In this study, the composition of the volatile oils obtained from the fruits of 8 Ferulago species (Ferulago cassia Boiss., F. isaurica Peşmen, F. humilis Boiss., F. macrosciadia Boiss. & Balansa, F. setifolia K.Koch, F. silaifolia (Boiss.) Boiss., F. syriaca Boiss., F. trojana Akalın & Pimenov) growing naturally in Türkiye were examined by means of GC/MS and GC-FID and α-pinene was determined to be present in the fruits of four species along with other monoterpenes as major components. Principal Component Analyses (PCA) and Hierarchical Cluster Analysis (HCA) was performed, utilizing ten major components in the eight essential oils. Also, a Venn diagram was used to demonstrate chemotaxonomical variations in the composition of the essential oils of eight Ferulago species.
