The genus Thymus includes several species that are used as avouring, food preservative as well as in cosmetics. Their secondary metabolites have been extensively studied for pharmacological e ects. Nonetheless, some species are neglected and deserve to be explored for chemical composition and biological activities. This is the case with Thymus alternans, a Carpathian bush used as a food additive and for the preparation of a traditional herbal medicine. In this work, we have analysed the chemical composition of T. alternans essential oil by GC and GC-MS and evaluated its antimicrobial and antioxidant activity by disc di usion, DPPH, ABTS and FRAP methods, respectively. Results showed that T. alternans belongs to the nerolidol chemotype, being rich of this sesquiterpene alcohol (15.8%) which might contribute to the antimicrobial (particularly e ective on C. albicans growth) and antioxidant (weak inhibition on ABTS radical and reducing power) activities observed.

Abstract
The genus Thymus includes several species that are used as avouring, food preservative as well as in cosmetics. Their secondary metabolites have been extensively studied for pharmacological e ects. Nonetheless, some species are neglected and deserve to be explored for chemical composition and biological activities. This is the case with Thymus alternans, a Carpathian bush used as a food additive and for the preparation of a traditional herbal medicine. In this work, we have analysed the chemical composition of T. alternans essential oil by GC and GC-MS and evaluated its antimicrobial and antioxidant activity by disc di usion, DPPH, ABTS and FRAP methods, respectively. Results showed that T. alternans belongs to the nerolidol chemotype, being rich of this sesquiterpene alcohol (15.8%) which might contribute to the antimicrobial (particularly e ective on C. albicans growth) and antioxidant (weak inhibition on ABTS radical and reducing power) activities observed.File | Dimensione | Formato | |
