The essential oil, aroma, and fatty acid compositions of Salvia cerino-pruinosa var. cerino-pruinosa, S. cerino-pruinosa var. elazigensis, S. pseudeuphratica, S. rosifolia, and S. kurdica collected in 2015, 2016, and 2017 were analysed by GC-FID, GC/MS/Head Space and GC/MS. The results were evaluated chemometrically for principal component analyses and hierarchical clustering analyses using Minitab program. The main components of their essential oils have been determined as germacrene-D (41.79 % highest for these species), camphor (55.80 %), linalool (33.38 %), caryophyllene oxide (32.99 %), 1,8-cineole (26.30 %) and geraniol acetate (31.63 %), while for aroma 1,8-cineole (45.95 % highest for these species), camphor (58.54 %), D-limonene (40.83 %), linalool (27.67 %) and cis-linalool oxide (25.87 %). Oleic (72.65 % highest for these species), erucic (44.61 %), 2-palmitoleic (42.17 %) and nervonic (32.61 %) acids were determined as major components of their fatty acids. According to the PCA and HCA, the essential oil components of these Salvia taxa unaffected by the years, and accordingly, the Salvia taxa grouped among themselves.
