“…They are extremely important for disease prevention, since they inhibit and delay the oxidation of biomolecules by preventing the initiation or propagation of chain oxidation reactions (Kaur and Kapoor, 2001;Bamoniri et al, 2010;Quariachi et al, 2011). Due to the harmful effects that synthetic antioxidants may cause, such as toxicity and carcinogenicity, the interest in the discovery of natural antioxidants has increased considerably (Losso et al, 2007).…”

The essential oils are extracted from plant compounds and can present activities antimicrobial and antioxidant properties. The goals of the present study were: (a) to determine the chemical composition of the essential oil of Guarea kunthiana A. Juss using the method of gas chromatography coupled to mass spectrometry (GC-MS); (b) to evaluate the antimicrobial potential of this oil using the broth microdilution method against different microorganisms: five Gram-negative bacteria, four Gram-positive bacteria and a yeast and (c) to determine the antioxidant activity of the oil using the DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical assay. The GC-MS analyses allowed identifying 13 constituents, representing 96.52% of the essencial oil composition. The main compounds identified were α-zingiberene (34.48%), β-sesquiphellandrene (22.90%), and α-curcumene (16.17%). With respect to the antimicrobial activity, the essential oil was effective against all the microorganisms tested, except for the bacteria E. coli and K. pneumoniae, which were resistant to the action of the oil. From a general point of view, Gram-positive bacteria were more susceptible to the action of the essential oil than Gram-negative bacteria. The essential oil exhibited antioxidant potential.Keywords: Guarea kunthiana, essential oil, chemical composition, antimicrobial activity, antioxidant. Composição química, potencial antimicrobiano e antioxidante do óleo essencial de Guarea kunthiana A. Juss ResumoOs óleos essenciais são compostos extraídos de plantas e podem apresentar propriedades antimicrobianas e antioxidantes. O objetivo deste trabalho foi (a) determinar a composição química do óleo essencial de Guarea kunthiana A. Juss pelo método de cromatografia gasosa acoplada à espectrometria de massas (CG-EM); (b) avaliar o potencial antimicrobiano deste óleo pelo método de microdiluição em caldo frente a diferentes micro-organismos, sendo cinco bactérias Gram-negativas, quatro Gram-positivas uma levedura e (c) por fim, determinar a atividade antioxidante do óleo pelo método de captura do radical livre 2,2-difenil-1-picril hidrazil (DPPH). As análises de CG-EM resultaram na identificação de 13 constituintes, representando 96,52% da composição do óleo essencial. Os principais compostos identificados foram α-Zingibereno (34,48%), β-Sesquifelandreno (22,90%) e α-Curcumeno (16,17%). Em relação à atividade antimicrobiana, o óleo essencial foi efetivo frente a todos os micro-organismos testados exceto para as bactérias E. coli e K. pneumoniae, as quais se apresentaram resistentes à ação do óleo. Em geral, as bactérias Gram-positivas foram mais suscetíveis à ação do óleo essencial em relação às Gram-negativas. O óleo essencial apresentou potencial.Palavras-chave: Guarea kunthiana, óleo essencial, composição química, atividade antimicrobiana, antioxidante.

ABSTRACT. The essential oil composition of flowering aerial parts of Haplophyllum buhsei Boiss. (Rutaceae) from Iran was analyzed for the first time using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Thirty six compounds comprising 92.2% of the total oil were characterized. The main components were -caryophyllene (12.9%), limonene (9.7%), -pinene (7.9%), linalool (7.4%), α-pinene (6.4%) and 1,8-cineole (5.5%). Volatile oil of Haplophyllum buhsei Boiss. flowering aerial parts was dominated by the high content of monoterpene hydrocarbons (39.2%) and oxygenated monoterpenes (23.2%).

“…The antibacterial effects of essential oils (EOs) and their components have been examined recently and their antimicrobial properties have been mostly studied in vitro (Kim et al 1995;Ozcan et al 2003;Bamoniri et al 2010). The mechanism of action of EOs and their selectivity against bacteria remain poorly understood (Helander et al 1998;Runyoro et al 2010).…”

The combined effects of enterocin A with Thymus vulgaris essential oils (EOs) against Listeria monocytogenes and Escherichia coli O157:H7 were investigated in vitro by enumeration of surviving populations of testing pathogens and minimal inhibitory concentration (MIC) determination. Enterocin A was purified to homogeneity by RP-HPLC from the culture fluid of Enterococcus strain and thyme EOs were extracted from local Thymus vulgaris plants. The major constituent of thyme EOs oils determined by GC-MS was thymol (78.4 %). Combination of enterocin A with thyme EOs showed an enhanced bactericidal effect against Listeria monocytogenes. Checkerboard assay and isobologram construction displayed a synergistic interaction between these compounds against Listeria (FIC index <0.5). Moreover, the MIC value of enterocin A has fallen fivefold (from 4.57 to 0.9 μg/ml), while the MIC of thyme EOs decreased threefold (from 3.6 to 1.2 μg/ml). Treatments with enterocin A alone did not affect the growth of the enteric pathogen E. coli O157:H7. However, the addition of thyme EOs and enterocin A yielded a synergistic antimicrobial effect against E. coli (MIC thyme EOs decrease from 2.2 to 0.71 μg/ml). This is the first report on the combined effect of enterocin A and thyme EOs against food pathogen bacteria. This combination could be useful in food bio-preservation.
