Titre : Essential oil quality and yield with respect to harvest index in tagetes minuta cultivated in sub tropical plains of north India Type de document : texte imprimé Auteurs : Aparbal Singh, Auteur ; S. PS Khanuja, Auteur ; S. J. K. Arya, Auteur Année de publication : 2006 Article en page(s) : pp. 362-365 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Tagetes minuta Asteraceae Stage of harvest Oil yield Essential oil composition Limonene (Z)-β-ocimene Dihydrotagetenone (Z)-tagetone Tagetenone Résumé : Planned studies were carried out to determine the most appropriate stage of economic harvest in Tagetes minuta by examining dry matter partitioning, essential oil yield and quality of oil at different growth stages grown in Lucknow conditions at the Central Institute of Medicinal and Aromatic Plants, Lucknow, India, during winter season 2002–2003. The maximum essential oil yield (1.01 g/plant and 56.1 kg/ha) was obtained upon harvesting at post fowering stage (seed setting stage). Advantage in essential oil yield at this stage was 130%, 34.5% and 36.5% yield enhancement over pre-flowering, 50% and 100% flowering stages, respectively. Flowers and leaves contained the maximum essential oil 2.14% and 1.89% (dry weight basis), respectively. Relative contribution of leaf, flower and stem to essential oil production was 40.7%, 37.8% and 21.5%, respectively. In the oil quality analysis, dihydrotagetone (77.1%) was the predominant component in oil from the leaves while (Z)-β-ocimene, limonene and (Z)-tagetone were the major constituents in the flower oil. The study suggests that T. minuta should be harvested at the post-flowering stage for realizing maximum essential oil yield and its desirable major chemical constituents. The study also differentiated the quality of leaf and fower oil for chemical constituents.

(Apiaceae) were determined during the pre-flowering, full flowering, late flowering, and fruiting vegetative periods. A fruit sample was also studied for comparative purposes. Leaves (0.8–1.8% yield) and stems (0.3–0.7%) reached their maximum oil content during the late flowering period, whereas umbel rays (2.2–3.7%) reached it in full flowering. Oil samples were analyzed by capillary GC and GC/MS: components which were found in amounts greater than 2% were selected to carry out a seasonal study. In the leaf oils, sabinene (12.0–33.9%) and limonene (7.8–23.4%) were the main components, the sabinene level being minimum in full flowering and maximum in fruiting. In stem oils, sabinene (4.7–21.6%) and 2,3,4-trimethylbenzaldehyde (9.3–13.6%) were the main components, the sabinene level being minimum in pre-flowering and maximum in full flowering. In umbel ray oils, sabinene (20.7–43.1%) was the first component in all the phenological periods, followed by α-pinene (7.3–28.2%). Both monoterpenes increased their levels in late flowering and reached minimum amounts in fruiting.

The original material for the research was sage leaves (Salvia offcinalis L.) cv. ‘Bona’, which came from a two-year plantation. A three-year research study proved that the percentage amount of oil in the raw material of sage was related to the harvest time of the crop. It was higher in leaves coming from the second term of crop (middle of September) and ranged from 1.6% to 1.8%. The percentage amount of oil in sage leaves collected in May (frst crop) was lower and fluctuated between 0.8% and 1.4%. Qualitative and quantitative analyses of distilled oils were made using GC and GC/MS. The analyses demonstrated the presence of 31 components in the oil. We found that the oil components varied quantitatively, depending on the harvest time. The main components occurring in sage oil were α-thujone (18.4–27.9%), β-thujone (8.0–15.0%), 1,8-cineole (4.0–14.4%) and camphor (11.7–27.0%).

No meaningful differences were observed comparing the composition of nine geographical origins. Hierarchical clustering and principal component analysis (PCA) of the compositional data of the oil samples confirm the relative homogeneity of V. zizanioides by the content of major constituents (khusimol, β-vetivenene and β-vetispirene).ISSN : 1041-2905 En ligne : http://www.tandfonline.com/doi/abs/10.1080/10412905.2006.9699129#.UaNvkdgYrOk

For example, epi-13-manool (47.6 %) was the major component of the fresh flower oil, but was not detected in the dried fower oil, whereas isolongifolol (15.5%), 2-nonanol (11.1%) and 7-hydroxycoumarin (9.7%) were the principal components of the dried flower oil. In the oils of both the fresh and dried leaves the major constituent was (E,E)-farnesol, although the proportion of this compound in the fresh leaf oil was considerably higher (37.3%) than that of the dried leaf oil (3.2%). (E,E)-farnesol was also the major component of the fresh twig oil (16.6%), but was absent from the dried twig oil, the major constituent of which was (E,E)-2,4-decadienal (2.4%); however, this was not detected in the fresh twig oil.

As the mass of the needles increased from 0–100% with respect to twig contents, the % oil yield decreased and the composition changed. Pure needle oil was found to be much richer in oxygenated compounds than that of pure twig oil with a corresponding reduction in amounts of monoterpene hydrocarbons. Marker compounds were chosen in order to show the chemical variation of the oils with respect to different ratio of needles to twigs distilled. By computing both physical and chemical variations, it is suggested that a fair compromise between the yield and the concentration of oxygenated compounds is the 75% needle 25% twig mixture, which appears to be the most suitable proportion of plant material for pine oil production from P. brutia.

Braga, Auteur Année de publication : 2006 Article en page(s) : pp. 455-461 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Thymol Bacterial adhesiveness Escherichia coli Staphylococcus aureus Human vaginal cells Résumé : Adhesion is an important starting event in the pathogenesis of bacterial infection because the microorganisms must first adhere to host tissue in order to multiply and create a colony or colonies before specific symptoms allow the disease process to be detected. This is particularly true in the case of female urogenital infections, including urinary tract infections, bacterial vaginosis and vaginitis. Thymol is a component of thyme essential oil, which has been reported to possess interesting antimicrobial effects on various microorganisms; however, its ability to interact with the adhesion of bacteria (an important determinant of bacterial virulence) has not been investigated.
The aim of this study was to assess whether thymol interferes with the adhesion of Escherichia coli and Staphylococcus aureus to human vaginal epithelial cells. The adhesiveness of three strains of E. coli to vaginal cells was significantly reduced at thymol concentrations ranging from 1/2 MIC to 1/32 MIC, and in three strains of S. aureus at concentrations ranging from 1/2 MIC to 1/16 MIC.
Sub-MICs down to 1/8 MIC also significantly reduced the hemagglutination of E. coli, which is correlated with fimbriation and thus provides a clue relating to the interference of thymol, a phenolic structure with an hydroxyl group, on the physicochemical characteristics of the outer surface of bacteria. This is of interest for the strategy of protecting against vaginitis or vaginosis using drugs other than antibiotics.ISSN : 1041-2905 En ligne : http://www.tandfonline.com/doi/abs/10.1080/10412905.2006.9699140#.UaSMONgYrOk [article] Thymol : Inhibitory activity on escherichia coli and staphylococcus aureus adhesion to human vaginal cells [texte imprimé] / Monica Dal Sasso, Auteur ; Maria Culici, Auteur ; Pier C.
