Journal of Essential Oil Research. Published online Feb This may be related to the stronger resistance of E. In addition, other experiments may be conducted to test the effect of lower concentrations in longer contact with microbial cells. Natural products have been recently investigated more thoroughly as promising agents for the prevention of oral diseases, especially plaque-related diseases such as dental caries 10, The disks impregnated with crude oil formed inhibition halos of 23 mm and 26 mm for E.

Antimicrobial activity of Lippia sidoides essential oil LSEOthymol and carvacrol determined by the agar dish diffusion method Ref. Antimicrobial activity of Lippia eidoides Cham.

Lippia – Wikipedia

Recently, quinones from LSEO have been described to possess cytotoxic activity Alteration in the yield of the essential oils, as well as the quantity of chemical constituents can still be observed due to the different phases of the plant’s development [ 2618 ] and at different times of the year [ 423 ].


After the growth of microorganisms, inocula were prepared in 0. Several studies involving the family Verbenaceae, occurring in the Brazilian Cerrado, have emphasized the popular use of many aromatic species. J Ethnopharmacol ; Activity of thymol, carvacrol, cinnamaldehyde and eugenol on oral bacteria. Botanic material was identified by Dr.

This work aims to determine the chemical composition of llippia essential oil of L. Integrated Taxonomic Information System. Colonization of teeth by cariogenic bacteria is one of the most important risk factors in the development of dental diseases with Streptococcus mutans being the primary species associated with the early dental caries process 1.

Gram-negative bacteria have siroides less rigid and chemically less complex cell wall than gram-positive ones, besides presenting higher lipid content Vargas et al. Retrieved 21 January Nogueira 2G.

Inhibition of Salmonella enteritidis and Staphylococcus aureus in nutrient broth by mint essential oil.

It is interesting to report that the oil extracted was collected at noon and therefore its chemical composition showed an appreciable amount of monoterpenes, a therapeutical potential that should not be ignored.

This variation is associated with geographical variability, genotype, climate and laboratory methods utilized to extract the oil. Several plants have been evaluated and presented promising results as preservatives and preventers of pathogenic microorganism growth in food, including Salmonella llippia and Staphylococcus aureus Tassou et al. J Xidoides Prod ; A recent study has suggested an antagonism of the essential oils with high percentages of p -cymene and phenolic monoterpenes thymol and carvacrolreducing the antimicrobial activity of the essential oil The three tested compounds exhibited relatively strong antibacterial and antifungal activity.


Results and Discussion The yield of Lippia sidoides essential oil was 0. All the tests were performed in triplicate and the mean lippiaa were calculated. According to MIC determination in the disk, the size of inhibition halos differed between E.

First, our study sidoide on a comparative evaluation of the activity of separate and combined compounds against microorganisms related to caries and oral infection, whereas the previous studies focused on essential oil sidlides alone or against other microorganisms. Within the limitation of the present study, it was demonstrated that LSEO, thymol and carvacrol are effective in inhibiting the growth of oral pathogens, supporting the traditional use of this plant in the treatment of oral infections Chemical composition of the essential oil from Lippia sidoides.
