“…40 With this study we contribute to the knowledge of the chemical composition of Spanish flora and to extend the classification proposed by Dr Baser. 19,20 We have found qualitative and quantitative differences between our results and those previously published on this species. 21 Only 29 compounds are common to both studies and 44/73 compounds identified have not been previously reported in this species (Table 3).…”

“…Nevertheless, one species of this genus, S. perfoliata, has been described to present diterpenes as major constituents. 19 The oil yield of the species belonging to this genus is highly variable, from 0.02% in S. curvidens 19 to 0.83% in S. congesta, 15 although it could be caused by the variability of this genus, which includes different sections and subsections with annual and perennial species. 37,38 Although the yield seems to change according to the plant biotype, previous studies have also confirmed that the intercrossing species also affect it, as in the case of S. tragoriganum (Table 1 12,13 ).…”

The essential oil from the aerial parts of Sideritis hirsuta L. gathered in Guadalajara Province, Spain, has been extracted by steam distillation and analysed by gas chromatography (GC) and gas chromatography coupled to mass spectrometry (GC-MS). A total of 73 compounds have been identified, monoterpene compounds being the most important. The principal constituents have been identified as β β β β β -phellandrene (23.8%), α α α α α -phellandrene (9.2%), α α α α α -pinene (8.2%) and (Z)-β β β β β -guaiene (8.1%). Although the chemical composition of the essential oil of this species from other provinces is similar, 44 of the 73 identified compounds have not been previously reported in this species. It is the first time that the sesquiterpene (Z )-β β β β β -guaiene (8.1%) has been detected and mentioned as a major constituent in this species, therefore it could be considered to describe a new chemotype for Sideritis hirsuta L.

Oils obtained by hydrodistillation were analyzed by using gas chromatography (GC) and GC/mass spectrometry. 1, and a-terpinyl acetate (13.94% and 14.72%) were the main components from the essential oil of the stem and leaves of laurel, respectively. 1, and (E)-b-ocimene (24.88%) were the major compounds present in the essential oil of fruit. The main constituents of Salvia fruticosa oil were a-pinene (31.50%) and isoborneol (27.17%). b-pinene (20.53%), a-pinene (14.88%), cubebol (15.17%) and d-cadinene (12.99%) were detected as the major constituents of mountain tea (sample A). The principal components detected in the oil of sample B were b-pinene (20.29%), a-pinene (14.82%) and 14-hydroxy-9-epi-caryophyllene (13.99%). The major compounds of ajowan oil had p-cymene (33.06%), g-terpinene (28.66%), thymol (24.11%) and b-pinene (6.74%). The essential oil of Carum copticum was characterized by its high content of p-cymene (33.06%). PRACTICAL APPLICATIONLaurel leaves are commonly used as a spicy, aromatic flavoring for soups, fish, meats, stews, puddings, vinegars and beverages, and form an essential ingredient of the herb mix. The essential oil is used by the cosmetic industry

The antibacterial potential of essential oil from Serbian Sideritis montana L. (Lamiaceae) on different bacteria was investigated. The essential oil was obtained from air dried aerial parts of the plant with 0.03% (w/w) yield by hydrodistillation for 4 h using a Clevenger-type apparatus. The essential oil analyses were performed simultaneously by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) systems. Dominant compounds class is sesquiterpene hydrocarbons. The main constituents of oil were germacrene D (37,9%) and trans-geraniol (26,1%). The antibacterial activity of the essential oil was tested towards 4 different bacteria, laboratory control strain obtained from the American Type Culture Collection (ATCC). Gram negative bacteria were represented by Escherichia coli ATCC 13706, Pseudomonas aeruginosa ATCC 27853, Salmonella enteritidis ATCC 13076 while researched Gram positive strain was Staphylococcus aureus ATCC 29213. Broth microdilution method was used to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Essential oil has been found to have antibacterial activity against all tested bacteria, with a MIC values ranging from 0.03 to 0.06 μl/ml and MBC values from 0.06 to 0.12 μl/ml. Reference antibiotic tetracycline was active in concentrations between 0.025 to 0.1 μg/ml. Essential oil from Serbian S. montana has high antibacterial potential which should be studied further
