Abstract: The aim of this study is to evaluate the chemical composition and the antioxidant and antimicrobial activities of EOs of C. nepeta collected in two different seasons, spring (leaves) and autumn (leaves and flowers) and to understand the relationship between seasonality composition and these biological activities. EOs were extracted by hydrodistillation of aerial parts of the plants wild grown in Évora (Alentejo) and their chemical composition was evaluated by GC-FID and GC-MS. Antioxidant activity was determined by β -carotene/linoleic acid system, total reducing power assay and DPPH radical methods [1]. Antimicrobial activity was assessed against Gram-negative and Gram-positive clinical isolates and food spoilage fungi [2,3].
