(green type) and O. basilicum (purple type)—were carried out.
The oils were obtained by hydrodistillation and were analyzed by GC and GC/MS.
The main components of the oil of the O.basilicum (green type) were methyl chavicol (62.5%), geranial (12.5%) and neral (9.9%) while in the oil of O.basilicum (purple type), trans-a-bergamotene (17.5%), linalool (17.0%) and 1,8-cineole (9.0%) were the prominent components.
The antimicrobial activity of each oil was determined by measurement of the growth inhibitory zone, against three Gram positive, one Gram negative and one fungus using the well diffusion assay.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/55 [article] Composition and antibacterial activity of the essential oil of a green type and a purple type of ocimum basilicum L. from Iran [texte imprimé] / M.

Two essential oils were analyzed by GC-FID and GC/MS.
The major components of O. minutiflorum oil were carvacrol (73.93%) and p-cymene (7.20%).
The essential oil of O. minutiflorum exhibited an extremely strong activity against tested plant pathogenic bacteria such as Agrobacterium spp., Erwinia spp., Rathayibacter spp., Xanthomonas spp., Clavibacter sp. and Curtobacterium sp., but did not show any antimicrobial activity against Pseudomonas spp.
The minimum inhibitory concentration (MIC) values for bacterial strains which were sensitive to the essential oil of O. minutiflorum and S. erytrantha subsp. erytrantha were in the rage of 125–400 µg/mL and 300-500 µg/mL, respectively.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/55 [article] In vitro antimicrobial activities of essential oils from origanum minutiflorum and sideritis erytrantha subsp. erytrantha on phytopathogenic bacteria [texte imprimé] / S.

Seven essential oils of shoots (without inflorescences and seeds) and one oil of inflorescence were obtained by hydrodistillation and analyzed by GC and GC/MS.
Predominant constituents in all oils were ledol (21.0–32.2%) and palustrol (26.2–37.9%).
The oils richest in ledol and palustrol were found in April and October.
To evaluate the amounts of these compounds in the shoots, the percentages were related to the contents of the oils obtained from shoots.
Calculated amounts of ledol and palustrol were largest in shoots during flowering in May.
The inflorescence oil (11.4%) and shoot oil (7.5%) obtained from L. palustre during seed formation in June contained considerable amounts of myrcene.
Cyclocolorenones (2.7–6.5%) were among six main constituents.
Monoterpenoids 2-methyl-5-(3-furyl)-3-penten-2-ol, 5-(3-furyl)-2-methyl-1-penten-3-one (lepalone) and 5-(3-furyl)-2-methyl-1-penten-3-ol (lepalol) were found in all oils.
The largest amounts of furyl compounds were produced by L. palustre in September (9.5%) and October (14.7%).
Sixty-nine identified compounds comprised 95.7–99.3% of the oils.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/55 [article] The variability of the essential oil composition of wild ledum palustre L. shoots during vegetation period [texte imprimé] / R.

The volatile oil sample investigated in this work contained mainly thymol (57.4%), carvacrol (13.5%), g-terpinene (5.6%), and p-cymene (5.2%).
The in vitro antibacterial experiments revealed that on tested bacteria the minimum inhibitory concentration (MIC) ranged 40–80 µL/L and the minimum bactericidal concentration (MBC) 80–150 µL/L.
These findings support the idea that the C. aromaticus essential oil sample tested here could be suitable for use as a natural active ingredient in natural and low-cost drugs against oral microflora.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/55 [article] Antibacterial activities of coleus aromaticus benth (Lamiaceae) essential oil against oral pathogens [texte imprimé] / K.

The experiment was conducted in a greenhouse and the treatments consisted of application of GA3, ethephon and kinetin at 100 mg/L.
Applications were performed at 30, 50 and 70 days after sowing, respectively, and essential oil yield was assessed at 90 days after sowing in two harvesting times: 10 am and 5 pm.
Thus, samples of 100 g shoot (stem plus leaves) and 50 g inflorescences were separated in order to isolate the oil and estimate its volume.
To analyze the oil composition, oil samples were analyzed by GC/MS. Plants treated with ethephon had the highest essential oil yield, which were the lowest in those treated with GA3.
The harvest performed at 10 am had the highest oil yield.
The components identified in the oil were linalool, geraniol, eugenol, a-guaiene, germacrene D, (E,E)-a-farnesene and epi-a-cadinol. Treatment with kinetin increased linalool and eugenol levels, whereas ethephon treatment increased eugenol content.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/55 [article] Yield and composition of the essential oil of basil on plant growth regulators application [texte imprimé] / E.

Eighteen components were identified in the oils from leaves, stems, flowers and roots, comprising 87.1%, 93.1%, 94.9%, and 96.4% of the oils, respectively.
Petiveria alliacea produced an oil dominated by benzenoids and polysulphide compounds, with the principal components being benzyl alcohol (46.6% in the root oil); carvacrol (50.9% in the leaf oil, 48.3% in the stem oil and 29.7% in the flower oil); (Z)-3-hexenyl benzoate (18.6% in the leaf oil, 9.5% in the stem oil and 30.5% in the flower oil) and dibenzyl disulphide (17.6% in the leaf oil, 23.1% in the stem oil, 15.7% in the flower oil and 19.1% in the root oil).
The acaricidal activities of the oils against Tetranychus urticae were also investigated.
The lowest values of LC50 were observed for the flower oil (0.16 µL/L of air) and root (0.12µL/L of air), which did not differ significantly between themselves.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/55 [article] Acaricidal activity and essential oil composition of petiveria alliacea L. from pernambuco (Northeast Brazil) [texte imprimé] / I. de A.

The antimicrobial capability of these oils was determined against ten strains of Gram-negative and Gram-positive bacteria, including some phytopathogenic strains.
The antibacterial activity of the oils was expressed as minimum inhibitory concentrations (MICs).
All oils showed good antibacterial activity against both Gram-negative and Gram-positive bacteria.
The MICs for selected oils ranged 15–250 μg/mL.
The lowest MICs were 15 μg/mL and 20 μg/mL against Xanthomonas citri strains, respectively.
The antioxidant and antiradical scavenging properties of the selected oils were tested by means of 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay.
All examined oils exhibited a free radical scavenging activity, ranging 20–70% of DPPH inhibition.

The species, subspecies, varieties, and hybrids found thus far in Iran amount to 7,576 (almost 6,417 species, 611 subspecies, 465 varieties, and 83 hybrids), 2,100 taxa of which are endemic.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/55

Titre : The efficacy of the essential oils of sri lankan cinnamomum zeylanicum fruit and micromelum minutum leaf against callosobruchus maculatus (F.)

Walp.] in Sri Lanka.
Essential oils isolated from Cinnamomum zeylanicum fruit and Micromelum minutum leaves were tested for potential insecticidal activity against C. maculatus.
The adults of C. maculatus were susceptible to both fumigant and contact toxicity of C. zeylanicum fruit oil and M. minutum leaf oil.
In the fumigant toxicity assay LC50 value (0.801 g/L) of M. minutum leaf oil was lower than that of C. zeylanicum fruit oil.
LC50 values of 0.071 g/L and 0.795 g/L were obtained for the contact toxicity of M. minutum leaf oil and C. zeylanicum fruit oil, respectively.
Oviposition and F1 adult emergence were significantly inhibited by C. zeylanicum fruit oil and M. minutum leaf oil at concentrations higher than 1.25 g/L and 0.25 g/L, respectively in the contact toxicity and 1.00 g/L and 3.00 g/L respectively in the fumigant toxicity.
Repellent activity of M. minutum leaf oil was more potent to C. maculatus than C. zeylanicum fruit oil at doses ranging 10–80 mg.
Analysis of the two oils revealed that bicyclogermacene (16.0%) was the major constituent of M. minutum leaf oil and b-ylangene and linalool (13.9 % and 13.2 %, respectively) were in the C. zeylanicum fruit oil.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/55 [article] The efficacy of the essential oils of sri lankan cinnamomum zeylanicum fruit and micromelum minutum leaf against callosobruchus maculatus (F.)
