition of P. cypria EO and its insecticidal, toxicant, cytotoxic, and antimicrobial activity.

Wild populations of Croatian clary sage (Salvia sclarea L.) were examined for variability to determine cultivation suitability in Croatia and Israel for breeding purposes. Phenotypic variability (coefficient of variation; %) was recorded for inflorescence weight (39.6%), inflorescence yield (52.8%), and essential oil yield (67.6%) when grown in Croatia. Associations were identified between inflorescence yield and essential oil yield (r = 0.9; P < 0.0001), inflorescence weight and inflorescence yield (r = 0.8; P < 0.0001), and inflorescence weight and inflorescence length (r = 0.6; P = 0.0056), suggesting that populations with elongated inflorescence are indirectly associated with higher essential oil yield. In Israel, the populations reached full bloom between the end of May and early June, corresponding on average to 397.5 days post planting. Linalyl acetate, linalool, α–terpineol, sclareol, and geranyl acetate were the leading essential oil components in both Croatia and Israel. The principal compounds in the oil were linalyl acetate (48.5%) and linalool (17.7%), signifying that the Croatian populations were of the linalool chemotype. A two-way ANOVA indicated an interaction between growing location (Croatia vs. Israel) and population for linalool (P = 0.02), α–terpineol (P = 0.007), and linalyl acetate (P = 0.09); evidence of an environmental effect on essential oil composition. The variation observed suggested that the wild population of clary sage in Croatia had the genetic heterogeneity essential for breeding. Nevertheless, the differences in essential oil composition between Croatia and Israel suggest that breeding efforts should be separately focused for each agriculture production system.

The essential oils from aerial parts of Ferulago pachyloba (Fenzl) Boiss., F. platycarpa Boiss. Bal., F. isaurica Peşmen, and F. longistylis Boiss. (Apiaceae) were obtained by hydrodistillation and analyzed by GC and GC-MS. The highest oil yield (1.50%) was obtained from F. pachyloba followed by F. longistylis (0.16%), F. isaurica (0.08%) and F. platycarpa (0.07%). Fifty-three compounds were identified in the oil of F. pachyloba with ( Z)-β-ocimene (25.7%) and α-pinene (9.8%) as main constituents; sixty-seven in the oil of F. platycarpa with 2,3,6-trimethylbenzaldehyde (29.8%) and cis-chrysanthenyl acetate (24.2%) as main components; seventy-eight in the oil of F. isaurica with nonacosane (25.5%) and hexadecanoic acid (14.8%) as main constituents; and fifty-nine in the oil of F. longistylis with 2,3,6-trimethylbenzaldehyde (32.7%) and bornyl acetate (12.6%) as main components. Quantitative and qualitative differences in the oil compositions of these four species were observed.

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.
