RESUMO
Thymus linearis and its essential oil (EO) are used to cure a range of diseases in traditional medicine. GC-MS analysis of Thymus linearis EO revealed the presence of sixty-four components. Thymol (50.62%), carvacrol (13.23 %), carvacrol acetate (7.72%), ï¢-bisabolene (5.47%) and o-cymene (5.47%) are the only five basic constituents in the oil which accounts for 82.07% of oil. When compared to other compounds, the EO and its primary components thymol and carvacrol had the largest proportion of mortality in Meloidogyne javanica. Carvacrol has also been proven to be helpful in suppressing the hatching of M. javanica eggs. This is the first time T. linearis EO and its constituents, such as borneol and caryophyllene, have been studied for nematicidal action. The antioxidant activity of EO components and active compounds was assessed using the ABTS radical scavenging method. Thymol and carvacrol were found to exhibit high antioxidant activity. The IC50 of thymol and carvacrol are found to be 38.18 g/ml and 49.65 g/ml, respectively and are comparable to the positive control trolox (47.12 g/ml). Results clearly showed high potency for EO and its constituents, thymol and carvacrol as nematicidal and antioxidant agents.
