905RESUMO.-Objetivou-se determinar atividade antisséptica do óleo essencial de Lippia origanoides na presença de leite bovino. A composição química do óleo essencial de alecrim pimenta foi determinada por cromatografia gasosa acoplada à espectrometria de massas (CG-EM), sendo detectados 53 compostos, dos quais 16 foram identificados (>0,1% área total). O carvacrol (32,7%), p-cimeno (23%), timilmetil éter, cariofileno (7,98%) e o γ-terpineno (5,40%) foram os componentes mais abundantes. A concentração inibitória mínima para Staphylococcus aureus ATCC 25923 e E. coli ATCC 8739 foi de 60µL/mL, enquanto para Salmonella Choleraesuis ATCC 35640 foi de 90µL/mL. A concentração bactericida mínima foi de 120µL/mL para as três bacté-rias. Avaliou-se a atividade antisséptica do óleo essencial na concentração de 120µL/mL na presença de leite bovino sobre as mesmas cepas bacterianas. O óleo em estudo apresentou efeito inibitório do crescimento das cepas em diferentes tempos de ação (p<0,05). S. aureus apresentou maiores índices de inibição após 5 min de contato e Escherichia coli e Salmonella Choleraesuis após 15 min. O óleo essencial de alecrim-pimenta revelou ser um potencial antimicrobiano natural, mesmo na presença de matéria orgâ-nica constituída de uma matriz nutricional complexa que é o leite bovino. This study aimed to determine the antiseptic activity of the essential oil of Lippia origanoides in the presence of bovine milk. The essential oil chemical composition was determined by gas chromatography-mass spectrometry (CG EM) 53 compounds were detected, of which 16 were identified (>0.1% total area). The carvacrol (32.7%), p-cymene (23%), thymil methyl ether (10.03%), caryophyllene (7.98 %) and γ-terpinene (5.40%) were the most abundant components. The minimum inhibitory concentration for Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 8739 was 60uL/mL, as for this Salmonella Choleraesuis ATCC 35640 was 90uL/mL. The minimum bactericidal concentration was 120μL/ mL for all three bacteria. We evaluated the antiseptic activity of the essential oil in the concentration of 120μL/mL in the presence of bovine milk for the same bacterial strains. The oil under study It showed an inhibitory effect of growth of the strains in different action times (p <0.05). S. aureus showed higher inhibition rates after 5 min of contact and E. coli and Salmonella Choleraesuis after 15 min. The essential oil Lippia origanoides proved to be a natural antimicrobial potential even in the presence of organic matter consists of a complex nutritional matrix is bovine milk.

“…Chemotype C has a similar aroma to the chemotype B of oregano, and therefore, in the cosmetics industry, as perfume, in addition to thymol, the oil under study has 18.87% of carvacrol and 18.03% of p-cimene, the latter being a precursor of thymol and carvacrol. According to Queiroz et al [9], these variations on the major compounds are due to genetic, environmental, climatic and age factors, leading to alterations in the production of secondary metabolites by the plant.…”

The Lippia oils are well known for the treatment of respiratory problems, as well as their oils have compounds that are possibly good antimicrobial agents. In order to confi rm the seasonal differences and also to observe the potential to infl uence the antimicrobial activity, it was evaluated antimicrobial activity of the essential oil of Lippia origanoides H K B against the strains of Staphylococcus aureus, Escherichia coli and Candida albicans. Methodology: leaves of Lippia origanoides H.B.K. were harvested in the municipality of José de Freitas-PI, followed by their plants by the hydrodistillation process. Afterwards the oil was subjected to the analysis of techniques by Gas Chromatography coupled to GC-MS Mass Spectrometry for the identifi cation of its most important components. The test for its activities was bactericidal and fungicidal at the concentrations of 100, 300, 600 and 900 μg / mL. According to the analysis of the oil in the study, the results are classifi ed as chemotactic C, since it presents 55.53% of thymbrite as the majority of the total area analyzed. In addition, it presents 18.87% of carvacrol and 18.03% of p-cimene, the latter being a precursor of thymol and carvacrol. Events reported to results are due to the major compounds present in the oil. After 24 hours of growth, inhibition can be detected in some of the tested, as well as, it was noticed that the diluted in saline did not present positive results as expected for control. However, the oil at concentrations of 100, 300, 600 and 900 μg / ml inhibited growth against E. coli. Inhibition of the Staphylococcus aureus strain was observed at concentrations of 300, 600 and 900 μg / mL and against candida albicans there was inhibition at the concentrations of 300, 600 and 900 μg / mL. At the concentration of 100 μg / mL against the last strains there was no inhibition. The antimicrobial action is derived from the essential oil itself and the main responsible for it are the main components present, thymol and carvacrol and or association thereof, as well as resulting from hydrophobicity, permeability of the membrane. Conclusion: It was perceived that the essential oil of Lippia origanoides H. B. K. presented antimicrobial action as strains of Staphylococcus aureus, Escherichia coli and Candida albicans. At the concentration of 600 μg / mL there was a greater action against bacterial strains and against the fungal strain, 900 μg / mL, with a higher inhibition index. Therefore, a L. origanoides presents itself as promising for the development of new phytotherapics, faster and at a lower cost.
