“…we have revealed the presence of α-pinene, sabinene, myrcene, α-terpinene and γ-terpinene, α-terpinolene 4-methyl-1-(1-methylethyl)-3-cyclohexen-1-ol and α-cedrol as main constituents. This finding is somehow in contrast with previous reports revealing the presence (in large amounts) of limonene, β-pinene (Emami et al 2011) and α-thujone and β-thujone (Adams 1990). These compounds were not detected in our samples.…”

Essential oils of indigenous in Greece six Juniperus taxa

The chemical composition of 14 essential oils (EOs), obtained from various parts (leaves, fruits, wood) of the six indigenous in Greece Juniperus family taxa, was determined by GC and GC/MS analysis. The insecticidal properties of these EOs were evaluated against Culex pipiens L. larvae of 3rd and early 4th instars, in order to delineate the relationship between the phytochemical content of the EOs and their larvicidal activities. The analytical data indicated that the EOs mainly consisted of monoterpenes, mostly cyclic and only occasionally aliphatic, and to a lesser percent, of diterpenes. The larvicidal bioassays against C. pipiens larvae revealed that the most active EO was derived from the wood of Juniperus drupacea and contains mainly non-oxygenated monoterpenes and a significant amount of diterpenes, displaying the highest chemodiversity. Its initial LC(50) value was 26.47 mg L(-1). On the contrary, the EO isolated from J. phoenicea berries, which consisted of monoterpenes (non-oxygenated, cyclic), was the less active displaying an LC(50) value of 96.69 mg L(-1). In respect to the contained phytochemicals, myrcene was assayed as the most toxic, displaying an LC(50) value of 33.83 mg L(-1), while the four isomers of pinene abundant in all EOs were less active exhibiting LC(50) values ranging from 70.40 to 94.88 mg L(-1). Results herein reveal that the EOs isolated from the studied Juniperus family taxa represent an inexpensive source of natural mosquito control mixtures.

“…This is in accord with similar reports for juniper species from other regions (Elmastaş et al, 2006;Moein et al, 2010;Emami et al, 2011;Höferl et al, 2014;Cioanca et al, 2015;Elmhdwi et al, 2015). However, antioxidant activity as reported in this study did not correlate with the total content of phenolics and flavonoids, except for extracts obtained from cuttings of small seedlings, which shared the highest antioxidant activity with that of C2-type callus and in vitro shoots.…”

Juniperus phoenicea is an ornamental shrub that is also used to flavor food and to supply medicines and timber. Its micropropagation is of industrial concern and can occur by axillary shoot multiplication. Microcuttings of J. phoenicia were established in vitro on Murashige and Skoog (MS) and Rugini Olive (OM) media in glass tubes (25 mm x 150 mm). Factors studied were explant length (0.5 or 1.5 cm) and orientation (horizontal or vertical), media strength (OM, ½OM, MS, ½MS) and the following growth regulators: the anti-auxin 2,3,5-triiodobenzoic acid (TIBA), the cytokinins 6-benzyladenine (BA) and thidiazuron (TDZ), and the growth retardant daminozide (DM). Microcuttings placed vertically on the surface of OM, ½OM and ½MS media without hormones exhibited axillary bud differentiation, but they were swollen and turned brown one month later when placed horizontally on the medium surface. The number of shoots, averaged across OM, ½OM and ½MS media, was significantly higher from longer (1.5 cm) than shorter (0.5 cm) microcuttings (4.11 versus 1.57 shoots microcutting -1 ) after 60 days of culture. TIBA or DM at 0.1 mg l -1 included in OM medium enhanced leaf differentiation, callus induction and formation of adventitious shoots over three months from 0.5 cm long microcuttings taken from in vitro shoots. The formation of adventitious shoots was sporadic and occurred at a rate of 1 shoot microcutting -1 in the presence of 0.1 mg l -1 DM. OM supplemented with 0.1 mg l -1 TIBA resulted in significantly the highest leaf differentiation (55 leaves microcutting -1 ), with a rooting rate of 40%. Contents of phenols, flavonoids and antioxidants were compared for cuttings from young seedlings, callus, in vitro shoots, and seeds. Antioxidant activity was significantly the highest for shoots grown on hormone-free OM medium and callus maintained on OM medium containing 0.1 mg l -1 2,4-D (94.7 and 94.3% inhibition of DPPH free radicals, respectively). Thus, different routes for in vitro regeneration of J. phoenicea can be of potential use for many biotechnological, pharmaceutical and food industry applications.

“…Thyme and its oil have also a long reputation in the Iranian folk [6][7][8] . Essential oils are regarded as important herbal products with biological and pharmacological activities [13][14][15][16][17][18][19][20] . Composition of an essential oil is influenced by a variety of factors related to geographical, climatic, cultivation and seasonal variations.…”

Thyme (Thymus vulgaris L.), family Labiateae, is fairly grown wildly throughout Iran. The essential oil of the aerial parts of T. vulgaris, cultivated in the Khorasan province, North East of Iran, was prepared. The chemical composition of the oil was identified using GC-MS. Twenty-one compounds were identified. The major components of the oil were carvacrol (57.3 %), linalool (11.8 %) and thymol (10.67 %). The amounts of the two main components, carvacrol and thymol, were compared with the results reported from other countries.
