Chemical composition of endemic Prangos species essential oils from Türkiye and multivariate analyses

OpenAlex İngilizce

In the present study, the essential oils of the endemic Prangos meliocarpoides Boiss. var. meliocarpoides and Prangos uechtritzii Boiss & Hausskn aerial parts (Karaman and Kayseri) were analysed the chemical compositions by GC-FID and GC/MS, respectively. The main constituents of the P. meliocarpoides var. meliocarpoides oil were α-phellandrene (16.9%), sabinene (16.2%), and γ-terpinene (13.2%). P. uechtritzii oils (Karaman and Kayseri) were characterized with p-cymene (19.4 and 18.4%), 7-epi-1,2-dehydrosesquicineole (8.7 and 9.0%) and spathulenol (8.3 and 10.3%) as main compounds, respectively. The essential oil compositions of P. uechtritzii were compared to the essential oil components in the literature. Multivariate statistical techniques, including principal component analysis and hierarchical clustering, were utilized to investigate the chemotaxonomic variations in the composition of P. uechtritzii essential oils across diverse geographical locations.
