The antibacterial mechanism of carvacrol and thymol
against Escherichia coli.
In this study, newly developed EOM containing eugenol, thymol
, and cinnamaldehyde was evaluated for efficacy to improve rumen fermentation pattern by in vitro batch culture.
The results of this analysis revealed that thymol
was the most effective of the three phytochemicals used.
In addition to carvacrol and thymol
, there were other main compounds detected in the essential oil of L.
, 2-isopropyl-5-methylphenol, (purity >99%) was purchased from Sigma-AldrichChemie GmbH (Germany).
content is presented as a function of the drying temperatures (p<0.01) in figure 4.
A second group of emulsions was prepared with a same ratio of thymol
and conjugates, but the oil phase contained 20% to 50% thymol
Sterilized 6 millimeter (mm) diameter absorbent paper disks were drenched with 30 |L of thymol
at 10.000 [micro]g/ml, and citronellol and linalool solution in their "pure" form (at 850,000 [micro]g/mL).
Thirty-three phenolic compounds, predominantly phenol, alkyl phenol, thymol
, naphthol and alkyl naphthol, were identified in the final enriched product.
This study focuses on the effects of the natural phenols thymol
(2-Isopropyl-5-methylphenol) and isoeugenol (4-hydroxy-3-methoxy-1-propenylbenzeneclove) which are the main components of essential oils including oregano, thyme, and clove respectively.
 report on some aspects of the mechanism and kinetics of the oxidation of different lipid systems inhibited by the presence of thymol
, carvacrol, and eugenol, finding out the greater effectiveness of thymol
due to the greater stability of the thymol
radical; it is originated by the inductive effect of the isopropyl group located at the ortho position relative to the hydroxyl group.
MOEO chemical analysis showed that the two major compounds were thymol
(2.452 g/ml) and carvacrol (0.456 g/ml), whereas p-cymene, 1,8-cineole, and y-terpinen were in very low concentrations.
