“…The diameters of the inhibition halos formed were measured, and the minimum inhibitory concentration (MIC), the lowest concentration that inhibited the growth of the microorganism, was calculated. Chloramphenicol (standard antibiotic) was used as a positive control, and DMSO as the negative control [8]. The micro-organisms S. choleraesuis, P. aeruginosa, E. coli and S. aureus were transferred to plates containing…”

Essential oils from Mentha piperita, Cymbopogon citratus, Rosmarinus officinalis, Peumus boldus and Foeniculum vulgare were extracted by hydrodistillation, chemically characterized and quantified by GC/MS and GC/FID. The principal componentes in the essential oil of M. piperita (carvone and limonene), C. citratus (geranial, neral and myrcene), R. officinalis (1,8-cineole, camphor and α-pinene), P. boldus (α-terpinyl formate, p-cymene and 1,8-cineole) and F. vulgare (methyl chavicol, limonene and fenchone) were identified. The oils were tested for antioxidant activity employing the DPPH (2,2-diphenyl-1-picryl-hydrazyl) radical-capture method, the oxidation of the β-carotene/linoleic acid system, and the ABTS radical-capture method. The essential oils were not effective. The antioxidant activities of the oils were determined by the hydroxyl method, and the highest activity (62.80%) was observed with the essential oil from M. piperita. Activities of 1.54 and 1.82 μg μg −1 , respectively, were observed for the essential oils from C. citratus and P. Boldus using the phosphomolybdenum method. No activity was observed with respect to reducing power. The essential oil from C. citratus was effective in inhibiting the growth of L. monocytogenes ( How to cite this paper: Rezende,

“…For the negative control, 10 μL of DMSO was applied. For the positive standard, a solution of 1000 mg·L −1 of chloramphenicol (CL) was used [12]. The sensitivity of the bacteria to different concentrations of essential oils was determined from the diameters of the inhibition zones.…”

The essential oils from Mentha viridis L. and Mentha pulegium L. were characterized by gas chromatography coupled to mass spectrometry (GC-MS). These oils were obtained by hydrodistillation and presented linalool (40.70%), carvone (13.52%) and α-terpinene (8.56%) as the principal constituents in the essential oil from Mentha viridis L. Pulegone (50.01%), menthol (31.90%) and menthone (16.56%) were the principal constituents in the essential oil from Mentha pulegium L. These essential oils (in concentrations ranging from 3.91 to 500 μL·mL −1 ) showed satisfactory activities against Escherichia coli, Listeria monocytogenes, Salmonella choleraesuis and Staphylococcus aureus. The antioxidant activities with 2-deoxyribose and phosphomolybdenum and the reducing power (in concentrations ranging from 0.78 to 1000 μL·mL −1 ) were determined. The antioxidant activity was observed for the two oils evaluated by the phosphomolybdenum and 2-deoxyribose methods, whereas the essential oil from M. viridis presented low antioxidant activity in the reducing power assay.

Abstract:The essential oil obtained from the leaves of Eugenia uniflora L., Myrtaceae, which grows in the Brazilian savannah, was studied by gas chromatography mass spectrometry (GC-MS). Furanodiene (1.2%) was thermally rearranged to curzerene (85.1%) to produce a combined content of 86.3%. GC analysis carried out under mild conditions (with a constant temperature of 100 o C) showed that the furanodiene concentration was threefold greater than the curzerene concentration, i.e., the essential oil contained 64.7% furanodiene and 21.6% curzerene. Germacrene B also rearranged to γ-elemene and the concentration of both was 2.3%. Special care should be taken when conventional gas chromatography analysis is used for quantifying compounds that can rearrange at high temperatures.
