Accordingly, there was 61.40% carvacrol
and 0.28% thymol identified in the composition of M.
The percentages of the main compounds were: EOLA-C: 55.28% citral, EOLOCa: 47.20% carvacrol
(BECKER et al., 2018), and EOLA-L: 59.66% linalool (HELDWEIN et al., 2012).
The oregano 'orejon' (Plectranthus amboinicus), which belongs to the Coleus genus (Lamiacea family) and is also known as 'french' oregano in Cuba, has shown to possess antitussive, bacteriostatic (70% ethanol), antioxidant (30% ethanol) and phytobiotic activities due to its essential oils, rich in thymol and carvacrol
(Menendez and Pavon, 1999; Bakkali et al, 2008).
and tea polyphenols increase ROS in cancer cells with a dose-dependent manner which is a sign of their pro-oxidant activity (16,20).
The quantification of thymol and carvacrol
(Sigma Aldrich) was performed in a gas chromatograph coupled to a flame ionization detector (GC-FID), operated under the same GC-MS conditions, except for the chromatographic column, which was HP-5 (30 m x 0.25 mm x 0.25 [micro]m) with nitrogen gas entrainment (99.99 % of purity).
trachycarpa Boiss.) growing in Turkey and that study showed that the major components of essential oils were 2,3,6-trimethylbenzaldehyde (38.9%) and myrcene (18.2%), [alpha]-pinene (35.9%), 2,5-dimethoxy-p-cymene (63.4%), [alpha]-pinene (31.8%) and sabinene (15.8%), (Z)-[beta]-ocimene (32.4%), p-cymene (18.4%), carvacrol
methyl ether (78.1%), [alpha]-pinene (25.4%), [alpha]-pinene (40.8%), trans-chrysanthenyl acetate (83.5%), p-cymene (45.8%), and (Z)- [beta]-ocimene (30.7%).
The study carried out by Mariuti and Bragnagnolo  reported several phenolic compounds that were isolated from oregano, including carvacrol
, and demonstrated a great possibility of using spices as good antioxidants and possible substitutes for the synthetic antioxidants, especially in mixtures consisting of unsaturated carbon compounds as substrate.
Further evaluations of LE nootkatone in combination with carvacrol
were conducted when the presence of spider mite silk was shown to interfere with LE nootkatone efficacy.
Based on table 5, the major components of Marze essential oil were carvacrol
(63.34%), 2-cyclohexen-1-one (10.2%) and caryophyllene (4.1%).
(2004) when evaluating the susceptibility of methicillin-susceptible and methicillin-resistant Staphylococci to oregano oil observed inhibition of both types of pathogens to the same extent with MIC values for carvacrol
of 0,015-0,03 %, v/v.
monocytogenes heat shocked at 45[degrees]C for 1 h showed increased resistance to 200 ppm carvacrol
(Ait-Ouazzou et al.
Previous studies done in different laboratories have reported that adding carvacrol
, cinnamic aldehyde, thyme oil or thymol to lamb rations increased the body weight gain, albeit non significantly (Chavez et al., 2008; Simitzis et al., 2008; Unal, 2011).
