Titre : Leaf secretory structure and volatile compounds of eugenia copacabanensis kiaersk. (Myrtaceae) Type de document : texte imprimé Auteurs : Rosani do Carmo de O. Arruda, Auteur ; Cristiane P. Victório, Auteur Année de publication : 2012 Article en page(s) : pp. 1-6 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Eugenia copacabanensis Kiaersk Myrtaceae Atlantic rainforest α-pinene β-pinene Caryophyllene Restinga Secretory activity Simultaneous-distillation extraction Volatile composition Index. décimale : 646 Résumé : Eugenia copacabanensis Kiaersk. (Myrtaceae) is restricted to salt marshes or restinga areas along the southeastern coast of Brazil. This work analyzes the leaf secretory structures and volatile compounds produced in E. copacabanensis plants collected in the Marambaia Restinga of Rio de Janeiro City. Simultaneous-distillation extraction (SDE), when combined with GC-FID and GC/MS analyses, revealed α-pinene (20.2%) and β-pinene (50.4%) as the major volatiles of this plant, proving that it is rich in monoterpenes. trans-Caryophyllene (10.3%) was the only sesquiterpene identified. Using light microscopy, E. copacabanensis leaves presented numerous randomly distributed oil secretory cavities in the mesophyll, while histochemical tests showed the presence of terpenoids and lipophilic substances accumulated in secretory cavities and parenchyma cells.

(Myrtaceae) was analyzed by GC and CG/MS. Forty-four components were identified, representing around 83% of total oil. The major components were α-bisabolol (23.6%) and α-bisabolol oxide B (11.5%). The cytotoxicity of the oil and of a fraction rich in α-bisabolol was tested in vitro against U251 (glioma), UACC-62 (melanoma), MCF-7 (breast), NC1-ADR/RES (ovarian-resistant), 786.0 (kidney), NCI-H460 (lung), PC-3 (prostate), OVCAR-3 (ovarian), HT-29 (colon) and K562 (leukemia) human cancer cells and against VERO (no cancer cell). The oil exhibited antiproliferative activity against all cell lines (TGI < 100 μg/mL), with exception of NCI-H460 cell line (TGI > 125 μg/mL). The highest activity of the oil was observed against U251 (TGI 20.46 μg/mL), 786.0 (TGI 20.74 μg/mL), UACC-62 (TGI 26.98 μg/mL) and PC-3 (TGI 27.63 μg/mL) cell lines. The fraction rich in α-bisabol showed a similar activity profile. It was most active against OVCAR-3 (TGI 8.58 μg/mL) and 786.0 (TGI 8.74 μg/mL).

They were investigated for the presence of four drimane-type sesquiterpenes: polygodial (1), isopolygodial (2), drimenol (3) and confertifolin (4), previously isolated from P. acuminatum; and the presence of three flavonoids: pinostrobin (5), flavokawin B (6) and cardamonin (7), previously isolated from P. persicaria. Results showed that among the five species of Persicaria section studied, two species contained sesquiterpenes 1–4 but not flavonoids 5–7, other two species contained flavonoids 5–7 but not sesquiterpenes 1–4, and only one species contained compounds 1–7. These results add evidences to a previous proposal to sub-classify the Persicaria section of Polygonum genus from a chemotaxonomic point of view.

Titre : Seasonal evaluation and chemical composition of volatile fractions from piper claussenianum by hydrodistillation and SPME Type de document : texte imprimé Auteurs : André Mesquita Marques, Auteur ; Maria Auxiliadora Coelho Kaplan, Auteur Année de publication : 2012 Article en page(s) : pp. 15-19 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Piper claussenianum Nerolidol Essential oil SPME Hydrodistillation Index. décimale : 646 Résumé : The essential oils from Piper species are chemically diverse, with several biological activities as well as commercial and pharmacological values reported. This work aims to compare the volatile constituents from leaves and inflorescences obtained by two different extraction techniques and show the seasonal variation of nerolidol in the essential oil from leaves of Piper claussenianum. The P. claussenianum volatile components were obtained by headspace solid-phase microextraction (HS-SPME) and hydrodistillation, coupled to gas chromatography/mass spectrometry (GC/MS) analysis. Leaf and inflorescence volatile fractions were analyzed in fresh and dried conditions. In total, 40 compounds were identified, accounting for 88.8–97.7% of the constituents. The high percentage of nerolidol in the leaves and linalool in the inflorescences were remarkable in this species, accounting for up to 77.0% and up to 50.0%, respectively, collected monthly. Results of (E)-nerolidol seasonal variation study carried out in the growth period of January/December 2009, suggest the plant leaves which provide an essential oil with high content of (E)-nerolidol over 88.0% are primarily observed in the September/December collection period.

Garcia, Auteur Année de publication : 2012 Article en page(s) : pp. 38-44 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Anti-inflammatory activity Essential oils Inflammatory diseases Review Index. décimale : 646 Résumé : There are many diseases that are associated with inflammation, such as infections by bacteria, virus and protozoa, autoimmune diseases such as arthritis and diabetes, Alzheimer's disease, and cancer. There are many medications available to prevent or minimize the progression of the inflammation; they include non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids, but they have some secondary effects. Traditional medicine has been used to address the health demands of the population and nowadays it presents many opportunities in health care. Essential oils are use in this medicine to treat many diseases.
In a review of the last five years it was found that several essential oils with anti-inflammatory activity were isolated from 43 plants. In some cases, oils of the same genus but different species have this activity, such as the essential oils obtained from three species of genus Origanum, as well as three oils from three species of the Citrus genus, and three from the Pimpinella genus. In many cases the essential oil composition obtained has been determined, and in some cases the anti-inflammatory activity of the main compounds of these essential oils has been evaluated, such as carvacrol and isoeugenol, which showed an important anti-inflammatory activity. On the basis of this review, we can say that some essential oils could be an important source for the treatment of inflammatory diseases.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.tandfonline.com/doi/abs/10.1080/10412905.2011.9700480 [article] Anti-inflammatory activity of some essential oils [texte imprimé] / Salud G.

Lamiaceae Essential oil composition Antibacterial activity Cis-sabinene hydrate Terpinen-4-ol Index. décimale : 646 Résumé : Origanum majorana L. (Lamiaceae) is a plant that is used in gastronomy and natural medicine. The plant material used in this study was collected at San Isidro de Apartaderos, Mérida State. A yield of 0.6% of essential oil was obtained by hydro-distillation using a Clevenger trap. The main constituents found were: cis-sabinene hydrate (30.2%), terpinen-4-ol (28.8%), γ-terpinene (7.2%), α-terpineol (6.9%), trans-sabinene hydrate (4.4%), linalyl acetate (3.8%), and α-terpinene (3.6%). The essential oil was also fractionated over a silica gel dry column. Two main fractions were isolated, the first containing 67.6% of cis-sabinene hydrate and the second 72.8% of terpinen-4-ol. The antibacterial activity of the oil was determined using the agar diffusion method and it was found that it was active against Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, and Klebsiella pneumoniae. Antibacterial activity of the fractions obtained by dry column chromatography was also tested. It was found that the fraction rich in cis-sabinene hydrate was more active than the one rich in terpinen-4-ol. It was concluded that in the essential oil of Origanum majorana, cis-sabinene hydrate is the more important compound responsible for inhibition of bacterial growth.

This extract exerted in vivo a significant anti-inflammatory activity. Subsequent fractionation and analysis of the extract has led to the isolation and characterization as major constituents of apigenin (1), rutin (quercetin 3-O—L-rhamnopyranosyl-(1->6)—D-glucopyranoside) (2) and quercetin (3) and of rutin decaacetate (4) and quercetin pentaacetate (5) from acetylated methanolic extract. Their structures were elucidated by spectral methods. The bioassay-directed analysis of flavonols 1–3 indicated that rutin (2) and quercetin (3) were the most active compounds, whereas apigenin showed no significant activity. The acetylation process increased the anti-inflammatory activity but decreased the antioxidant activity. The MeOH extract and all of flavonoids tested did not show in vitro significant cytotoxic effect in J774.A1 macrophage cell line.

The volatile fraction of cold-pressed Persian lime oil is characterized by a higher content of limonene, γ-terpinene and esters and a lower content of β-pinene, sesquiterpene hydrocarbons, alcohols and aldehydes than cold-pressed Key lime oils. In petitgrain oils the oxygenated compounds are present at levels higher than the peel oils. Oxypeucedanin, probably due to the extraction technology, was almost absent in cold-pressed Key lime type A, while it is present in cold-pressed Key lime type B and in Persian lime oil. The en-separation was performed by direct enantioselective GC (esGC) and by multidimensional GC (MDGC) to obtain the most appropriate antiomeric separation of all the components analyzed. The enantiomeric excess of S-(-)-α-pinene, 1S,4R-(-)-camphene, S-(-)-β-pinene, S-(-)-sabinene, and R-(-)-β-phellandrene are lower in cold-pressed Persian lime oil than in Key lime oils.
