GRAPHICAL ABSTRACT
ABSTRACT
The genus Teucrium L., a member of the Lamiaceae family, is represented by approximately 36 species in Türkiye. In this study, the essential oil composition of the aerial parts of Teucrium kotschyanum Poech collected from ˙Izmir (Ödemi¸s) was investigated by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) for the first time. The major compounds were identified as germacrene D (20.0%), α-cadinol (6.9%), β-bourbonene (6.6%), hexadecanoic acid (6.6%), δ-cadinene (5.9%) and manool (4.1%). The antibacterial and antifungal activities of the essential oil were evaluated against six bacteria and six fungi using the microdilution broth method. The essential oil exhibited limited antimicrobial activity, with the highest efficacy observed against Candida utilis (MIC:125 μg/mL) and the lowest against Staphylococcus epidermidis and Salmonella typhimurium (MIC: 2000 μg/mL).
