Abstract

This article focuses on the chemical composition and bioactive properties of six commercial essential oils (EOs) extracted from Foeniculum vulgare, Helichrysum stoechas, Mentha pulegium, Pinus pinaster, Ruta graveolens, and Thymus mastichina. Gas chromatography–mass spectrometry identified distinct major compounds in each EO, with H. stoechas and M. pulegium exhibiting strong antioxidant activity through free radical scavenging and lipid peroxidation inhibition. M. pulegium and T. mastichina EOs demonstrated the most potent antimicrobial effects against various bacteria and Candida species, while cytotoxicity assays on human dermal fibroblasts revealed dose-dependent toxicity, particularly notable for R. graveolens EO. The study suggests that M. pulegium and T. mastichina EOs hold potential for applications in food preservation and pharmaceutical industries, emphasizing the need to consider cytotoxicity in their use.
