Evaluation of the Antioxidant Properties and GC-MSD Analysis of Commercial Essential Oils from Plants of the Lamiaceae Family

Plants of the Lamiaceae family have been used for thousands years in cooking, as well phyto- and aromatherapy. Their essential oils are characterized by high antioxidant other types biological activities. In our study, phytochemical profile quantification oil components thyme, marjoram, sage were analyzed gas chromatography with mass-spectrometric detection (GC-MSD). The properties samples evaluated using total parameters (total capacity (TAC), ferric reducing power (FRP), activity (AOA) towards 2,2-diphenyl-1-picrylhydrazyl (DPPH•), phenolics Folin–Ciocalteu method). obtained FRP was 46–321-fold lower than TAC, which is consistent contents identified samples. Terpenes, isopropylmethylphenols, eugenol turned out to be major all determined their TAC AOA. method applicable thyme only. Its FRP, based on reaction phenolic antioxidants electrogenerated ferricyanide ions, agreed (329 ± 17 334 15 mg carvacrol per mL, respectively). had highest parameters, while showed weakest properties. Positive correlations (r = 0.8846–0.9964) obtained.
