The essential oils used in the present study were thyme oil (Thymus vulgaris L.)
P0123774 and summer savory oil (Satureja hortensis L.) P0118884, both purchased from
Frey + Lau GmbH, Henstedt-Ulzburg, Germany. Gas chromatography-flame ionization (GCFID)
and gas chromatography–mass spectrometry (GC-MS) analyses were used for
determining the qualitative and quantitative composition of oils, as described previously
(Stevic et al., 2014).
