Linalool (5.8%) was the only monoterpenoid identified in a significant amount.
Results from analysis of the oil of P. amarus revealed that eighty-two identified compounds were responsible for 87.6% of the oil content.
The “stone-breaker” shrub oil was characterized by the dominance of linalool (36.4%) and phytol (13.0%).

The yield of valerian roots was different at the investigated phases and in years of cultivation, while tested genotypes produced similar root yields.
The highest contents of essential oil and valerenic acids were obtained at different phases by the tested genotypes: strain no. 4 in full bloom (1.3% and 0.266%, respectively) and cultivar ‘Polka’ three weeks after seed harvest (1.25%) and during seed harvest (0.218%).
The lowest contents of the investigated substances were detected at the beginning of growth and after the first frost in both genotypes.
The obtained results revealed significant differences in essential oil and valerenic acids content, which depend on genotype, plant age, harvest time and the year of cultivation.
The results suggest that higher amounts of valerenic acids could be obtained in the second year of cultivation over the period from full bloom (0.278%) to fall rosette phase (0.316%).DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/42#top [article] Content of essential oil and valerenic acids in valerian (Valeriana officinalis L.) roots at the selected developmental phases [texte imprimé] / Katarzyna Seidler-Lozykowska, Auteur ; Sebastian Mielcarek, Auteur ; Marek Baraniak, Auteur . - pp. 413-416.

The highest contents of essential oil and valerenic acids were obtained at different phases by the tested genotypes: strain no. 4 in full bloom (1.3% and 0.266%, respectively) and cultivar ‘Polka’ three weeks after seed harvest (1.25%) and during seed harvest (0.218%).
The lowest contents of the investigated substances were detected at the beginning of growth and after the first frost in both genotypes.
The obtained results revealed significant differences in essential oil and valerenic acids content, which depend on genotype, plant age, harvest time and the year of cultivation.
The results suggest that higher amounts of valerenic acids could be obtained in the second year of cultivation over the period from full bloom (0.278%) to fall rosette phase (0.316%).DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/42#top

The oil composition was analyzed by a combination of GC and GC/MS techniques.
Sixty components, representing 83.1% of the total oil, were identified, six of which have not been previously reported in Centaurea oils.
The principal constituents were identified as caryophyllene oxide (27.0%), phytol isomer (16.5%) and 6,10,14-trimethyl 2-pentadecanone (14.9%).
These results show remarkable qualitative and quantitative differences with previously reported studies for Centaurea species.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/42#top [article] Essential oil composition of centaurea pullata L.

Despite the different strategies devised and employed to reversibly overcome the skin barrier, this non-invasive delivery mode is restricted to potent, low molar mass therapeutic agents.
The use of chemical penetration enhancers is the conventional approach to modify the skin structure and lower its resistance for increased drug permeation.
Over the years, extensive screening and testing have identified different classes of chemicals as potential adjuvants.
Among these, terpenes (constituents of plant essential oils) have been widely investigated as skin penetration enhancers for both hydrophilic and hydrophobic drugs.
In particular, monoterpenes were generally more efficacious probably due to their small molecular sizes.
The main mechanisms of action of terpenes on the skin as determined by several analytical techniques were lipid extraction and phase separation.
Terpenes such as limonene and menthol in experimental patch formulations were demonstrated to be safe on the skin and effective in improving drug delivery across the skin.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/42#top [article] A review on terpenes as skin penetration enhancers in transdermal drug delivery [texte imprimé] / Perry Fung Chye Lim, Auteur ; Xiang Yang Liu, Auteur ; Sui Yung Chan, Auteur . - pp. 423- 428.

Titre : Correlation of antimicrobial activities of various essential oils and their main aromatic volatile constituents Type de document : texte imprimé Auteurs : Martina Höferl, Auteur ; Gerhard Buchbauer, Auteur ; Leopold Jirovetz, Auteur Article en page(s) : pp. 459-463 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Antimicrobial activity Carvacrol Carveol m-cresol o-cresol p-cresol p-cymene Eugenol Thymol Essential oils Cinnamomum zeylanicum Origanum vulgare Pimenta dioica Pimenta racemosa Satureja hortensis Syzygium aromaticum Thymus vulgaris Trachyspermum ammi Olfactory description Index. décimale : 646 Résumé : The pure aromatic volatiles p-cymene, carvacrol, eugenol and thymol as well as commercial essential oils of Cinnamomum zeylanicum, Origanum vulgare, Pimenta dioica, Pimenta racemosa, Satureja hortensis, Syzygium aromaticum, Thymus vulgaris and Trachyspermum ammi were investigated concerning antimicrobial activities.
Therefore, these samples and, as reference substances, synthetic antibiotics and the natural antimicrobial components carveol, m-, o- and p-cresol were tested against strains of two Gram-positive and five Gram-negative bacteria and the yeast Candida albicans using agar dilution and agar diffusion methods.
The analysis of the chemical composition of the essential oils by means of GC and GC/MS focusing on aromatic volatiles produced the following results: C. zeylanicum: eugenol (74.9%); O. vulgare: carvacrol (66.1%) and p-cymene (9.2%); P. dioica: eugenol (76.0%); P. racemosa: eugenol (45.6%); S. hortensis: carvacrol (41.5%), p-cymene (10.7%) and thymol (8.7%); S. aromaticum: eugenol (76.8%); T. vulgaris: thymol (43.4%), p-cymene (23.5%) and carvacrol (4.1%); T. ammi: thymol (43.7%) and p-cymene (17.7%).
All investigated aromatic volatiles and essential oils exhibited strong effects against the yeast Candida albicans and medium to strong antimicrobial activity against the Gram-positive bacteria Staphylococcus aureus and Enterococcus faecalis and the Gram-negative bacteria Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, and Salmonella sp., whereas weaker effects were observed against Pseudomonas aeruginosa.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/42#top [article] Correlation of antimicrobial activities of various essential oils and their main aromatic volatile constituents [texte imprimé] / Martina Höferl, Auteur ; Gerhard Buchbauer, Auteur ; Leopold Jirovetz, Auteur . - pp. 459-463.

Fifty-five compounds were identified in the flower oil (96.8% of total oil) and 58 in the leaf oil (89.4% of total oil).
Both oils were characterised by the high amount of monoterpenes (59.1–75.6%), whereas sesquiterpenes were present in smaller quantity (21.2–29.2%).
The main compounds in the flower oil were sabinene (18.5%), limonene (12.0%), β-phellandrene (12.0%) and terpinen-4-ol (10.6%), while in the leaf oil the most dominant were β-pinene (20.0%) and terpinen-4-ol (12.0%).
The antimicrobial activity of the oils was determined using the agar diffusion and broth microdilution method against bacteria Staphylococcus aureus, St. epidermidis, Micrococcus luteus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli and a yeast Candida albicans.
The best inhibitory effect (MIC 0.6 mg/mL) was exhibited by the flower oil against St. epidermidis, K. pneumoniae and C. albicans, the leaf oil against M. luteus, and both oils against E. coli.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/42#top [article] Composition and antimicrobial activity of essential oils from flower and leaf of laserpitium zernyi hayek [texte imprimé] / Silvana Petrovic, Auteur ; Milica Pavlovic, Auteur ; Visnja Popovic, Auteur . - pp. 467- 470.
