“…LO is composed by linalool and linalyl acetate, and by more than hundred other compounds. 31 It has been demonstrated that its main components (linalool and linalyl acetate) are responsible for the anti-inflammatory activity. 32,33 Moreover, LO possesses antibacterial and antifungal properties, 28,34,35 pointing out its efficacy against Staphylococcus aureus that is the bacterium mostly responsible for burn wound infections.…”

One of the current challenges in wound care is the development of multifunctional dressings that can both protect the wound from external agents and promote the regeneration of the new tissue. Here, we show the combined use of two naturally derived compounds, sodium alginate and lavender essential oil, for the production of bioactive nanofibrous dressings by electrospinning, and their efficacy for the treatment of skin burns induced by midrange ultraviolet radiation (UVB). We demonstrate that the engineered dressings reduce the risk of microbial infection of the burn, since they stop the growth of Staphylococcus aureus. Furthermore, they are able to control and reduce the inflammatory response that is induced in human foreskin fibroblasts by lipopolysaccharides, and in rodents by UVB exposure. In particular, we report a remarkable reduction of pro-inflammatory cytokines when fibroblasts or animals are treated with the alginate-based nanofibers. The down-regulation of cytokines production and the absence of erythema on the skin of the treated animals confirm that the here described dressings are promising as advanced biomedical devices for burn management.

“…The lavender essential oil is very important economically and there is a huge world demand for it (Hughes, 1998). The lavender essential oil is used for the production of high price perfumes, fragrances and essences, in pharmaceutical products, and also in the cosmetic and food industries due to its phenolic metabolites (Singh et al, 1997;Al-Amier et al, 1999;Shellie et al, 2002;Moss et al, 2003;Chemat et al, 2006;Dob et al, 2006). Nevertheless, commercial oil composition presents great content variation, in part due to genetic differences among plant populations since lavender crops have been mostly propagated by seeds and problems such as low secondary metabolites synthesis and great variability among species are ruling (Nogueira & Romano, 2002).…”

ABSTRACT:Even though the Lavandula species may be propagated by seeds, it should not be the preferred propagation method because it causes a great lack of uniformity. On the other hand, asexually propagated lavender crops would provide more homogeneous crops, and clones from high quality plant material would increase the odds for obtaining a higher quality essential oil. However, problems such as poor rooting and restrict market availability for superior clones have been a problem in vegetative propagation of the Lavandula species. The objective of this work was to define which type and size of cutting is more adequate for cutting propagation of L. dentata, a very productive Lavandula species. Cuttings with 5, 8, 10 or 13 cm and from the apical or basal parts of stems cut from L. dentata stock plants were placed in Plantmax HT ® filled polystyrene foam trays and kept under intermittent mist system for two months. Averages of root number, length of the longest root, fresh and dry root weight, and percentage of rooting were evaluated. Apical cuttings combined 97.9% rooting with an average of 13.2 roots per cutting and basal cuttings 93.7% rooting with 2.98 roots per cutting. Apical cuttings with at least 10 cm in length were considered the most adequate for cutting propagation of L. dentata.Key words: vegetative propagation, lavender, medicinal plant RESUMO: Influência do tipo e tamanho de estaca no enraizamento de Lavandula dentata L. Apesar de serem propagadas por sementes, as espécies de Lavandula deveriam ser preferencialmente propagadas por estaquia devido a grande falta de uniformidade causada pela primeira, enquanto que a propagação assexual da alfazema permite maior homogeneidade da lavoura e o uso de clones de alta qualidade aumentaria as chances de se obter óleo essencial de alta qualidade. No entanto, o baixo poder de enraizamento e o mercado restrito de clones superiores têm sido problemas para a propagação vegetativa de espécies de alfazema. O objetivo deste trabalho foi definir qual tipo e tamanho de estaca seriam mais adequados para a propagação de L. dentata, espécie muito produtiva de Lavandula, por estaquia. Estacas com 5, 8, 10 ou 13 cm das partes apical e basal de ramos de plantas matrizes de L. dentata foram colocados em bandejas de isopor com o substrato Plantmax HT ® e mantidas em casa de vegetação sob nebulização por dois meses. As médias de número de raízes, comprimento da raiz mais longa, massa fresca e seca de raízes e porcentagem de enraizamento foram avaliadas. Estacas apicais apresentaram enraizamento de 97,9% e 13,2 raízes por estaca em média e as estacas basais 93,7% de enraizamento e 2,98 raízes por estaca. Estacas apicais com pelo menos 10 cm de comprimento foram consideradas as mais adequadas para a propagação da L. dentata por estaquia.

“…It is generally recognized that every 1-D peak must be sampled three or four times in order to obtain satisfactory 2-D information. This means that a 1-D peak with a 20 s base width requires a modulation period of no more than 6 s. [11][12][13][14] There have been various approaches regarding the type of modulator employed. The first commercial instrument employed, the thermal sweeper type modulator, was based on a thick stationary phase trap and the subsequential pulsed reinjection of the retained solutes by a rotating heater.…”

Comprehensive two-dimensional GC for the analysis of citrus essential oils

et al. 2005

View full text Add to dashboard Cite

The lemon essential oil volatile fraction is considered one of the most complex amongst all citrus oils being traditionally determined by monodimensional GC. This conventional method, although providing important qualitative/ quantitative information, lacks the necessary resolving power for the separation of several critical compounds. In the past, this has been often accomplished through the employment of conventional multidimensional chromatographic methods, which can only achieve the characterization of single parts of a sample and whose analysis times are generally high. Comprehensive bidimensional gas chromatography (GC × × × × × GC) is gaining an excellent reputation for the separation of complex samples. This powerful analytical technique is characterized by both an enhanced resolving power and a great potential for the classification of unknowns through chromatographic retention patterns. In this research, these features are exploited in the analysis of a lemon essential oil.
