Composition and antimicrobial activity of Prangos platychlaena and P-uechtritzii

The chemical compositions and antimicrobial activities of the essential oils from two Turkish endemic species, Prangos platychlaena and P. uechtritzii, were investigated. Hydrodistillation was used to isolate the essential oils, and the chemical analyses were performed by GC and GC-MS. The antimicrobial activity was tested by the microdilution technique against Staphylococcus aureus, Enterococcus faecalis, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhimurium, Candida albicans, C. krusei, and C. tropicalis. delta-3-Carene (3.39%) and p-cymene (3.38%) were identified as major components in P. platychlaena, and alpha-pinene (40.82%), nonene (17.03%), beta-phellandrene (11.14%), delta-3-carene (7.39%), and p-cymene (4.90%) in P. uechtritzii.
