Abstract In this study the volatile components of four Inula species (Inula germanica L., I. bifrons (L.) L., I. ensifolia L., and I. salicina L.) were analysed by GC-FID/MS. A total of 141 chemical compounds were identified. A distinct volatile chemical profiles with high variation in the type of compounds was observed. Inula germanica was rich in oxygenated monoterpenes (54.7%), with cis-carvyl acetate (20.7%) and 1,8-cineole (14.6%) as main components. Sesquiterpenoids dominated in I. bifrons (60.3%), while the relatively high percentage of fatty acids characterized the other two species I. ensifolia and I. salicina (44.1 and 39.8%, respectively). Principal component analysis (PCA) and cluster analysis (CA) were used to investigate the variations in the volatiles of different Inula species.
