Abstract

Glaucosciadium cordifolium (Boiss.) Burtt. & Davis, which is a monotypic species naturally grown in Turkey belonging to the Apiaceae (Umbelliferae) family. In this study, the essential oil obtained from G. cordifolium was analyzed and evaluated for its antimicrobial effects. In chemical studies, the analyzes of essential oil compounds obtained from the aerial parts of plants by hydrodistillation were carried out with GC-FID and GC-MS. In total, 23 compounds were identified making up 98.7% of the total volatile constituents. Sabinene (42.1%), α-pinene (17.1%), and α-phellandrene (10.1%) were found as the main constituents in the oil. In antimicrobial studies, the anticandidal and antibacterial effects of essential oils were tested against 14 pathogenic microorganisms according to the standard protocols of the Clinical Laboratory Standards Institute (CLSI). It has been determined that essential oils have a very weak inhibitory effect when compared with standard antibacterial agents. MIC values of 1800, 3600 µg/Ml, and higher were determined. In addition, it was determined that it showed inhibitory effects, especially against C. krusei at a concentration of 250 µg/mL, with MIC values ranging from 250 to 2000 µg/mL.
